content: When you visually see gas it's most probably not really a gas that you are seeing but an aerosol. Most commonly water droplets or soot.Both radiate pretty well in infraredIn addition some gases do radiate themselves but that would be weak next to the aerosols.

content: Which is which?One of these images is a black hot thermal, the other is a B&W visible light image. To the trained eye it'll be fairly obvious which is which but I wonder whether the casual observer will immediately be able to do so.No inference should be taken from the relative sizes of the images; I did some scaling to make the objects appear roughly the same size. Both images are crops from the middle of a larger image. The thermal camera recorded a span of about 30°C so it wasn't exactly a noisy image, however the visible light camera frankly isn't that good and was struggling a bit.Device used: FLIR SC-660 thermal and built-in visible light camera. Both images fairly similarly processed from in-camera JPG using Paint Shop Pro X.

content: I've always said black hot is as close as you'll get to visible light in black and white. The above comparison proves that pretty well. The bottom image is easily identified as the thermal but only because of the "blushing" on the door showing a temperature differential and the IR reflection on the latch hasp. The "cold" screw heads stick out also. I'm thinking they may be reflecting the sky.

But I've got a prusa, and I didn't upload any of the videos cause I was test printing with polycarbonate and was running into Y axis crash issues that were stopping the video every so oftenMaybe next time! I haven't seen a great long-term temperature differential with many layers of print, but that first molten hot layer looks great coming out of the nozzle.

content: Barbecue at cooking temperature, peaking around 800°C.FLIR SC-660, standard lens. Off-camera JPG, plus radiometric TIFF extracted with Exiftool and adjusted to taste in Paint Shop Pro.The scene was hot enough that the sensor suffered temporary burn-in, however the automatic NUC quickly sorted that out. I think this is the first time I've used the camera on its 2000°C range.I did try pointing my Therm-App at the same target but it simply couldn't cope: it virtually whited out and there was no detail in the hot bits. No surprise there, as the Therm-App isn't rated for anything like that sort of temperature.The first image below is the full radiometric JPG: I'd be interested to see what anyone else can do with it, for example changing the linearity and/or employing a pretty palette.

content: Writing (a lot of) data to a 512GB Kingston SD card with a cheap USB 3.0 card read/writer.Therm-App Pro with ThermViewer for 1280x960 originals, stack of ~20 images in Registax 6, minor processing and crop in Paint Shop Pro X.If you turn the image upside down you can just about read "Kingston" on the card in the dark (hot) section nearest the reader and "512GB [C10 symbol]" in the middle. And if you squint hard enough, there's a USB 'trident' logo in the light blue rectangle on the USB 3 (extension lead) socket.The second image is an uncropped and unprocessed original, straight off the camera. Although stacking ~20 images like this reduced the noise, there wasn't actuallymuchnoise in the image to start with.Edit: Added X-Ray of the card. Image quality isn't all I'd hoped it to be, but I'll see what I can do to get a clearer shot of it in due course. The main issue is that my X-Ray system is set up for objects much larger than a SD card - think more in terms of X-Raying a DSLR, with generous margins all around - and the optical system will need slight adjustment to focus in on a closer area. I know I'm at completely the wrong end of the spectrum here for thethermal imagingforum, but hey...Edit II: Added somewhat higher resolution X-Ray made with microfocus source. I'm still working out how to use the machine (I don't have a sensor plate for it) but already the images are, I think, arguably better than the Scanmax can manage.Edit III: Added another X-Ray of the same SD card made with a Faxitron 20 microfocus cabinet system. The difference in clarity is like night and day. I expect to get even better images in due course once I've found my way round the machine a bit, calibrated it and so forth, but that's not exactly a thermal imaging topic!

content: Effect of different palettes.(click image for Flickr page or download full size 2617 x 1980 5MB PNG originalhere)Here is the same thermal image taken with the camera set with four different palettes: clockwise from top left are Iron, Black Hot, Rainbow and White Hot.It's often said that Black Hot (top right) is the closest you'll see in the thermal spectrum to a black and white visible light image. The car is very dark grey and the sky (reflected in the windscreen) was clear (=cold) so that certainly holds true here.All of the original images were made with a Therm-App Pro 640x480x25Hz thermal camera with 19mm lens, ThermViewer driver software (which provides superresolution to 1280x960), then Paint Shop Pro just to blur out the registration plate (which showed up incredibly clearly) and composite the four images. They were saved as PNG from the camera and haven't been compressed.You may just be able to make out my driving spectacles, which I left on the bonnet whilst I took these images. They let me see a sparrow at 1000 feet but are absolutely useless at anything approaching arm's length. My arms aren't long enough to hold the Therm-App far enough away!Taken at a motorway services car park near the England-Scotland border on a fine, sunny late September day. (My passengers had wanted to stop for a comfort break and, apparently, there was a queue - so I had a few minutes spare).

Here is a self portrait I did during some testing for a monthly photography competition. It is shot on a MIRICLE 110K 25um pixel camera with a 32mm f/1 lens. I captured the composite out via a USB frame grabber and saved a few stills as .bmp then change that to .jpg and used Palette Generator and applied the FLIR iron palette ripped from a Lepton image. I will include the greyscale image as well so you can the what of a perceived different it makes.the top right is the FCC flag partially stuck again - that requires a simple fix... or I switch lenses altogether.

I started to remove the lens from the VGA sized core, but that was unsuccessful so far, the lens seems to be in some kind of housing and now there final two accessible screws are stripped.This was an idea completely out of the blue. I remembered to have shot about the same angle on my phone a year back. that was with my DIY lens attachment of the new broken lens. I had to manually adjust the levels and the shutter shadow is very present. getting the VGA core will only fix half of the issues. full digital access and RAW output is my long time goal for the next year. tomorrow my brother has a lot of people over and I will gather some shots of people and play with color. doubt I will get the shutter fixed or the core freed in time.-stiched from video in ICE, paint.NET color adjustments, Palette Generator with FLIR iron palette. resolution is incorrect both times.old post(reference):https://www.eevblog.com/forum/thermal-imaging/thermal-imaging-gallery/msg1887413/#msg1887413

content: Re CAT S62: There isa Lepton 3.5 in side and that has a shitty lens. It is fixed focus so somehwere between 85cm and 5m. However there are other issues with it's implementation - VividIR is a really crude sharpening algorithm that FLIR employs and doesn't give any details about. It sometimes gives better images, but often only hides the issues with such a low resolution core. the further issue is that no matter what image you shoot, thermal only, MSX, alpha... you will get upscaled to VGA resolution (while you are an 16th of that). And it is the blurry type of upscaling that makes this very useless past "detecting something", if you manage to see if between the 7hz. It is not any noteable improvement over the CAT S60 with a Lepton 2.5 from just the experience. The further issue is that 3rd party apps like ThermalCamera+ By George Friedrich isn't supported for the newer leptons anymore (CAT S62 or even FLIR One Pro(which the CAT S62 has integrated)). Otherwise the phone is baller I am just sad about the wasted space for none exsisting bottons, no headphone jack and grounded screen corners for what ever reason ever.But to keep this on topic, this is a gallery so I will post something. Here is an image shot with a real VGA core(MIRICLE 307K-25) and 32mm f/1 lens. It's captured via analog out and saved with a ImmersionRC PowerPlay. As this is monochrome with AGC within like center 70% and <2000kbps the quality is awful and I am seeing interlacing artifacts all over the place.

content: Quote from: Simon1983 on September 21, 2020, 11:17:10 pmThermal is often like that: sharp edges can be really hard to achieve.There are so many factors working against one in terms of achieving good picture quality (compared to a mid-range cellphone visible image).1 - resolution - this is a big issue: you just don't have many pixels, and they are all (necessarily) processed nearly to death in order to get a usable image. A mid-range 320x240 camera has 0.077 megapixels but no self-respecting cellphone boasts anything less than 10 megapixels - that's a factor of130 times more resolution.2 - lens quality - whilst itispossible to create optically perfect lenses at LWIR, it can be horribly expensive. Commodity thermal cameras use the simpler lens designs (eg fewer elements) and are often constructed with cheaper, lower performance materials produced to lower precision. That all helps to keep the device affordable. One of the lenses I have for my FLIR SC-660 lists at about the same price as a small car (and it's notalldown to what I call "FLIR Tax"). Also, thermal camera lenses are normally as large-aperture as possible, within the cost constraints, which means the depth of field is limited. For fixed-focus cameras the manufacturer sets the lens up for roughly the hyperfocal distance and hopes for the best.3 - wide frequency range - this is a subtle corollary to (2) and, in effect, means you haveno chanceof getting sharp images: typical LWIR cameras respond to a wavelength range of 7µm to 14µm, a 2:1 range. It is simply impossible for a simple lens to bring all of those wavelengths into sharp focus at the same time. The best you can hope for is that your subject will emit the majority of its energy in a moderately narrow range, but the nature of blackbody radiation (which we're looking at) means that's unlikely to happen. (In visible light lenses you get 'chromatic aberration', perhaps most often noticed as purple fringing on edges. These days even phone cameras have pretty well-designed multi-element lenses that minimise the effect, but applying the same level of complexity to a thermal camera lens is difficult-to-impossible, not least because there is no LWIR equivalent of the subtly different glass types used in visible lenses).4 - processing - touched on in (1), but you really do need to understand that thermal imaging sensors are a very different beast from visible light cameras; adjacent pixels on a thermal sensor can have wildly different characteristics. These are mapped individually (pixel by pixel, sensor by sensor) by the manufacturer and for each sensor an individualised 'non-uniformity correction' data set is created - basically a big table of data that describes the offsets, non-linearities, drift characteristics and scaling differences of each individual pixel. Every pixel in every frame from a thermal sensor has its output tweaked according to the corresponding data points in the NUC table. And then there's noise reduction: thermal sensors are noisy, not least because they are responding to infinitesimally tiny variations in temperature. If you have a visible light camera with adjustable ISO, imagine running it at its highest ISO settingall the time: that's essentially how a thermal camera lives its life. For any given sensor type the only practical way to reduce itsactualnoise level is to use a larger-aperture lens. I have germanium lenses as wide as f/0.75; my widest photographic lens is f/1.4 and I believe the widest aperture 35mm camera lens in common production is f/0.95 (Nikon 58mm). Stanley Kubrick famously used one-third of the world's supply of ultra-wide aperture f/0.7 lenses (Carl Zeiss Planar 50mm) during the filming ofBarry Lyndon- but I digress...Sorry I've warbled on so much (and I've probably missed some important stuff) but hopefully this goes some way to explain some of what's going on. Reading back over what I've written I realise there's a lot more that could be said - for example, I mentioned the hyperfocal distance in (2), whereas it usually isn't appropriate to focus a thermal lens there because the low resolution of the sensor means that anything further than a certain distance will be too small for the sensor to detect, so it makes sense to focus a little nearer than hyperfocal ... and so it goes on.

content: Quote from: bap2703 on September 22, 2020, 05:53:07 pmNo I didn't forget that. They are not as slow as you suggest. The frame rate is determined primarily by the readout hardware (ROIC) and back-end processing.The ultimate limiting factor is probably the thermal time constant of each pixel. Many microbolometer datasheets publish this figure - for instance in the Ulis Pico384 Gen2 it is quoted as <10ms, meaning that the microbolometers would be happy at ~100 frames per second. Other parts of the sensor limit the practical output to of this device 60fps. But exactly this sensor is used in several <9Hz thermal cameras: like I said, it's the back end that primarily sets the speed.There are a number of microbolometer-based thermal cameras that operate in the hundreds of frames per second range. FLIR offers a LWIR camera that runs 1280x1024 resolution at 180Hz (the X8500sc SLS) and also other thermal cameras that quote29,000 frames per second. But we won't see any of those at hobbyist prices anytime soon.

Sure nothing prevents you from working at higher frequency, you just lose signal.That flir camera is called "SLS" because it's not using microbolometers but photodiodes.Photodiodes are much sensitive and faster because there's only one fast process involved: photons are converted instantly to electrons-hole pairs that you just collect to count them.

The difference in usability with ThermViewer and the Therm-App Pro is startling. Whereas the Exynos 8890-based 2016 phone struggled with the necessary processing and often dropped and/or corrupted frames, the newer Exynos 900-based device delivers silky-smooth images and video. It just reminds me what a darn good camera the Therm-App Pro is and makes me sad that Opgal no longer make them.(Addendum: I quickly got used to the genetically modified aerial that grew on the side of my head to let the Bill Gates vaccine chip communicate with the secret Microsoft satellite.

Note the image is reversed (mirrored) from the original image posted by Ultrapurple.Edit to add: Changed contrast-stretch to 2%x0% to minimize blowout at top end. Also flipped image to correct orientation.

timestamp: August 13, 2021, 09:32:30 pm
content: frenky, Ok that kind of makes sense, the minimum value in the file is 1832 and maximum is 3303, so that's a minimum temp of 18.32 deg C and maximum 33.03 deg C. Wonder why they didn't just use floating point values. Would have been a smaller file.Edit to add: Those temperatures may not actually be the target temperatures. See this post from Stackoverflow:https://stackoverflow.com/questions/56695676/how-to-open-a-txt-file-of-ir-temperatures-as-an-image-in-matlab-or-other-analysiand specifically the following:"edit, since writing this I've found that the output .txt file of temperatures is actually sensor temperatures which need to be corrected for emissivity and background temperature to obtain the target temperatures. (One way to do this is to use the software which comes free with the camera to create new output .csv files of temperatures and use those instead)."

content: Perhaps this should move to a new thread.It is worth noting that (at least in the case of the Therm-App series) the 'temperature' of the pixels depends on the lens used. This particular Therm-App Pro was purchased with that specific 35mm lens and, as it's averyearly unit, I suspect Opgal may have taken a little more care over calibration than may normally be the case.There is no overriding reason that the pixel data should be an accurate representation of the actual scene temperature, though it may be a happy accident that it works out that way. I'll have to make an image of something like ice-water beside boiling water so we can see what happens. And if I do it with different lenses we can maybe learn more.New thread started:Deer photos and Therm-App Pro data. Let's leavethisthread for pretty pictures, as was originally intended.

content: Okay, back to making pretty pictures.While manipulating the data to make details visible is certainly useful, I like to start by getting all the thermal details with a distinct color palette. While in some cases this produces some cool isotherms I recognize that in many cases it makes a rather "busy" image as well as noisy. I do like the "grass" look here, though, even if it is noisy.Someone who prefers gray scale only might instead apply the entire gray scale to the background & then do the same to the deer & then combine the 2 to get the following. Not much more detail in the deer, but noticeably more in the background.In similar fashion, taking the green from my distinct color palette & applying Seek's "Amber" palette to the deer yields brown deer on green grass (which I think looks pretty cool).As far as simply applying a single palette, I think my favorite is the standard "iron" palette:And applying Seek's "HiLo" palette gives us deer on snow.

It was still a little on the warm side so I decided to frighten it with a thermal camera.If the board has bits running at ~120°Cwitha heatsink, I can only wonder at how hot it was gettingwithoutthe additional dissipating surface. Whodesignsthese things?

content: Inspired by downtodoI propped up a small steel ruler and looked at it with my FLIR SC-660 (and close-up lens mentioned earlier) with two different palettes.Although colourful, I don't think my results were anything like as interesting as the image by downtodo.The third image was made without the auxiliary close-up lens and taken at the point of closest focus with the standard 40mm lens. It's interesting to see the rather narrow depth of field and also to compare the field of view.Withthe close-up lens the field of view is about 30mm, or roughly 2 pixels per mm (500µm per pixel). Without the lens the FoV is nearer 240mm, about 2.5mm per pixel (2500µm per pixel).

This algorithm does not use machine learning.Certainly such methods can help recover some details, but it took ~12 hours for my computer to finish the reconstruction. Although >7 hours are spent on optical flow estimation, which should be much faster on GPU. Ma, Ziyang, et al. "Handling motion blur in multi-frame super-resolution." Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition. 2015.attachments are one of the original video frames and the processed (3rd iteration) imageEdit: Just realized the input frame size is huge... It seems Xtherm app is saving the videos with 1408x1068 resolution for some reason or stupidity. The reconstruction should be much faster if we feed correct 384x288 frames to the program.Second Edit: Tried to use thermviewer app to capture the video and it can be saved correctly in 384x288, however, the result looks horrible after the reconstruction with the parameters in the original code. I'll try playing with the parameters when I got time.
