7. Guide for Scanning
Scan objects
In order to ensure model quality, the scan-suitable objects are divided to 5 types according to theirdimensions shown as the table below.
50cm<Largeobjects<200cm

25cm<Medium
object<50cm

15cm<Smallobjects<25cm

Face

Body

Feature type○ Geometry:
This scanning mode is ideal for capturing objects with intricate geometric details and irregularshapes. However, it may not be well-suited for objects with many planes or circles. This mode isparticularly recommended for scanning materials such as plaster portraits and handmade items.
○ Texture:
This scanning mode is best suited for objects with rich texture features and intricate color patterns.
However, it may not be effective when scanning objects with solid colors or repetitive textures. It ishighly recommended to use this mode when scanning objects such as tables with wood texture.

Texture mode is very useful because it can be used to scan various object when it is allowed to affix ordraw markers on the surface of the objects.

It is not recommended to highlight reflective (metal or plated surface), translucent and transparent(glass cup, glasses) objects. Such scanning objects need to be dusted (liquid foundation, flour, drycleaning shampoo, developer) and then scanned. It is not recommended to scan objects that areeasily deformed (such as soft bags, animals).

Not recommended object

High reflective

Transparent

Live animals

Accuracy option
Fast: Faster scanning, but the accuracy in this mode is relatively lower than with Hi-Quality
scans.
Hi-Quality: Higher scanning accuracy can be obtained. However, the processing time for will be
relatively longer.

Color map
○ Map/Color: The final processed result of the model is attached with a color map(Creality Scan
can only export color objects in the .PLY & .OBJ file formats).
○ No map/No Color: The final processed model appears as a solid color without any color
information, only the shape information is captured.

8.Guide for APP :Home Page:

The main area of the home page displays a list of models scanned in history. The list shows the scan resultsof all completed optimization and subsequent steps. Top Bar Functions:●

Setting Button: Setting Page Entry;
In the setting page, information of scanner is delivered
to help better utilization. Meanwhile, any question can be asked on Facebook when Creality icon isclicked. Page Entry Search Box: Used to retrieve the corresponding nameof the model;●

List Order Switch Button: Used to switch the list order, which is divided into two types: fromthe latest to the earliest and from the earliest to the latest.

Bottom Bar Functions:●: Used to display the connection status of the scanner,with red indicating disconnection and green indicating a connected device. Users can click on thisarea to view the device's serial number.
Device connection function● Configuration Function :In this area,
users can access the scanning configuration options and view the current selection. Clicking on it will
expand and show specific configurations for selection. Refer to the configuration description for more

information. Start Scanning Function: Used to initiate scanning based on

the parameters set in the scanning configuration item. Please ensure that the scanner is connected
and has sufficient storage space before starting the scan. Preview

The preview phase mainly provides RGB images/depth images, IR images, and real-time point clouds forpreview, alignment, and judgment of the current point cloud quality. The RGB/depth preview window and
IR preview window provide nine squares for alignment of the scanner's field of view. It is recommended tokeep the scanning portion in the center area of the preview window.
The IR preview window supports adjusting the IR exposure method (automatic/manual, default automatic).
The exposure level of the IR image affects the integrity and quality of the point cloud. The red portion of theIR window indicates that the area is overexposed, and it is recommended to manually adjust the exposure
pull down to prevent it from displaying red. The blue portion of the IR window indicates that the area isunderexposed, and it is recommended to manually adjust the exposure pull up to prevent it from displaying
blue. The adjustment effect can be viewed in combination with the RGB/depth preview window for depthchanges. Generally speaking, the more complete the depth is on the scanned target, the better the quality ofthe point cloud is.

Overexposure

Normal exposureUnder-exposure

The RGB/depth preview window supports adjusting the RGB exposure mode (automatic/manual, default
automatic). If you find that RGB is overexposed or too dark, you can appropriately adjust the exposure level.
This preview window also supports the display of depth images, which can be superimposed on RGB images
by adjusting the depth translucency.

Depth diagramScanning

The main body of the page is a 3D rendering area, and the scanning phase is used to display a point cloud.
The point cloud is divided into two parts, one is the current frame, and the other is the scanned point cloud.
The current frame in red indicates poor point cloud quality, and the current frame in green indicates
successful tracking and registration. The scanned point cloud is displayed in a quality chromatographic modeby default. When displayed in orange, it indicates that the scanned part is of poor quality and requires
repeated scanning. When displayed in green, it indicates that the scanned part is of good quality and meetsthe quality requirements for generating the model.
The 3D rendering area supports interaction during the pause phase, and its interaction methods are as
follows:

Single finger rotation

Two-finger press and move (withhaptic feedback)Two-finger zoom in/out

Area AThis section mainly displays the current process stage. Click Next to proceed to the next stage ofprocessing.

: Back to the right button, click to initialize the object rendering scale and display it in the center.
//: The display mode switch button can be switched to three modes: solid color display
mode, color display mode (map needs to set as color ), and quality mode. Click to switch the current
mode, and the quality spectrum mode is default.
/: Plannar-clipped mode/planar mode: The current frame point cloud in the deplanar state will
be removed from the plane, that is, the background plane will not enter the scanned point cloud during
scanning. It can be used to scan small and medium-sized objects placed on a large plane. The planar state
will not remove the background plane.

Other scanning suggestions
How to judge whether the scan is sufficient:● Judge whether the scanning target is complete, and conduct multi-angle scanning.
● Judge whether the color of the scanned point cloud has changed from red to green as a whole based on
the quality spectrum mode.
Once satisfied, you can click Next to perform point cloud optimization.

Optimization

This stage is used to optimize scanned point clouds and display them. Point cloud optimization andsubsequent stages automatically save model related results.
The 3D rendering area is used to display the model. The display mode supports solid color display mode,and the delivery method is the same as described in the scanning section.
: Share button. After point cloud optimization and subsequent steps, the scanning results can beshared.
The inset picture above shows the configuration items for the next meshing step.
If Holefilling is on, the small holes will be filled with neighboring data in order to ensure the completeness ofthe model.
If Closure is on, the meshed model will be enclosed.
The meshed model can be saved as your choice in formats: stl, obj, ply.

MeshThis stage is used to demonstrate the model after meshing. If use choose no color mode, this stage is the laststage of the process.

10. Tips
1. Scan targets

Suitable object: human face, parts, sculpture, cultural relic, garage kit, toy, shoes, body.
Unsuitable object: super large object such as wall, room; micro parts; jewelry; ductile objects;
Specail treatment objects: transparent objects, metals, high reflective objects
2. Target size

Typical size: 5cm×5cm×5cm ~ 150cm×150cm×150cm
If you are experienced in scanning, you can challenge scanning larger or smaller objects.
3. Scan distanceMove the scanner at a perfect distance to your target according to the prompt.
4. Scan backgroundLess objects are expected in the view of the depth camera except your target.
5. Tracking lost
When tracking lost, return the scanner to the previous position and stay for 2 seconds until tracking recover.
6. Exposure

If you want to obtain a better model, you should adjust the exposure yourself to avoid red or blue partappearing in IR image which means overexposure or underexposure respectively.

7. How to obtain a high quality model?
Use USB 3.0 or above port;

Hi-Quality mode should be chosen;
Move your hand or rotate the turntable slowly during scanning;
Keep perfect distance according to the prompt during scanning;

Adjust the exposure yourself to avoid red or blue part appearing in IR image;
Keep scanning until all the parts you want are adequately scanned (the quality map turns green inquality mode);
Set smaller resolution when optimize the point cloud.

11. FAQs
1. Can the scanner be powered directly by a mobile phone, without using a charging handle?

If the mobile phone supports USB3.0 Type-C port, then it can power the scanner directly. However, thisconsumes a lot of power and we recommend using the charging handle for a stable power supply.
2. How to avoid tracking loss?
Return the scanner to the previous correct position and hold on for 2s to retrieve the image.
3. What is the scanning frame rate of the scanner?

The scanner provides depth images of 30fps, supports a scanning frequency of 30 fps theoretically.
However, the actual scanning rate depends on the calculation power of the mobile phone or PC
involved in the process. In practice, the scanning frame rate can be lower than 30 fps. We recommend
using a device with high calculation power to achieve optimal results.
4. What system configuration is recommended for the scanner?

For mobile phones, it is recommended to use smart phones with USB3.0 interface and running memoryof more than 8G, such as Samsung S22, S23, etc. For computers, it is recommended to use i5 or above
with USB3.0 interface.
5. Does CR-Scan support USB2.0?
The scanner supports USB2.0, and the scanning frame rate will be limited by the lower data transmission rate.
In order to adapt to USB2.0, the scanning accuracy will also be reduced and some functions may be forbiden.
6. How long can the charging handle support continuous scanning?
It can support more than two hours of continuous scanning by directly using the charging handle. Generally
speaking, the scanning time of small and medium-sized objects is within 5min, that is, the charging handle
can support 20 to 30 small and medium-sized objects.
7. How to restore the connection when the mobile phone scanner is disconnected?
Plug the USB cable on the handle of the rechargeable battery again.
8. Some Android phones show disconnection when they are disconnected from the scanner for acertain period of time. How to restore the connection?
If the device is disconnected for more than a certain time (for example, 10 minutes), some Android systems
will automatically turn off the OTG connection, and the device status is always offline. The device can beconnected only after the OTG switch is turned on in the Android system.

9. What are the influences of scanning effect?
① The model itself is too thin or too narrow with holes. There are reflective and transparent parts on themodel. ② If there are other objects around during preview, remove the obstacles and rescan.

10. What are the limitation of scanning frame rate ?
① The configuration of computers and mobile phones is too low, ② USB3.0 interface is recommended.

11.What do we do if "few point clouds" is showed?
If the exposure time is too long or too short, you need to cancel the automatic exposure and manually
adjust the exposure time.

12. The USB2.0 is detected while USB3.0 was connected.
Usb3.0 is compatible with USB2.0 and has four pins in common. if the usb3.0 is pluged in slowly, the foutcommon pins are detected before the additional pins of usb3.0, the PC or smartphone will reconize theconnection as usb2.0. The solution is to plug in usb3.0 quickly again.
13 How to deal with the warning "Invalid data" ？
If the "Invalid data" warning constantly appear, please check the scan objects setting. While themedium objects are being scanned on a turntable and large objects option have been chosen, thescanner will give the warning. We suggest you rescan the target using medium(or small) object option
and aim the scanner at the prominent part of the target texture or slow down the speed of scanning.
