How to create mobile apps that can recognize location/orientation of 2D imges from the CAM
I am interested in finding out how mobile applications can recognize the location and orientation of a pre-determined 2D image/logo/glyph via live video from the camera.
For iPhone or Android, what libraries are used, and more importantly, are there any examples out there that demonstrate this?
Thanks! | 11

I would be interested to know, where are the advantages and disadvantages of each vision-based mobile Augmented Reality Frameworks? For what should be decide in which case? Would you choose Vuforia in any case, because it is free and without branding? What are important features are missing in one of the frameworks? Are there limits on the free version of Metaio SDK (except branding and Metaio splash-screen)?
I think these are the most important Frameworks to support iOS and Android. I know that metaio support movie textures and MD2 (Animation) Export and Vuforia not (at least not in the basic state).
Edit:
Here is a 3 hour session reviewed the best Mobile AR SDKs in the market and how to get started with them: Tutorial: Top 10 Augmented Reality SDKs for Developers
You should also check out ARLab from Augmented Reality Lab S.L. This has different AR-SDKs for AR Browser, Image Matching, Image Tracking, 3D engine, Virtual buttons. But this is not free.
Wikitude's ARchitect SDK has an Vuforia-Extension and Blackberry 10 Support. This could also be very interesting.
The Layar SDK is now available for iOS and Android with 3D, animation, AR Video and QR-Code Scanner
DARAM also appears a good SDK for Android, iOS, Windows 8 and Mac.
ARPA has a Unity-Plugin and a Google Glass SDK.
Here is a good comparison chart for Augmented Reality SDKs and frameworks
Apple has acquired Metaio. Metaio's future uncertain. (May 28, 2015)
Magic Leap Announces Its Augmented Reality Developer SDK for Unreal and Unity
Vuforia now has paid licensing and ability to demo apps without a watermark on their no-cost Starter plan - it now appears only during the first app launch in a particular day. This is to support developers who want to do demos to clients without showing the watermark. (May 6, 2015), Qualcomm sell its Vuforia business to PTC (Oct 12, 2015)
ARKit iOS 11 introduces ARKit, a new framework that allows you to easily create unparalleled augmented reality experiences for iPhone and iPad. By blending digital objects and information with the environment around you, ARKit takes apps beyond the screen, freeing them to interact with the real world in entirely new ways. (Juni 2017)
8th Wall XR is the world's first AR platform that works on all commonly available iOS and Android phones and integrates seamlessly with ARKit and ARCore. (August 2017)
ARCore is Google’s answer to Apple’s ARKit. It is designed to bring augmented reality capabilities to all Android phones in a relatively simple way. It’s also replacing the Project Tango, which required specialized hardware to run. | 11

Android realtime location tracking for 3D model augmented reality
I'm trying to implement a location-based AR solution similar to the GPS/Location tracking feature of Metaio Unifeye SDK (they stop support ARMv6 devices since their 2.5 version, but I must target those devices)
I want my users to be able to view a 10-meter high humanoid monster 3D Model in a 0.5 km radius area.
It must be a non-optical solution in which:
- Location (from GPS or Network provider) and compass will be used as reference for camera manipulation.
- Sensors may help estimating.
Is there any existing implementation (library or tutorial) for realtime location tracking sufficient for my requirement? | 11

camera overlay change with bearing and elevation
Folks,
I am trying to get a utility as shown in the picture below. Basically the camera display window covers part of the device's screen and a list of points that are connected by a curve or straight line are presented over the camera view as an overlay. I understand this can be drawn using quartz but this is less than half of my problem.
The real issue is that the overlay should present different points as the bearing and elevation changes.
For example:
if the bearing has to change +5 degrees and elevation +2 degrees, then PT1 will be next to the right edge of the camera view, PT2 will also move to the right and PT3 will be visible.
Another movement that changes the bearing +10 degrees would make PT1 not visible, PT2 at the right, PT3 middle and PT4 on the left edge of the camera view.
My questions after the picture:
Is it possible to have a view that is substantially larger than the size of the camera view (as shown below) and use some methods (I need to research these) to move the view when bearing/elevation changes? Is it recommended performance wise?
Is quartz the way to go here? What else do I need (other then of course AVFoundation for the camera and corelocation/motion)? Since my application is only iOS 7 I can use any new methods/APIs exclusive to iOS 7.
Aside from raywendelrich's tutorial on the augmented reality game, are there any tutorials that you know of that could help me with this endeavor? | 11

Augmented reality: Rendering function
My question builds up on this thread: Computer Vision / Augmented Reality: how to overlay 3D objects over vision? and on its first answer. I want to build an application that projects on real time the position of a fictional 3D object into a video feed, but the first step I have to take is: How can I do this over a single image?
What I am going for at the moment is having some kind of function that given a picture, its 6D pose (position + orientation), a 3D object (on fbx, 3ds, or something easily convertable to or from others), and its own position and orientation, returns me the projection of the 3D object over the image. Once I have that, I should be able to apply it over every frame of the video feed (how will I get the 6D information of the camera is a problem I'll deal with later)
My problem is that I am unsure where to find such a function, if it even exists. It should be offered like some kind of script or API so an external program can make use of it. Where should I look? Unity? Some kind of OpenCL functionality? So far my reading has not given me any conclusive answers, and as I am a novice in the topic, I'm sure a steep learning curve is ahead and I'd rather put my efforts on the right direction. Thank you | 11

AR ODG application for conference calls
I'm researching AR frameworks in order to select the best option for developing conference call/ meeting application for ODG glasses.
I got only a few directions for selecting a framework:
Performance of video streaming (capturing and encoding) must be watched closely to avoid overheating and excessive power consumption,
Should support extended tracking and
Video capturing should not be frame by frame.
I have no experience with AR field in general, and I would really appreciate if you can let me know your opinion or to give me some guidance on how to choose the best-fitted framework. | 11

Can ARKit detect specific surfaces as planes?
Using iOS 11 and iOS 12 and ARKit, we are currently able to detect planes on horizontal surfaces, and we may also visualize that plane on the surface.
I am wondering if we can declare, through some sort of image file, specific surfaces in which we want to detect planes? (possibly ignoring all other planes that ARKit detects from other surfaces)
If that is not possible, could we then perhaps capture the plane detected (via an image), to which we could then process through a CoreML model which identifies that specific surface? | 11

Which format file for 3d model SceneKit/ARKit better to use
I read several tutorials how to place 3d objects in SceneKit/ARKit applications and all of them uses .scn format files for the objects.
But I found there is no any issues if I use original .dae format and do not convert it to .scn format.
I don't really see any difference between .dae and .scn formats.
Actually result seems to me the same but can you explain what the difference between them and what I should use in what cases?

DK2 Head tracking not working "HMD powered off, check HDMI connection" on Windows
Part 1 - Description of the problem
I have the DK2 and I am working on a VR project. This project uses FirefoxNightly. I've downloaded it and installed the WebVR Enabler Add-On
Got this from http://mozvr.com/downloads/
I have also downloaded and installed the latest SDK and Runtime for Windows from https://developer.oculus.com/downloads/
I am also getting this on the Oculus Configuration Utility (while the oculus is plugged in):
However, I have gone on another computer with windows.. installed everything just like on this windows computer and it clearly shows the Oculus Rift connected properly but the head tracking still not working.
EDIT: I just tried connecting the oculus rift to this "second" pc ( dell laptop ) and now it doesn't even recognize the oculus rift. Still no head tracking.
EDIT 2: I tried installing everything on a third PC without success. I'm getting "service unavailable" on the Oculus Configuration Utility
My display mode is set as shown in the image.
Part 2 - Questions
What am I doing wrong? Is there a step I forgot to do? The weird thing is, I have the same project running on Mac without having any problems. Yes, on windows I can see the screen through the oculus rift but head detection is just not present.
Part 3 - list of possible fixes that did not work
This reddit post talks about the firewall issue however I tried the oculus rift with the firewall disactivated without success.
This reddit post talks about a possible fix by reinstalling everything and updating certain drivers.. however I have followed this fix step by step without success.
This oculus forum post talks about the issue and one person proposes a fix that worked for him/her. I followed the fix without success.
Part 4 - System info
If you require specific translations let me know. It is in French.
Part 5 - List of things I have tried that have been thought of
I have reinstalled everything. SDK (is not even needed in fact), runtime, firefoxnightly, webvr add-on multiple times
I have rebooted my computer multiple times
I have tried the different Rift Display Mode
Basic demos from mozvr.com and other webvr based projects work fine but head tracking does not work.
My Oculus is not broken (maybe for windows), it works fine for the Mac.
I've tried using different HDMI cables and Different minUSB-USB cables without success.
Part 6 - Quotes from the forum
First post
This sounds like the same issue a lot of us are having with the 0.5
and 0.6 versions. It's not something wrong with the cables, but with
the Runtime itself. Direct-mode works flawlessly and in Extended mode
the rift still displays a picture, altho without any tracking etc from
the runtime. Hoping it'll be fixed in the next update. | 00

Unity hololens using holotoolkit FOV always 16.97196
I am using unity with holotoolkit for developing app for hololens. The issue is the Field of View (FOV) of the main camera is always 16.97196 no matter what values is input. I even added a script to deliberately set the FOV value to 60 but it resets to 16.97196. Can the FOV value be set the user requirements. | 00

Testing ARKit without iPhone6s or newer
I am before decision to download Xcode9. I want to play with new framework - ARKit. I know that to run app with ARKit I need a device with A9 chip or newer. Unfortunately I have an older one.

Facebook AR Studio - Importing Animations
I'm trying to import a 3d object in .fbx format into the Facebook AR Studio. The object was created and animated in Blender. The AR Studio does not support 'Baked' animations, but I'm wondering if it's possible to somehow import the animation into the studio, as opposed to scripting the entire animation, due to the complexity of the object (number of bones and motions).
I'm new to AR and 3d modeling so any input or direction is appreciated. | 00

How can I use my webcam inside an Azure windows server virtual machine?
I have a Windows server 2016 vm on Azure and I am trying to do some work in Augmented Reality using Vuforia and Unity. An essential part of this is being able to use my webcam but once I am inside the VM it doesnt recognise my integrated webcam. I tried to connect a webcam through USB as well but this doesn't work either. Is this an impossible task...getting a server instance to recognise webcams on my laptop or is it actually possible?

How to convert OBJ with MTL file to USDZ format
So I have an OBJ 3D model with its associated MTL file. The MTL file contains all the textures. However, when I convert the file to the USDZ format, the textures are not attributed to the file. This is the code I use.
xcrun usdz_converter /Users/SaiKambampati/Downloads/Models/object.obj /Users/SaiKambampati/Downloads/Models/object.usdz
The USDZ file is created but the attributes and textures are not applied. Is there any way to include the MTL file when converting the OBJ model to USDZ model? | 00

Location based AR with Three.js (+ React) - camera configuration?
I want to augment the image of a stationary webcam with location based markers. This is to be added to an existing React app that uses three.js (through react-three-fiber) in other parts already, so these technologies are to be reused.
While it is quite eays to calculate the position of the markers (locations known) relative to the camera (location known), I'm struggling with the configuration of the camera in order to get a good visual match between "real" object and AR marker.
I have created a codesandbox with an artificial example that illustrates the challenge.
Here's my attempt at configuring the camera:
const camera = {
position: [0, 1.5, 0],
fov: 85,
near: 0.005,
far: 1000
};
const bearing = 109; // degrees
<Canvas camera={camera}>
<Scene bearing={bearing}/>
</Canvas>
Further down in the scene component I’m rotating the camera according to the bearing of the webcam like so:
...
const rotation = { x: 0, y: bearing * -1, z: 0 };
camera.rotation.x = (rotation.x * Math.PI) / 180;
camera.rotation.y = (rotation.y * Math.PI) / 180;
camera.rotation.z = (rotation.z * Math.PI) / 180;
...
Any tips/thoughts on how to get that camera configured for a good match of three.js boxes and real life objects? | 00

How do I submit a Vuforia application for Facebook review as a simulator build?
I am creating an iOS app that uses Unity3D, the Vuforia AR SDK, and Prime31 Social Networking Plugins.
In order to publish a screenshot to a user's Facebook timeline, my app needs the "publish_actions" permission. To use this I need to submit the app for review by Facebook, in the form of an Xcode Simulator Build.
However, Vuforia does not support simulator builds:
https://developer.vuforia.com/resources/dev-guide/step-4-compiling-and-running-vuforia-sample-app
"Note: Vuforia applications do not build or work with the Simulator."

camera.rotation.z = (rotation.z * Math.PI) / 180;
...
Any tips/thoughts on how to get that camera configured for a good match of three.js boxes and real life objects? | 00

Unknown type name 'namespace' in Xcode 4.2
I am compiling QCAR SDK, but it prompts an error after I added more frameworks to the project.
// Matrices.h
//
#ifndef _QCAR_MATRIX_H_
#define _QCAR_MATRIX_H_
namespace QCAR
{
/// Matrix with 3 rows and 4 columns of float items
struct Matrix34F {
float data[3*4]; ///< Array of matrix items
};
/// Matrix with 4 rows and 4 columns of float items
struct Matrix44F {
float data[4*4]; ///< Array of matrix items
};
} // namespace QCAR
#endif //_QCAR_MATRIX_H_
In the line namespace QCAR, it said Unknown type name 'namespace'.
What should I do?

identifier float2 and float4 undefined (Oculus Rift)
For a school project we need to implement the oculus rift in a previously made DX9 engine. All is going well, but I am stuck at the distortion part of implementing the oculus.
I came to the part where I need to implement my shader for the barrel distortion and for that you use 'float2' and 'float4'. I can't seem to find these types in the OVR SDK or anywhere else. This results in 'undefined identifiers'.
Does anyone know where I can find these constant types?
Thanks! | 00

vuforia sample application code 100 error in airplane mode
I need to update an iOS app working with Vuforia.
The app compiles and runs normal, but I need to test airplane mode. In airplane mode, when trying to use the device's camera, I get this error:
Error initializing AR:Error Domain=vuforia_sample_application Code=100 "The operation couldn’t be completed."
I've been unable to find out what this error is.
What is error code 100? Also, does Vuforia need a web connection?
Thanks for your help. | 00

Getting "System": ambiguous symbol error using C++ CLI
I have a project (VS2012) that uses the 0.5.0.1 SDK. The SDK includes a System class under the OVR namespace (OVR::System). In a class that I wrote, I'm using ::System. This works and isn't what's giving me the problem. When I compile, I get error C2872: 'System': ambiguous symbol and the problematic files are typeinfo, xlocale, and xiosbase in C:....\Microsoft Visual Studio 12.0\VC\include. The error says that "System" could either be "System" or OVR::System. Is there a way around this? How can I get typeinfo, xlocale and xiosbase to use ::System and not OVR::System without changing the contents of the files (which I don't want to do)? | 00

intersection.object is a THREE.Mesh, so intersection.object.el is undefined! | 00

Oculus OVR_CAPI.cpp error
I'm currently working on a project where I need to read the Oculus Rift DK2 sensors. I have searched the web for usable samples, sadly the only samples I can find cause me a lot of trouble with SDK vesions and such. I found a tutorial on how to implement some basic C++ code to read the pitch, roll & yaw. I used the SDK for Windows V1.8.0.
#include "stdafx.h"
#include <iostream>
#include "../../OculusSDK/LibOVR/Include/OVR_CAPI.h"
#include <thread>
#include <iomanip>
#define COLW setw(15)
using namespace std;
int main()
{
// Initialize our session with the Oculus HMD.
if (ovr_Initialize(nullptr) == ovrSuccess)
{
ovrSession session = nullptr;
ovrGraphicsLuid luid;
ovrResult result = ovr_Create(&session, &luid);
if (result == ovrSuccess)
{ // Then we're connected to an HMD!
// Let's take a look at some orientation data.
ovrTrackingState ts;
while (true)
{
ts = ovr_GetTrackingState(session, 0, true);
ovrPoseStatef tempHeadPose = ts.HeadPose;
ovrPosef tempPose = tempHeadPose.ThePose;
ovrQuatf tempOrient = tempPose.Orientation;
cout << "Orientation (x,y,z): " << COLW << tempOrient.x << ","
<< COLW << tempOrient.y << "," << COLW << tempOrient.z
<< endl;
// Wait a bit to let us actually read stuff.
std::this_thread::sleep_for(std::chrono::milliseconds(100));
}
ovr_Destroy(session);
}
ovr_Shutdown();
// If we've fallen through to this point, the HMD is no longer
// connected.
}
return 0;
}
there are (as far as I know) no problems with this part.
when I included the OVR_CAPI.h the OVR_CAPI.cpp magically appears in the folder where OVR_CAPI.h is located. this cpp file contains the following:
#include "stdafx.h"
#include "OVR_CAPI.h"
OVR_PUBLIC_FUNCTION(ovrResult) ovr_Initialize(const ovrInitParams * params)
{
return OVR_PUBLIC_FUNCTION(ovrResult)();
}
when I try to build it errors:"expected an expression" and " C2062(type 'int' unexpected)" occur,both on Line 6.
is anyone familiar with this problem or can someone give me advice on how to get started with Oculus software? | 00

Argon.js: Error: A frame state has not yet been received
I am attempting to use argon.js server side so that I can convert lla coordinates to a predefined reference frame. I'm not rendering any graphics of course, I'm just using it to convert values. See SO question
Using Geo-coordintes Instead of Cartesian to Draw in Argon and A-Frame
for details.
Per that thread, I am trying to create a cesium entity for a fixed coordinate which I will later use to create other entities relative to it. When I do, everything runs until I get to the last line of the program var gtrefEntityPose = app.context.getEntityPose(gtrefEntity); where I receive Error: A frame state has not yet been received.
At first I thought this might be due to the setting the default reference entity to app.context.setDefaultReferenceFrame(app.context.localOriginEastUpSouth); since I did not have a local user yet due to it being server side. I looked up the documentation for setDefaultReferenceFrame as well as the possibility that I might need to use convertEntityReferenceFrame as well as the source code for each, but I am unable to make sense of it given my knowledge of the program.
I've put the error as well as my application code below.
Thanks for your help!

Aframe remove component inside for loop
I have a html template similar to the below code
<a-entity id="id1">
<a-entity template="src: t1.template;type:nunjucks">
</a-entity>
</a-entity>
t1.template
<a-entity id="id2">

t2.template
<a-entity id="id3" myComponent="x:4">
<a-entity>...
<a-entity>...</a-entity>
</a-entity>
<a-entity>
Entity components are displayed in the screen as required. I now want to remove the entire id1 when user clicks on any of the 4 component in id3. My component code is as below
AFRAME.registerComponent('myComponent', {
schema: {
x: {type: 'number', default: 0}
},
update: function () {
//set some attribute for entities inside id3
//adding event listener to id3.
this.el.addEventListener('click', function () {
setTimeout(function () {
var categoryEl = scene.querySelectorAll('#id3');
totalCategory = categoryEl.length;
for(i=0;i<totalCategory;i++){
categoryEl[i].removeAttribute('myComponent');
removeAttributeCount++;
}
}, 1500);
});
},
remove: function () {
//To check whether component is removed from all element
if(removeAttributeCount == totalCategory){
var id1 = this.el.sceneEl.querySelector('#id1');
id1.parentNode.removeChild(id1);
}
}
});

swift 4.0: Overriding 'prepare' must be as available as declaration it overrides
I was trying to integrate Apple's ARKit example app into my app. As ARKit is only an additional feature, so I need to support lower versions of iOS. I added @available(iOS 11.0, *) tag to all the ARKit example app classes...It almost works except this 1 error: "Overriding 'prepare' must be as available as declaration it overrides". Any idea how can I resolve this issue ?

Aframe React dynamic string value
Just trying to get my head around using react and aframe together with the spread operator etc.
So I have an Entity using Meshline
<Entity meshline="lineWidth: 20; path: -2 -1 0, 0 -2 0, 2 -1; color: #E20049" />
I'm trying to make that path string dynamic with 2 objects i.e. something like
buttonConfig.position = {
x:config.position.x-3,
y:config.position.y+3,
z:config.position.z,
}
lineX = {
lineWidth : 20,
path: {...config.position,...buttonConfig.position},
color: '#ffffff',
}
But that's obviously not working because I get a
TypeError: value.split is not a function
How do I turn that object into a string of values via AFRAME/React? Or am I trying to be too clever here and should just build the string? | 00

the best practice to integrate arFragment (sceneForm) with existing Fragment APP
We have been working on adding AR features to our existing APP for a couple of months with limited progress. Very excited to read the recent development from google on sceneForm and arFragment. our current APP consists three Fragments and one of them will need AR features.
It looks straight forward to us,so We replaced the Fragment in our APP with arFragment. The build is successful and stopped during running with little information for debugging. any suggestion on the proper steps for us to upgrade from Fragment to arFragment? or maybe I missed the points of arFragment here?
in order to show the problem without for you to go through our length code (yet valuable to us), we constructed a dummy project based on the sample project from Google: HelloSceneform. Basically, we changed the static Fragment to dynamic Fragment. Only two files are changed and two files are added, which are attached thereafter. The modified project can be built successfully, but stopped when starting to run.
Thank you
Peter

How to get value of JArray dictionary by key
I have this json string:
[
[
{
"Antibiotic after diagnosis":[
"Azithromycin",
"Ciprofloxacin HCl",
"Ampicillin Sodium"
],
"City":[
"Tel Aviv",
"Jerusalem"
]
}

[
{
"Antibiotic after diagnosis":"Azithromycin",
"City":"Tel Aviv"
},
{
"Antibiotic after diagnosis":"Ciprofloxacin HCl",
"City":"Jerusalem"
}
]
]
I deserialized this string:
data = Newtonsoft.Json.JsonConvert.DeserializeObject<List<object>>("*json str*");
JParameters = data[0] as JArray;
Debug.Log(JParameters["Antibiotic after diagnosis"]);
But when i run the code it crashed on the line (Debug.Log(JParameters["Antibiotic after diagnosis"]);) with the following error:

Running Oculus Unity Sample Framework
Are there some pre-requisites to running the Oculus Sample Framework in Unity? I start with a new project, add the package from the store, and that's as far as I get. 51 compiler errors, mainly relating to missing OVR* namespaces.
Also "AssetImporter is referencing an asset from the previous import. This should not happen.". I thought the idea was that a sample framework would just work?
