TE-Q1
 
Heat shadow on concrete. 4x speed



Ants on ant hill. Sorry for low quality. It turned out worse after uploading to youtube. I find the close up focus impressive.

Gah! That heat shadow instantly made me think of nuclear shadows from the WW2 Japanese bombings.

Hi guys,
I tried to get some nice shots of the sky with broken clouds - all panoramas and quite large. I did not expect the stitching to work as good as it turned out due to quite a bit of wind and moving clouds. But I am really pleased with the results.  ;D

Camera: TE-V1
Lens: Ophir 35mm f/1.4
Subject: town, landscape, cloudy sky (sun in image1)
Processing:
 - structured panorama shots with 10x8 (image 1+2) or 15x5 (image3) images in serpentine movement (8°/6° fixed position increments)
 - 8 images averaged per position
 - raw export to .png with varying gamma correction on almost full dynamic range (except sun in image 1)
 - stitching with Microsoft ICE
 - post-processing using PS (brightness/contrast - all images) and own tools for contrast limited local histogram equalization (images 2+3)
 - 50% resize and conversion to .jpg for forum upload (original images are 5MPix+)
It's so big, detailed, beautiful and noise free!  :scared:

Thanks, I just remembered my (empty) Flickr account and uploaded some of the images in full resolution there. Link to the wide pano in 4407x1307 pix: https://flic.kr/p/RWJdKr

TE-Q1
Cutting with circular saw
3x speed
Custom color palette added to gif file.


Ash from pyre. I thought the TE-Q1 was supposed to be limited to 150°c.

I think I read something about reaching around 280°C already in the threads couple years ago. I think back then the higher temperature values were only available in some set of data. And even these days, the specification's limit might be given on the basis of how high it can give accurate enough values that they can hold the accuracy specification.  But -12.4 to 309.3, huh..?

In the new SDK code the temperature tables go from -30C to 260C (and clip there if input values would result temperatures outside that range), but those might be without ambient correction or whatnot. The curve starts to be quite flat by the high end clipping point, so there probably isn't much more range left above even if it was not clipped, but I'll probably check it when I start coding my own version.

So i managed to get an improved version of Seek Thermal (standard non-xr version) for 170$ (used, sh).I think it's a 2017 version, it has a manual focus ring, which is a pretty big deal.Compared to what i was used to seeing in the old version with fixed focus, which was more of a smudgy mess, this is a huge improvement.It can also focus up to 3cm.For this kind of money, it packs quite a punch.

Phone used : Samsung Galaxy S7 edge

App : Seek Thermal Android App

Thermal Sensor Resolution : 206 x 156

Software version 2.1.5.2

Image Processing Software 2.5.6.2

That is surprisingly good quality from seek compact!

Obviously not my own work, but the latest SpaceX launch has some nice TI footage of the first stage coming back to land:

Do you have any TE-V1 pictures from a low contrast scene? Like indoors in a garage or a basement. Or in a forest after sunset or during an overcast day.

A few longer range tests with Seek Thermal Compact (non-xr).Manual focus ring does its job very well  :-+

Sensor Resolution:206x154

Software used : Seekofix 0.4 and ThermoVision_JoeC_1.0.0.3 (old 2016 version, as i can't figure out how to make newer versions work  :'( )

The occasional black box in the left up corner is the shutter info from ThermoVision_JoeC

Do you have any TE-V1 pictures from a low contrast scene? Like indoors in a garage or a basement. Or in a forest after sunset or during an overcast day.

I just did some testing for Joe-c's software and here is some indoors image with ~4°C temperature range in the full FOV plus the lens is only f/1.4 (compared to the stock f/1.0). This should increase the noise by a factor of ~2x.
Additionally post 243 on page 10 has two outdoor images of very distant landscape - one image is a single raw frame, the other an average of ~60 images for noise reduction. The lens here was f/1.6 - so even more noise to be expected ;)

The second image is cleaned up a bit using bilateral filtering - removes quite some noise but keeps most of the noticable detail.
The last image is a calibrated one using the stock TE-Q1 (not yet fully thermally stabilized) to show scene dynamic - the Q1 image has full range of ~5°C but the coldest spot is the upper right corner not visible in the V1 image.

If there is interest in more detailed data I can dig-out my DIY Dual-Blackbody and dial in some pretty close temperatures like 0.5°C and take some snaps with the stock lens to get a better impression.

edit: Small side note - the doors on the cupboard are glass - as is the door/window to the right and you can see a double reflection of my shoulder in the lower right corner of the rightmost door.  :o

As we are about it: I got some new SBC toy, namely a LattePanda 432 that arrived last weekend. Couldn't resist to throw on my software and plug-in the TE-V1 and take some snaps.
Works nicely so far an I like the 7" touch screen - this should make some nice portable IR recording box.  ;D

Image of wood heater taken with a Thermal Expert M1.

CSV capture, converted to PNG (ThexConvertGUI-0_3) and upscaled 400% with ImageJ (Bicubic interpolation).

Thermal scale was from 27 to 372 degrees Celsius.

Therm-App Pro, 35mm f/1.2, Thermviewer, Microsoft Image Composite Editor, Paint Shop Pro X

Note: the original monochrome image is 3x the size of this - about 18,000 x 5,750 (~100 megapixels).

That is cool seeing how LWIR illuminates. I noticed the same thing from a masonry stove. Things were lit up both in IR and optical light. :D
