Seek Thermal Compact PRO - thermal imager for Android
Zaytseff, lay out pzhalsta picture, which gives
the program "ThermoVision_JoeC" - the number of dead pixels on the matrix, the button [Show DeadPixelMap].
It is curious to compare how much better-worse the quality of the matrix.

I also think myself such a device. I looked on the Internet, there is an aliexpress, people are happy with reviews (https: //www.aliexpress...ad0&priceBeautifyAB=2)

I roughly understand the meaning, but not exactly. As I understand it, this function is for correcting dead pixels, and the details are not very clear.

zadig-2.3.exe(4.92 MB)You need to install the program, connect the device, then install the driver for your device. In the program on the left, select seek Thermal, click connect below, or even lower the DeathPixelMap button.

the introduction
For the most accurate capture of thermal images, I use point-to-point calibration (description in English) for each pixel, this process is called Mapcal, because the result is a map with calibration values.
You need 2 evenly heated surfaces, one of which is as cool as possible, and one as warm as possible.
For quick tests, a wall is usually sufficient as a cold link, and a palm is like a hot link.
It is not very important what surface temperatures have exactly, but it is very important that they are uniformly warm, or at least a part in front of the camera lens radiates the sensor evenly.
calibration
To capture raw camera data are accepted. First, the “cold link” is recorded. That is, the camera should be aimed at the object of the cooler.
It then produces a camera image that ideally displays the measured value for the link characteristic of each pixel.
If this still image of the camera is saved, a “hot link” is executed again.
Then 2 camera images are available. The next step will be the calculation, the success is usually the same automatically.
DeathPixelMap:
DeathPixelMap is first created (it will be a “Cold Reference” “taken for this”, it’s basically just a binary array ... either the pixel is good or bad. All pixels whose reading is in a certain range of numbers are considered good first, all the rest (shorts or open spots on the Sensor, for example) are marked as bad
immediately GainMap
Now the change is detected for each pixel (which was not marked as bad), as a result of which the “hot” values ​​are divided into “cold”, and the result is the so-called gain value. If it is too large, the pixel is wrong, if it is too small, if it is is defective or “blind pixel”, both marked as bad in
Deathpixelmap
Now all (good) pixels of the “cold” frame are calculated together, forming the average. Then each pixel is subtracted from this average and an offset map is created.
As soon as 3 maps are created, the function will be ready and Mapcal can be used. How Mapcal works:
The original image is captured by the camera.
each pixel is multiplied by the corresponding pixel value of the map with the extension
For each pixel, the corresponding value of the offset map pixel is calculated.
then all strongly marked pixels are replaced by the average of all nice neighboring pixels.
The result is a camera image that only needs to be colored for display and with which you can measure temperature.

if in your own words but uses
search for dead pixels (snapped into maximum brightness) on a uniform dark background (cold wall),
search for dead pixels (snapped into minimum brightness) on a uniform light background (warm hand),
and 2 point calibrationtwo-point-calibration
Considers dead pixels on average on live around,
and for the living, it does two-point-calibration,
and eventually builds an offset map for all pixels.
on this amendment map, then the desired image is corrected.
left-handed66, That is, you need to connect it to your computer, or what? And where is the hole then take this? I have never seen such connectors on computers)
you just don’t have to push the camera there at once, expensive toy, check the adapter first, the hell of them knows these Chinese people, they can lash the wires too. plug in to check out some old flash drive, which is not a pity, through the OTG cable, if you did not smoke and see the computer, it means everything is normal and you can cling to the camera.
I made myself such an adapter. of 2 moms microUSB. (it was a pity to cut off the whole USB laces, but no half-dead ones)

poking around with ThermoVision_JoeC came to the conclusion that the program is interesting and worthy.
: roll: download-try "virus-free"
Download-try, "screw sharing" is not yet interesting - the author is not up to Android. A laptop with a thermal imager to carry - is nonsense. Like the "Windows" tablet to adapt to this "program". The version is the only one, without viral panic, from Windows. ;)

Something I did not understand the essence of this statement. Either the author is against Windows programs, then he himself lays out one of the versions for Windows, and without need. What for?
I recently purchased a compact. The toy is interesting, but the incorrect display of low temperatures confuses me, and it’s stated to -40 ° C. How do you think it can be calibrated ...? I read somewhere else that developers will finish the software and it will be available for third-party developers, so that third-party programs will appear.

about calibration in itSeek Thermal Compact PRO - thermal imager for Android (Post andr_r # 69507079)
after calibration, the picture is better, sorry not for long, it warms up and floats away again, and we must again calibrate everything with a new one.
and it is difficult to find a uniformly cold surface, with a warm, simpler one.
I would like to know for myself whether the developers will make their software better?, and can anything be done with floating calibration from heating at all? can the radiator stick on top? somewhere I have already seen a photo of this option.

On the xr model how to increase the viewing angle? Are there any lenses?
by lens materials
we need lenses from certain materials - germanium, silicon, zinc selenide and others. ZnSe optics are used to focus the laser
hereA companion writes about optics, only he tried macro photography (the viewing angle decreases), does not write about increasing the viewing angle, there are other lenses needed or even probably somewhat convex and convex. Who is engaged in optics or remembers it better - will tell.
I also came across something on this topic on the bourgeois websites, but right now I won’t find it and didn’t save it. And there, too, everything about macroshooting was there.
Why do you need to increase the viewing angle? there and so like the rules. And from the increase in the viewing angle, the resolution of the picture does not increase, everything remains the same, only more. :)

It will be much easier and cheaper to sell and get the regular version. Or add some money and take the PRO version, so as not to feel defective.

People, on the raccoon 8 the camera is not recognized. I downloaded the application, connect the camera with the help of the native Samsung adapter Usb C and nothing happens. Tell me where to dig
plag, Seek Thermal is not compatible with most Samsung devices. Most likely you will have to use another device.The native adapter from sams8 + does not work and some kind of Chinese too, took in know-how for 400 rubles. with rope adapter, earned. Phone sams8 +, pro seek.

Replaced the phone on the Meizu Pro 7 Plus (model M793Q with firmware M793H) works fine, I use an adapter that the seller puts together with the thermal imager.
