content: Hi Klaus,i tryed to PN you but your inbox seems to be full.No, these lenses are not compatible straigth out of the box and there is no adapter readily available. You can adapt them but this requires to remove at least the front part of the housing as the back focal length or working distance of those lenses is rel. short. You have to get them pretty close to the detector and this is not possible with the original housing of the TE camera(s).I did a relatively simple adapter for a FLIR 36mm lens to the stock TE-Q1 which may be for sale in the near future (together with the TE-Q1+) as I did an 'upgrade' ;-). A 50mm lens with the same mount is also available and should work with this adapter as is. One of those is currently on sale on ebay too. But be aware that due to the different F-number the factory calibration is not accurate anymore with either of the suggested lenses.RegardsToni

content: Thishttps://www.ino.ca/en/products/3-14-microns-infrared-camera-microxcam-384i-mlwir/is an MLWIR imager. That means it covers both medium-wave and long-wave IR bands. It's passband is 3um to 14um. Yet it uses a standard VOx microbolometer array. So I'm wondering, what material is the lens made out of, that allows such a wide passband? It can't be germanium, because that is only good for 7-14nm, and is used with standard LWIR images.

However, does it also cut the transmission in other areas? Or does it leave it at the ~45% value?Any idea what the transmission properties of an uncoated silicon window is? I'd be interested to see how that compares to uncoated germanium.

content: Hi, I have yet to see either of these in the flesh, not sure I understand the big(ish) price difference, but the TG167 seems more suitable for Auto-electrical fault finding. I am using my hacked E30 at the moment, but its more suited to indoor close up pcb work than outdoor / garage use.Has anyone been able to compare them side by side? Is the smaller FOV worth the approx. AU$200 price difference?Thanks.

content: I'm trying to stitch together Thermal image pictures. I'd like to stitch the raw (14-bit/16-bit) files, not downmapped 8-bit image, produce a 16-bit stitched image, and then do mapping on that.Microsoft's Image Composite Editor can do 16-bit processing, so hey - I generated .TIFF files with 16-bit, and it's supposed to calculate as 16-bit. Sometimes this works - when i export the panorama as TIFF, I get a 16-bit TIFF. But most of the time, it silently drops it back to 8-bit which is a pity. Anecdotal it worked when the camera mode was "pan" instead of "rotate" but i don't think it's really related. The official forum unfortunately is dead and all people who were publicly associated with the tool have left Microsoft and now work for Facebook apparently.Has anyone successfully used ICE for this and can tell me the magic incantation?

Analyzing images from a drone acquired using FLIR TAU2 camera - Page 1

content: Hello All,I am thinking of the best and easy way to analyze 1000 images acquired using Tau2 640 camera from a drone (One sample image is attached). I tried to get the raw image and use the equations in the exiftool forum to convert it to temperature but I had no success with that, I am using matlab to view the images and do the image stitching but my main goal is to have something from the images like temperature and correct them for atmospheric conditions. Any suggestions would be helpful? Thank you.

author_rank: Frequent Contributor
timestamp: August 09, 2018, 02:39:33 pm
content: The image you attached is an 8-bit image, i.e. the 14-bit raw data has already been converted to 8-bit, likely by either linear mapping or histogram equalization (or a mix of the two). Unless you happen to have the meta-information to recover the original histogram, there's no way to recover the temperature, as there's no information of what "white" and "black" corresponds to.The 14-bit data can either be "radiometric flux" or "TLinear" (seehttps://www.flir.com/globalassets/imported-assets/document/tau2_product_specification.pdf), and the computations are different depending on the mode.

The only thing I know that the images are acquired using Tau 2 640*514 resolution mounted on a drone. I think there should be an option to get another format of the images from Tau2, not sure and still need to check.Currently, I am thinking of a"not very accurate method" to get temperature is through taking some reference temperature measurements on ground and relate them somehow to intensity appeared in the images (0-255) and then apply regression equation for the whole image to get values of temperature per pixel.

content: Hi all,I am hoping to get some help from you guys with my radiometric Tau2. I am a total dumb around the context of electronics so I appreciate your patience in advance.Briefly, I am trying to extract the radiometric (digital data) per pixel of a recorded video (something like breaking down a SEQ or CSQ file). Tau 2 does not have the video capture mode built-in the GUI so an external video/frame grabber must be used. I am using a Photon replicator board which converts the native 50-pin Hirose connector on the camera to a 30-pin SMATEC (pictures attached) and increase the Tau 2 native voltage from max 5 v to max 24 v. FLIR provides an optional expansion board for converting CMOS to Camera Link. But I don't have this piece.Now to the problem: Can anybody advise on any alternative for extracting digital data from the current connectors (either 50pin or 30pin) and what framegrabber to use?Many thanks,Sia

Unfortunately, I don't have the knowledge to help you, but we eventually went down the ICI route, who produce a backboard for the Tau2 to get radiometric data out of it.FLIR told us we'd need the cameralink and sdk to get anything useful from it.

I was thinking of using an LVDS external frame grabber considering that LVDS data output is already there at the back of camera (if Im correct actually as i am seeing all the LVDS and SD pinout at the backend). So (of course again if Im correct) I was thinking to get 19 pin of HDMI arrangement and send them to a LVDS frame grabber such as UFG-06 Nopea HDDP (attachment)https://www.unigraf.fi/products/video-test-hardware/ufg-06-hddpI have no idea whether what I am thinking is correct.

content: I have. It sometimes seems to happen shortly after I change a palette or image mode. However, other times it happens when I'm just viewing the image looking around at stuff, and not changing any settings. At first I thought it had to do with motion maybe wiggling the USB connection lose for a moment, but it's also happened when I'm holding it perfectly still. The app itself doesn't lock up. I can still navigate the menus, but the camera stops sending video, so the last frame sent to the camera remains displayed indefinitely. This can be fixed by unplugging, and then plugging back in the Seek Thermal camera. Note, this is happening on my phone with the official app, not the result of me using it on a PC with 3rd party software.Anybody else have this issue? And if so, has anybody figured out the cause of this bug yet?

content: Quote from: Spirit532 on July 18, 2018, 05:39:36 pmI'm not sure, but I believe so. I remember that it usually sounds like a partial shutter activation. When the shutter works normally, it sounds like "click click". When it locks up, it sounds like "click". If the app worked correctly, it would simply send a reset command to the device. Also, do all phones provide the same power stability (part of USB standard)? Or do different phones provide more stable power during high current events (like the solenoid activating to move the shutter)? I wonder if I put a micro-USB extension cable on it, modified with a 1000uF capacitor across the the power rails of the USB cable, if that would do the trick of providing more constant power? A 1000uF capacitor would be able to provide a burst of higher current during shutter activation, I think.

content: so all of it basically.but be realistic. I want a camera for photography, not imaging. I do not care about your calibration, thermal accuracy or tools to make reports. I would prefer low noise, different exposure options, lens options, and most improtant, resolution of at least 0.5MP. Post processing raw data to stacking for even lower noise or higher resolution(or both), creative palettes and more control over histogram equalization, and real time processing that can be turned of, and stills gives you raw data.or an astro camera that gives you pure data in real wavelenghts, allows for long exposure and noise reduction, should work with a coated newtonian.and I want a rugged phone that has a basic camera with something like 240x320 resolution and a normal lens.

content: It would be kinda nice to have a modular form factor and changeable lenses at a moderate price. Oh, and open developer libraries. Seek seems to have a remarkable sensor in their Pro line, with way more pixels than what is coming out of FLIR. However, it looks like your options are "smartphone module" and "sorta clumsy tablet".The extreme cost of the sensors means that having a sensor module (IP68 or better, M12 lens) that can be used with multiple display units (Smartphone over USB for the cheapest option) would greatly improve things.(As far as I can tell, the "outdoor longer-range spotting-scope", the "drone camera" and the "engineering camera" are three pretty distinct and not-interchangable devices. Nobody can afford all three.)

If the image is opened through FLIR software as ResearchIR the logo disappear, so how to check if they are using some kind of masking the logo pixels with the around pixels. In addition, when the image is converted to tiff using exiftool using RawThermalImage commend it has the same 16 bit data as from ResearchIR is that mean the logo pixels is masked with the around pixels as well. And would that be applicable for the color scale in the image or it will be different.Thank you for reading the question

The teams current approach is to throw on about 10 thermo-couples onto the engine and record temperature data like that. I was wondering if thermal imaging would be a better approach to this problem. We are worried that the sharp temperature gradient of about 1700 K. Can this still be done? Which sort of camera would we have to use? Any advice is appreciated! Thank you! Please let me know if you would like any more details of our system. Will post results here if successful (:EDIT: I should mention we are primarily interested in the actual engine surface temperatures (which shouldn't exceed 200 C) not so much the flame. I am worried the flame will make data acquisition hard.-Ali

That should be your best bet.

content: I guess you are not expecting 1700°C on the rocket body but for the plume only but 1700°C gas temperature will never translate to that high reading on a thermal camera due to very narrow emission compared to a black/grey body (as the rocket body is) and transmission too. This is especially true if you are going to use the LWIR band (8-14µm) but to a lesser extend also in the MWIR (3-5µm).So if you are only interested in measuring the rocket engine solid parts temperatures you might be fine with most any reasoably good thermal camera that is good up to 500°C. Totally different story though if you are interested in exhaust gas temperature or even radiance measurements.

content: Sadly the only two options I know of that work with the FLIR Vue are Pixhawk and the system you referenced.The creation of a specialist GPS adapter for the FLIR VUE took someone some time in development, so sadly the price will be high. It may well be based upon a ATMEGA AVR microcontroller but that is a moot point as creation of the software loaded on it will require in depth knowledge of the FLIR VUE communications port and functionality. Sadly I cannot help with those as I have not worked with Mavlink or the FLIR VUE.300+ Euros may seem like a lot if money, but how long will it take you to develop such an interface ? For 300 Euro's you get a proven system that may be used immediately.The world of Drones is expanding fast. They are still relatively expensive for survey capable models and the FLIR VUE PRO is also an expensive product. To a surveyor, 300 Euro for the GPS interface would not be that much of a surprise. Hence that is the sort of money being asked for the interface. A good quality, light weight, self contained Serial GPS can cost 100 Euro alone.None of this solves your problem though, and for that I am sorry. You may get more help with this challenge on the better Drone forums that deal with creating and modifying Drone electronics packages. There are already Drones with built in support for the FLIR VUE so maybe DJI will provide support in the future. Sadly that could be a long wait however.In your position, if the need is justifiable, I would buy the module you referenced and and consider it all part of the thermal surveying costs overhead.Fraser

It is a departure from their normal camera format, but there is a huge market for preventative maintenance thermal camera surveillance. Such 'box camera' formats also find their way into CCTV and science applications. FLIR have had an extensive range of 'box cameras' thanks to their acquisition of Indigo who specialised in thermal camera miniaturisation. Maybe it is time for FLUKE to spread its wings a little as its Raytek acquisition some years provides experience of industrial non-contact equipment monitoring using thermal sensors.Pricing will be interesting and expect to see >30fps available as such ban be a requirement for industrial process monitoring.Fraser
