Adding custom palettes to the Flir Exx - Page 1

content: HelloI have an idea inspired by the software posted in this thread:https://www.eevblog.com/forum/thermal-imaging/palette-generator-free-tool-to-create-thermal-palettes-for-flir-tools/It is very nice to have additional custom palettes in the Flir Tools software, but wouldn't it be also nice to have those custom palettes directly in the Exx camera?I started digging in the folders of my Flir E60 and found the palette files in the system folder where also the appcore.d is located.I added the files of the palettes to this message.The content of a palette file seems to be pretty straightforward, the only thing is that the color space is YCbCr while the software outputs in RGB, but that can easily be converted with some coding.Here is what I think that the entries on the beginning of the file mean:stretch: Probably a measure of how aggressively the flir maps the colors to the temperatures, the RainbowHC palette has the highest value of all the palettes, so that would make sense.overflow: color that gets displayed when the temp is out of the high limit measurement rangeunderflow: color that gets displayed when the temp is below the lower limit of the measurement rangeabove/below: thats likely the displayed color for the above/below range featureisotherm: colors for the isotherm featureI don't know yet what major, minor, edit and method mean, but that should not be too critical now, I can just try the values of the iron palette.What do you all think, if I create another palette file with exactly the same structure and put it in the same folder would the camera recognise it? I looked around and found no other entries in config files about the initialized palettes, so maybe the Flir automatically adds them to the menu once they are in the folder. If that is not working I would have to modify an existing palette.Is there any additional risk involved in adding additional files to the system directory (except of course the standard risk when just replacing files via FTP)?Thank youBestPhoenix

content: Do not know about Exx but in E4 the palette file names are hard coded. You can only change an existing palette file's content. If a net new palette added with a new file name, the camera will not recognize it.

A few questions about Indigo Omega IO module - Page 1

content: Hello, my name is Frank. I have lurked on EEV for a little while but just registered recently. I have a question about what IO module is compatible with a Indigo Omega core. I purchased a Indigo core with the environmental housing which afforded me a nice sturdy enclosure with what looks like a germanium view port and most important of all, a breakout board that has the now obsolete connector made by JAE Electronics, Inc. part no-DA1B018H91 which is referred to as the "camera connector", this is soldered to a small pcb with a standard looking molex connector then passing the signal/power/data along to what looks like a lemo connector on the back of the enclosure. So I have one connector for the camera side, I am still in need of another breakout board to build a cable, or if at all possible find a factory interface cable to connect the camera to the IO module. First I need to make sure the IO module I just bought on ebay will work with the Omega core, I have some pics of the IO module and connector used on the breakout board which is labeled with the correct pin-out for composite video and power as I understand it. I would be grateful for any help with this question, i'm just getting my feet wet with thermal stuff.

content: Do you need to use the IO module for anything in particular? I’m not sure about the IO module compatibility, but if you don’t need to configure the camera settings you could just run power to the camera and pull the video from the breakout board you’ve got with it. It’s gonna be hard to find a cable with the camera connector on both ends for the IO module I’d think.Congrats on the purchase, I had been eyeing that listing with the nice environmental housing as a potential thermal camera for my truck! Hope you get it working well for yourself!

content: I would like to use the rs232 functions to play with settings, if I can get a good enough image with it I would probably use it for diagnosing component level problems with pcbs. If the resolution or color gradient doesn't work for that I was thinking of either using it in my car or if there is enough space inside the enclosure, mount a small lcd to make a thermal monocular that can be mounted to a rifle. There is a seller who has a few of these for sale, I believe his username is codex0, hes who I bought mine from.

It looks like you need a focal plane array made out of neon tubes.This is not the method that requires a second THz source, it looks like it can be used to generally look at THz power, probobly from a home made glow bar.The idea is to create some kind of aparatus in the lab that could be used to measure THz power level or presence, in a cheap way.here is the RF forum version thread, hopefully more focused on diodes and stuffhttps://www.eevblog.com/forum/rf-microwave/cheap-thz-experiments/

content: From the FLIR press release> widely deployed and real-world-proven Boson thermal camera moduleso where exactly is it used? I have seen it a bunch on UAVs and at least one research application as well as a few Monoculars. Yet there don't seem to be any thermography applications for it. Like the only FLIR product this ended up in was the Scion.Overall this rerelease just seems like an additional binning bucket. They already had levels for "consumer", "professional" and "industrial" with different levels of NETD and dead pixels. So this "plus" suffix is just finer step. If pricing scales equally it will be 5k+ for 640, as radiometric or 320 versions weren't mentioned for the new variant. (And framerate isn't mentioned, but it's not an additional cost for the other models)We have had discussions about how noise measurements are done and what they mean quite a bit. Mind you it's usually done with with f/1.0 lenses, and the first party lens options for the Boson are all f/1.0 - but I have seen OEM options using slower combinations. The figure of 20mK does seem really low - but then again the Boson had a bunch of issues with noise, so maybe it's all processed using the chip?I highly doubt that one of these will ever be something I own, but if they managed to make it a competitive option we perhaps see it in more applications and products - on the high end.

content: It reads to me that, between FLIR and Teledyne (who have their own experience with VOx do note), the basic sensor pixels have been improved.The major issue (a couple of years back now) was that nobody left at FLIR knew much about running the ex-Movidius processor, and with the ownership changes from Movidius to Intel FLIR did not qualify for support either, being too small a customer.As such the Boson software was effectively stuck at what could only charitably be called a 'version 0.4' level and development was very slow. A lot of unresolved issues were limiting use in several applications.Not a problem for ambient use in drones/UAV though, which is where the Movidius processor itself is aimed (via DJI the drone designer).Maybe alterations to the signal path, offloading to a host, could been done to bypass the shortcomings in Movidius software ?Equally a lower basic pixel noise would allow lower system gains and so allow increased dynamic range for a still respectable 50mK NeTD.Bill

content: I'm sure I'm misunderstanding your question.How many pictures you can download to a PC is limited only by the PC's storage capacity.Remote operation using Atlas SDK seems like a huge project to me, but if you're an experienced SW developer I guess it's doable.I would investigate existing solutions before starting such a project.I have a Flir C5 and use Flir Tools for post-analysis of pictures, works fine. No remote control though.Seems like Flir Tools is obsolete now, Thermal Studio Suite is the new thing.

I can take pictures also of the inside.The problem is quite annoying, as i can use only half of the screen for sensitive measurement. The offset is only 1 or 2°c, but enough for change the colors.Someone that know how works the ir detectors, have a clue on what sort of problem can be?Thanks!

content: If the transition isn't "pixel sharp" it could be the shutter flag somehow got stuck halfway at some point.Either once at factory calibration and then you get bad prerecorded correction tables.Or it's always getting stuck during operation --> there you might fix it mechanically.I can't really imagine a chip with a power rail coming from strictly different pads for each half, so I don't think it would be that.

I'm quite curious to know what can be.---EDIT---Actually, i need to correct myself. With a better inspection of the raw bmp saved image, i've the impression that the ccd camera and the infrared camera images are mixed in an analog way, so it's not exactly "split pixel". Need to check all the ic's on the boards to verify this.

Cairns Viper 320x240 Thermal Camera RS232 - Page 1

timestamp: December 12, 2021, 06:32:39 pm
content: Hello,I had an old Cairns Viper 320x240 thermal imaging camera module sitting around in my lab for a while and finally had some time to mess around with it.From what I can tell it is a decent quality camera from the early 2000s that shoots 320x240 at 30 FPS. It outputs standard NTSC analog video on pins 19 and 20 of J5. The module its self comes from a firefighting unit which I found through this forum post:https://www.eevblog.com/forum/thermal-imaging/rs232-protocol-software-for-older-thermal-imaging-modules/Of which the product brochure can be found here:http://www.fire-tics.co.uk/others/cairns_viper.pdfWhile the camera does work I would like to see if I can get some of the onscreen functions such as the temperature scale to show up. In an attempt to configure the camera I found out how to communicate with it. On J5 there are two RS232 ports running at 115200, 8 bits, no parity, and 1 stop bit. Port one is connected to pins 3 (tx) and 4 (rx) and port two is connected to pins 5 (tx) and 6 (rx) of J5. Port 2 appears to do nothing while the other, Port 1, gives boot information as well as brings up a command line interface giving this message at each boot:QuoteUnfortunately this is where my luck runs out. I have tried almost every command I can think of and each time the camera responds with:QuoteAs you can see above the camera appears to be running Windows CE Kernel for ARM. Using the internet I found a list of commands but once again had no success in receiving a response. To talk to the camera I am using a RS232 level shifter with an Arduino UNO acting as a serial pass through.I do not have experience with Windows CE so I was hoping that one of you guys would tell me what stupid thing I was doing. Does anyone have any suggestions on what commands to send? Any help at all would be greatly appreciated.13

Upgrade recommendation from FLIR i5? - Page 1

content: I have a FLIR i5 at work that we bought sometime in 2014 or 2015. It works ok but the lack of a tripod thread mount is an issue, as well as minimum focus distance and a couple of other things.I would like to buy a newer unit that:- is at least 160x120 resolution- covers the 0 C - 200 C range- has good accuracy (+/- 2 C in the 50-150C range preferred, but I'll take what I can get)- has a camera thread mount- has minimum focus distance of 50cm or less- has flexible image triggering options -- just a manual trigger is not very appealing. I'd like to either trigger a new image via USB/Bluetooth from a PC (example: Python script that runs and asks for an image every second for 10 seconds and then every 2 seconds for 20 seconds) or stream images to a PC where I can somehow pick off the ones I need and save them- costs less than US$1200 (goal of less than US$800)I like the way FLIR embeds the temperature data in the JPEG itself.I'm looking at the FLIR TG267 which looks good except for what appears to be a lack of flexible triggering.

content: You might want to take a very close look at the TG267 specifications. I believe you will discover that it is more of a visual IR thermometer and not a Radiometric thermal camera. There is a significant difference between the two. The TG range are a collection of hybrid devices that have combined a standard single pixel IR thermometer with a non Radiometric Lepton imaging core. Why they did this I do not know. Not the greatest idea to come out of FLIR.

content: I do not know your operational use scenario but the remote control requirement pushes my recommendation towards the Dianyang Technology CA-10 that offers PCB analysis with a PC controlling the camera and capturing the image data. The camera is intended to offer the user decent resolution and measurement accuracy combined with a good quality stand design and versatile image analysis tools. Take a look at my review on this forum. The camera may be removed from its stand and mounted on a tripod or other support system if desired. The system comes in well within your budget and the analysis software is included for free. The cameras manual focus range is approx 20mm to infinity.https://www.eevblog.com/forum/thermal-imaging/review-dianyang-technology-ca10-circuit-board-thermal-analyzer-repair-rd/Without knowing your practical usage needs it is hard to make other recommendations.Fraser

Same with ThermViewer which is supposed to be better. However I have issues with it. It keeps crashing and locking up on phone and tablet, and the view is upside down.What software should I really stick to with this thermal camera?

content: I was looking at TEquipment.net and saw that there are two new brands of thermal cameras that seem relatively inexpensive. For example, the Sonel KT-400-19 has a 384 × 288 resolution and can measure up to 1,200° C but costs less than $5,000:https://tequipment.net/Sonel/KT-400-19/Building-and-Industrial-Thermal-ImagersEven better, the Fotric 348A-L25 has a 640 × 480 resolution and can measure up to 1,200° C but only costs around $6,300:https://tequipment.net/Fotric/348A-L25/Building-and-Industrial-Thermal-ImagersThis makes them much cheaper than similar cameras from FLIR and Fluke. They also both look good on paper. However, I couldn't find any reviews for these cameras. Do they actually live up to their claims?

content: I found one review of the Fotric 348A on YouTube:https://youtube.com/watch?v=cUvKErt5JFEHowever, the reviewer only went over features and uses, and didn't say anything about pros and cons.TEquipment also posted a review not too long ago:https://facebook.com/watch/?v=4450710698314268The second review is much more detailed. According to the reviewer, the Fotric 348A shows more useful information and has a faster focus while FLIR's MSX is "smarter." Of course, I can't expect the reviews to be too negative because TEquipment is a selling these cameras as distributor.

timestamp: November 18, 2021, 04:43:39 pm
content: I am not aware of any firmware alternatives for this unit. It uses a non-Radiometric FLIR Lepton 2.0 imaging core so no Radiometric based options are open to you. The TG165 is a ‘visual thermometer’ and uses a conventional IR thermometer sub system for its temperature measurements, so not much to be upgraded in that department. The colour palettes offered on this unit are few, namely 2 (Monochrome and Hot Iron) so there may be an upgrade avenue there to provide more colour palettes. Apart from that I cannot see much else that could be upgraded. This is likely why you have not seen alternative firmware.Fraser

So I was getting a drink in the break room when I smelled what seemed to be something burning. I was a little concerned and alerted our office manager. She looked around and went to touch the appliances to see if any of them were overheating. I went to grab the camera from the lab and did a quick scan around the room. It was definitely reassuring to see that the FLIR E60 didn't pick up anything that could be an electrical fire.So yeah, thermal cameras are awesome. Too bad they aren't cheaper.

To program it for the Argus 3, refer to the first photo. Press and hold the two power buttons (labelled here 1 & 2) until the LED blinks. Then press (left power) (vol up) ( + ) (vol up) (vol down). LED should give one long blink.Menu functions can now be accessed on the Argus 3 using the buttons identified in the second photo. You need to point the remote at the small aperture to the bottom left of the monitor.

Infiray C210 charging issues - Page 1

content: Hello! I recently bought an Infiray C210 camera, and while the camera itself seems to work fine, it's charge VERY slowly.I got it out of the box and it would not turn on, I thought this was odd, as devices with lithium batteries normally arrive with a decent charge in them. So I put it on charge for about 40 mins, and then I was able to to turn it on, but it only had 1 of out 4 bars/<25%. I thought this was also odd, as it states the charging time as 4 hours when the device is off, which should give you 11 hours usage. I put it back on charge, but this time overnight.Turn it on; only 2 of 4 bars! 7 hours on charge should give you more than 50% battery.I then tried using different cables and chargers, and put my USB power meter to use to see what current it was pulling. Across 6 different USB chargers(all rated 5v and 1.0a or higher) it refused to pull more than 0.37a at around 5v.Other devices with the same cables and chargers pull much higher amperage, so it's definitely the device.Left it on charge for 8 hours yesterday, and 15 hours today, and it never got past 50%.I did find that if I have the camera on and plugged in, it pulls around 1.6a, but I don't know how much of that is actually charging the camera since it's powering the device too...I'm discussing the issue with the seller on Aliexpress as I believe it to be a faulty unit. After explaining the above, they have suggested I try to charge it to 100% while it's powered on, due to the higher current. It is currently on 3 bars/75% after being plugged in for about 2 hours, so maybe that'll work? Unless the battery suddenly comes good after a full charge, I'm not confident it's a long term fix!Anyway I wanted to see if anyone else on here has a C210(or C200) and if they had any similar issues? (Even with a different device!)Oh, this is my first thermal so I'm only going by videos and images online, but from what I've used of it(before the battery got too low) the images this thing gets are great!I have hardly used the normal camera in the mixed modes as the detail on the thermal is so good! The images look much better than the similar priced offerings from FLIR and SEEK!

Sofradir Atom 640 Core - Page 1

content: I got this core mis/unidentified but a match as best I could tell, it's marked on the exterior with only ATS100020 and a serial number. I got it in hand, powered it up over USB, didn't see any analog video output, but was able to get digital video over Camera Link through a Bitflow Karbon CL4-SP and modifying an Atom 1024 configuration file that the SDK ships with. The trouble is, it also seems to be in fixed gain mode, so while the image looks crisp and 60Hz, it is very low contrast. From the Atom 1024's manual, I should be able to issue commands to the core over the Camera Link connection's serial link, but I have been unable to get the core to respond so far. Sofradir (now Lynred) also seems to never had its AtomGUI control software available for download, and at least so far my requests for the configuration utility have been left unanswered. I've also seen the "D*STAR" software mentioned as their go-to analysis software, but google seems to ignore the special character even when searching with quotes, so I've come across nothing really to try and get a hold of that (though undoubtedly an expensive bit of software), so if anyone has an idea of where to find control software or commands/formats to try over a serial terminal I'm all ears. In the meantime, how about a bit of a teardown:The microbolometer appears to be a Pico640 by ULIS, unknown whether it's the newer Gen2 or the S version (S version please!), but presumably there was also an original base version. The core has an Artix-7 FPGA and the IO on the rear panel are all handled by what seems like a switchable add on board - I know there are LVTTL variants of a lot of their cores, so this is probably the equivalent of the VPC on FLIR cores. The case shape and IO configuration doesn't match the higher resolution Atom 1024 or their older PV640 based cores (but man it would be awesome if it had a PV640BB sensor.... 2-20um sensitivity is crazy!)

So if anyone's got a copy of the Atom GUI they can pass along (I believe the Atom 1024 control software is identical), or any documentation or information on the serial command protocol used, it would be appreciated. Otherwise, I've got another serial protocol guessing project on the list somehow.

content: That all depends on where the overlay graphics are applied.Many imaging cores provide their own graphics overlay and some can be reconfigured to remove such graphics. Other camera designs use whatever graphics are provided by the core plus camera manufacturer supplied graphics overlays that are applied to the image output of the core. It is sometimes possible to obtain a clear, or relatively clear composite video image at the core output before any additional graphic overlays are added.Cores are configured using hidden menus, command line instructions to a comma poetry or manufacturer specific configuration utilities that are not usually public domain.the command sets and utilities for some cores have got into the public domain however.Fraser

content: Quote from: Logan on September 21, 2021, 02:54:42 pmThe other route is that some of the cores mentioned have their own 'clean' output reasonably accessible, so can be taken off before the camera builder adds all the stuff you do not want.So for example the BST core produces a clean analogue and 10 bit digital video. In general the camera builders then took the 10 bit digital, added their overlays and then D-A and/or output the result on screen.2000AS was the same, but moving on to the 3500AS and later the overlay functions could be performed within the core so you'd need the core control software to fix it not a bit of Kynar wire.

content: it's different palettes and different histogram equalisation mappings.The imager produces just a monochrome image which doesn't have a lot of contrast. But stretching the signal out to fill the 8bits of greyscale and using a fake color palette gives you results that show the difference in signal more.
