I've got liquid ballast in my compact tractor tires, always wondered how full they were.

Hi all

new here.

i used my TE-Q1 to look at some chips sending data in my home automation setup. Mainly a Lora RFM95 module and an ESP8266 sending data.

The lora footage is not very good since the heat is very low but its possible to see the heat propergate thru the chip. The esp looks much more interessting on how the heat radiates from the traces in the PCB

take a look at the video

@agh768 - welcome to the group, and thank you for posting such a fascinating first image.

I got similar results when I looked at the multi-core processor on a Raspberry Pi. You can actually see different parts of the chip 'light up' as a benchmark exercises different numbers of cores and facilities. The links contain videos and notes.



Interestingly, unlike your excellent example I didn't see any evidence of the heat being conducted away via the PCB. Maybe that's why this version of the Pi had a reputation for running hot, and has been superseded with one that has a heatsink bonded to the chip.

Can you see the little bird?

it does look really smooth, is that really 9 hz?

Yes it's 9fps.

some testing of my TE-Q1 with 19mm lens after sunset.

some testing of my TE-Q1 with 19mm lens after sunset.

So many users of the TE-Q1 here. What does the extra lense do? More field of view? Nice "green iron" color palette you made there. The pictures with cars is that after sunset too? Since the car shadows are cooler than the surroundings it looks like the sun is still up. When the sun is down shadows and enclosed areas tend to be warmer than the surroundings.

The 19mm lens is basically the most "tele" official option for TE-Q1, i.e. "zooms in" the most (and most narrow view). Not that much of zoom, really, but still.  Also, the most expensive lens, like 350€ at https://www.thermalexpert.eu/english-1/shop/lenses-and-accessoires/

Quick comparison of three Therm-App cameras and a FLIR SC660

1st image - Therm-App, 384x288, unmodified 9Hz, 19mm lens, Thermviewer, superresolution to 768x576

2nd image - Therm-App, 384x288, 9Hz camera modified to 25Hz, 19mm lens, Thermviewer, superresolution to 768x576

3rd image - Therm-App Pro, 640x480, unmodified 25Hz, 19mm lens, Thermviewer, superresolution to 1280x960

4th image - Therm-App Pro, 640x480, unmodified 25Hz, 35mm lens to give same FoV as 19mm on 384x288 cameras, Thermviewer, superresolution to 1280x960

5th image - FLIR SC660, 24mm lens, x2 upscaled to 1280x960

--- Edit

6th image - Argus 3, photographed off screen, due to the limitations of the camera's screen this image does not exactly represent the 320x240 resolution of the thermal sensor

7th image - visible light view of scene


Images 1-4 were made with ThermViewer set to its subjectively 'best' settings (essentially the same for all four images) and post-processed in Paint Shop Pro to give a more pleasing greyscale but are otherwise as-shot.

Could you make a comparison between Therm-App 384x288 and Therm-App Pro 640x480 with an indoor scene where there is little thermal contrast? The kind of scene that results in noisy pictures.

[eKretz]

I'd say the FLIR walked away with that one. Just a little more expensive though...

I second that motion!  Something like full grayscale spread over 1.6 degrees C; certainly no more than 3.2 degrees C.  Same for the FLIR, but you might need to go lower than 1 degree span.

Images taken with a Thermal Expert M1

Captured as CSV on Android smartphone, converted to PNG with Frenky's ThexConvertGUI-0_3 application (code changes required to make it work with the M1) and finally up-scaled 400% using ImageJ with Bicubic interpolation.

Here's my lunch (pizza and garlic bread) heating up in the oven. 

Thermal scale was from 20 and 120 degrees Celsius.

Will do. Any  preference as to lenses? I have 13mm, 19mm and 35mm available. 19mm on both cameras gives exactly the same level of illumination (of course) but different fields of view.

Probably the fairest test is 384x288 with 19mm f/1.1 and 640x480 with 35mm f/1.1 - the lenses are the same aperture and, as seen earlier, have the same field of view.

Agreed, but the field of view is secondary in my opinion, since noise is the issue of concern.

would it be possible to export/upload png instead of jpg? the SC600 image above  shows quite a few jpeg compression artefacts (but still looks sharper to me than the Therm-App ones.) it also looks a little like there are sharpening algorithms applied to the FLIR one?

Folks - this is wandering off the 'gallery' topic so I'll start a new thread specifically on comparing Therm-App cameras. I'll update this post with the details when I have taken the relevant images and established the thread.

In brief answer to @polar yes, the FLIR images do come out fairly heavily compressed-looking, even though I set the save quality to best in the menu system. I have yet to investigate importing the images into FLIR Tools or other software in order to get better-quality saves.

Ultrapurple, not sure if your flavor of .jpgs works, but you can try your luck with the steps outlined here to get a raw image: https://www.eevblog.com/forum/thermal-imaging/flir-e4-thermal-imaging-camera-teardown/msg342072/#msg342072


this is a gallery so you deserve some images.

here are two vertical panoramas of a building I shot. It is nothing special and more like a test. They are shot with my phone and DIY lens. the pixels are upscaled by a factor of 5.66 and superresolution is enabled.

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. 

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+)

Those look great! Nice job.

It's so big, detailed, beautiful and noise free!

That is pretty awesome!  Gives an idea what a 20 megapixel thermal camera might produce...
