Great job, It compiled easily on my MacBook Pro running Linux Mint, and displays a great image from my P2 Pro.

Thanks

Great.  Please post or PM any issues that you may encounter so I can try to address them.

For those running Linux, you might be interested in the tuned-adm package.

It controls your PC's scheduling and thread frequency SpeedStep controls providing a lot of profile options.

I usually switch between "desktop" and "latency-performance". 

When regression testing with a long duration redirected stdin command script, "latency-performance" and unrestricted offline FPS (-fps 900), the "latency-performance" setting finishes the script [3-5]X faster.

It may also be useful for your general purpose Linux use and performance targeted projects.

So far I have Thermal Camera Redux working on the following Pis with the 2023-12-05 release of Raspberry Pi OS desktop 64-bit (Debian 12 bookworm):

  RPi 2 Model B v1.2       BCM2837      ARMv8-A     (64/32-bit)   4× Cortex-A53 900 MHz   CFLAGS='-mcpu=cortex-a53 -pipe -fomit-frame-pointer'
  RPi 3 Model B v1.2       BCM2837B0  ARMv8-A     (64/32-bit)   4× Cortex-A53 1.4 GHz    CFLAGS='-mcpu=cortex-a53 -pipe -fomit-frame-pointer'
  RPi Zero 2 W                BCM2710A1  ARMv8-A     (64/32-bit)   4× Cortex-A53 1 GHz       CFLAGS='-mcpu=cortex-a53 -pipe -fomit-frame-pointer'
  RPi 4                             BCM2711       ARMv8-A    (64/32-bit)   4× Cortex-A72 1.8 GHz    CFLAGS='-mcpu=cortex-a72 -pipe -fomit-frame-pointer'
  RPi 5                             BCM2712      ARMv8.2-A  (64/32-bit)   4× Cortex-A76 2.4 GHz    CFLAGS='-mcpu=cortex-a76 -pipe -fomit-frame-pointer'

Performance is very good on the pi4 at x4 scale, x5 slightly reduces the frame rate. It's especially good on pi5 up to x5, and still keeps the responsiveness and frame rate usable up to x7. It's very responsive on the others as well so long as you stay at 3x scale or lower, x4 is still usable with a frame rate ~20.

Well done 

I am trying to achieve the same on the RPi Zero 2 W
I have installed Raspberry Pi OS desktop 64-bit without trouble but keep running into errors when installing OpenCV

Do you have any advice on the install?
- Compiling the source on the Pi (cmake)
- Memory increased to plentifull with swapfile
- Have added the contrib modules
- Cmake on all 4 cores -j4

Would also be interested in your -D flags

Thanks!

The initial github release has noticeably improved performance on the RPi Zero v1.3 compared to the last version I tried on it, I saw FPS up to 16.9 with no HUD, 13.8 with the default HUD.
The early pre multi threading version does indeed perform much worse. I wonder if a single threaded version of the current release with the numerous performance tweaks and improvements would run better on the single core single thread CPU of the Pi Zero.

The optional flags are a very useful addition. 

Arrow keys aren't doing anything for me, I tried with two different keyboard, both were laptop style without a num-pad however. I will try again with a full size keyboard.

RPi Zero v1.3
Launch times consistently repeatable within 0.1 seconds (repeated at least 3 times)
- Offline 11.6s to display key bindings in stdout, 13.7s to display image
- Online 12.3s to display key bindings in stdout, 16.0s to display image, or 15.0s with flag -scale 1

- FPS noticably improved at 1x, including with duel window layouts and rulers enabled, though dragging rulers reduces to ~1fps
- No image artifacts

RPi 2 v1.1
Launch times consistently repeatable within 0.1 seconds (repeated at least 3 times)
- Online 3.6s to display key bindings in stdout, 5.2s to display image.
For comparison 3.7s and 5.9 with release 16.

- At 2x scale shimmering horizontal bands, similar to a poorly tracking VHS tape
- At 1x perfect 25 FPS, bands still present but far less noticeable, shimmering much less.
I will try to work out the best way to send a recording of this, creating a gif to post here lost too much detail to be of any use and I suspect video hosting sites like youtube would do something similar when they trans-code it.

Amish Tech,

Thanks for the detailed update.

RPi Zero v1.3:

- The 11.6s and 12.3s to printKeyBindings() is disturbing.  The only thing that is going on is argv parsing, a few variable declarations and opening either the camera or file.  I would guess the lag is opening the disk/device since neither invokes a data read until after printing the key bindings.  The initial GUI window creation is done next.  Loading from disk could also be an issue.  I assume you are starting the program from a SD card ?

I can add some startup timing stats to zero in on the worst offenders including the load from disk.

A single threaded -D flag is possible with some rework.  From the logs, the processing of the image sub-frame and thermal sub-frame are taking the lion's share of the time.  The 3rd thread is waiting idle most of the time.  On the PC, all 3 are pretty evenly loaded.  The 3rd column from the end shows that there is a significant amount of time waiting for threads to sync where a single thread would eliminate those waits.

The latest github release logs gives a more accurate picture of how long the camera reads actually take.  The "read n.nn" column looks fairly well.  Before, the read timing also included the waits on the camera's FPS rates.

RPi 2 v1.1:

Horizontal banding.  Have you tried using the "r" key to see if the banding shows up in the recorded .avi file ?  It might help isolate the problem if it shows up in the composited video/graphic image, or OpenCV's display.

If it doesn't show up in the .avi file, you might be able to use the Linux "peek" command to record a GIF file if peek is available on the Pi.

The 3rd last column waits appear more reasonable compared to the Zero 1.3, but it appears there is still some uneven thread loading with the image thread taking the longest.  I could swap some of the work loads between the thermal and image threads if the lag is in the rendering stages or dump some into the main thread.

I added some function pointers in the last release and was thinking about doing realtime smart thread loading by monitoring the thread stats and then swapping loads in realtime to balance the aggregate load based on hardware capabilities.

Also, the Zero 1.3 appear to take twice as long for OpenCV to show the prepared 1X frames vs the 2X frames on the Pi 2 v1.1, a factor of 4X slower considering the frame size delta.

How were the font and ruler displays at 1X and 2X ? 

Were they more or less legible than the December release ?

Was there any temp text-flickers ?

Thanks much.

[G28]

Another idea for the RPi Zero v1.3. 

I could reduce the resolution of the ruler drag.  Right now it is plotting 256 landscape points and 192 portrait points.  During drag, I could half or quarter that resolution and then return to full resolution at the end of the drag.

What is the frame rate of dragging just 1 text temp and just the cross hair of text temps without the line plots ?  If they are reasonable, decreasing the resolution of the line plots during drag will help.

Ah yes, I have been compiling opencv from the github as the repository is quite outdated and I read using apt might induce future problems when updating. (or if updating)

But thanks! that should get me started.

RPi Zero v1.3:

Yes the whole system runs from a micro sd card, I have two that I've been using for testing. The legacy 32bit Pi OS is on a slower class 4 16GB kingston card which I've used for the Zero v1.3 and 2 v1.1 while the rest of the 64bit models have been tested with a nearly new Samsung pro endurance 256GB U3 card. I'm going to have to borrow another one of those from another project and test again to eliminate the sd card differences. I have about a dozen cards for the RPIs now but still never have any spare

The legacy 32bit Pi OS is on a slower class 4 16GB kingston card which I've used for the Zero v1.3 and 2 v1.1 while the rest of the 64bit models have been tested with a nearly new Samsung pro endurance 256GB U3 card. I'm going to have to borrow another one of those from another project and test again to eliminate the sd card differences. I have about a dozen cards for the RPIs now but still never have any spare 

RPi2 v1.1

Recorded .avi file attached

Thanks for the feedback and .avi file.

PM's and test mods sent. 

The test mods also includes startup timing logs to see where the startup time is spent.

Note: I've just received the 'FAST_DRAG DRAW_SINGLE_THREAD' as I was about to post this message, thank you  Will provide feedback on it probably tomorrow.

I've cloned the slower SD card onto a faster card identical to the one I've used for 64bit models (purchased at the same time late last year so they shouldn't slow down due to wear). I overlooked the impact this could have as I'd incorrectly assumed the difference would be negligible for an app that's ~140KB compiled, but it appears to have improved things a bit, for RPi2 v1.1 especially.

These fps figures for online are all far better than I had expected as they feel like ~2fps because all the frames come at once and then it freezes for ~0.5s, unless you drag slowely and then it's a relativly consistent stuttery update rate. Perhaps the best option for weaker CPUs is to disable dragging things and have it click to position only?

x1 double 10.9fps dragging single temperature point around with status hud disabled
x1 double 10.3fps dragging both rulers around with status hud disabled

Perhaps the best option for weaker CPUs is to disable dragging things and have it click to position only?

With only 0.6 fps delta between 1 temp and both rulers, FAST_DRAG probably isn't going to make much difference.  Still like to see the results of the 2 new compile flags.

Yep, will add -DNO_DRAG=1 to optionally disable drag scrolling, but even without it, it doesn't stop the user from using the click jump-scroll method.

... as they feel like ~2fps because all the frames come at once and then it freezes for ~0.5s, unless you drag slowly and then it's a relatively consistent stuttery update rate.

That is odd because waitKeyEx( 1ms ) is only supposed to block for a max of 1 millisecond and then get blocked waiting for the next frame read to finish.  It appears as if imshow()'s are being stacked/buffered inside the OpenCV library (like printing buffered instead flushing buffers after each print statement). 

I am doing mouse debouncing to minimize unnecessary processing because there is only 1 composited render per frame, but OpenCV allows multiple mouse events per frame.  I only act on the last mouse move because there are no "tween" frames at fixed rates.

FAST_DRAG may speed up that stuttery update behavior.

Felt slightly less smooth at any given frame rate than I'd expect.

On my i7-9700 PC in offline mode and FPS set to "-fps 60" or higher, drag scrolling feels smoother than at 25 FPS. 

Part of what you are experiencing is 25 FPS.

Question, did it feel smoother in older versions ? 

The newer versions uses nano-sleep to stabilize FPS instead of using waitKeyEx() which was very unpredictable/inconsistent (too much jitter) allowing FPS to wander and take a long time to reach steady state.

Update:  Just rechecked the code.  Nano-sleep is only used during Freeze Frame and Offline modes, not live camera modes.

-DNO_DRAG=1 added as an option to replace drag scrolling with jump scrolling for "CPU challenged" hardware.

FWIW, I had installed Pi Desktop into a VirtualBox guest to test with the PiOS without the actual hardware. 

I passed the Topdon TC001 through to the guest.  I could never get the camera to work in the proper pixel format.

The issue is that the VM is passing the camera through as Motion JPEG instead of its native 'YUYV' (YUYV 4:2:2) pixel format.  Motion JPEG is a lossy format, thus is useless to mine the thermal data.

Replacing drag scrolling with jump scrolling provides a better user experience on "CPU challenged hardware" while the camera is online  but isn't necessary in freeze frame or offline: The benefit of it is that it prevents the live image stuttering.

Seeing some improvement in fps from the single thread version, and the "CPU challenged" single core RPi zero and RPi1 need all the help they can get

Yep, will add -DNO_DRAG=1 to optionally disable drag scrolling, but even without it, it doesn't stop the user from using the click jump-scroll method.

This is true and a fair point, I was more thinking of a users first impression of the user experience because it causes the live image to stutter.

FAST_DRAG may speed up that stuttery update behavior.

Felt slightly less smooth at any given frame rate than I'd expect.

Part of what you are experiencing is 25 FPS.

Question, did it feel smoother in older versions ? 

I haven't noted any reduction in performance compared to older versions no. I was drawing a comparison to other Pi models with better CPUs, they felt smoother while reporting similar fps, eg RPi zero offline 1x double dragging rulers at ~22fps vs doing the same on RPi 2/3 at a higher scale with the same or even slightly lower fps. I wonder if this is due to them having 4 CPU cores instead of 1.

[G28]

The FAST_DRAG mods only apply to ruler plots.  The improvements in the single thread rendering of single temps warrant refactoring the other parts of the code for the single threaded hardware.

I can make a conditionally compiled hybrid jump/drag scroll version, but don't know if it will confuse users why drag works in one mode and not the other.  Guess that is what documentation is for. 

The startup stats are in milliseconds.  Getting to PKB is taking less than [10-20] milliseconds, so I have to attribute the majority of the 11-12 seconds to loading off the SD card and the app initializing global variables (e.g. additional colormaps) before calling main().  I can add a flush to stdout after the prints to see if they appear sooner, but I don't think I can do anything about the SD load speeds.  Maybe the Pi needs a ramdisk to load apps from.

Finally got a bit of time to play with it on an ODroid.  Some notes, and I'll provide longish dumps so others can see the expected output...

You need both the OpenCV dev tools and the V4L utilities to run it, and for the build CFLAGS using -march=native would be a lot easier than having to set device-specific options, so "CFLAGS='-march=native -pipe -fomit-frame-pointer'" is a one-size-fits-all entry:

Code: [Select]

# This will install ~500MB of gunk
sudo apt-get install libopencv-dev
./build_redux
sudo apt-get install v4l-utils

When you plug in the camera it'll turn up as a generic USB camera:

Code: [Select]

Now I'm stuck in a maze of X11 plumbing to try and get it to display output via SSH-forwarded X11... would it be possible to add a -b batch-mode flag to just grab a frame of video and dump it to disk?

Another bit of feedback, it's annoyingly chatty which means I keep having to scroll back through all the output to find the bit I want, it'd be good to have the credits and usage only displayed in response to '--help' so you can see the useful output at a glance.

[Amish Technician]

for the build CFLAGS using -march=native would be a lot easier than having to set device-specific options, so "CFLAGS='-march=native -pipe -fomit-frame-pointer'" is a one-size-fits-all entry:

Agreed. I used device specific options so I could cross compile code optimised for slower RPis on a faster RPi, however for the purposes of sharing on github I think your suggestion makes a lot more sense as most people will compile on the device it will run on.

Good idea, how about verbose mode option '-v  --verbose'

and a help option '-?  -h  --help'

[G28]

...

Thanks for the update.

My TC001's serial number is the same as yours.

Added a "-quiet" flag to quiet STDOUT prints and stat logging prints.

Added a "-help" flag to print and exit.

Will add "-snapshot prefix" and "-record prefix" 'batch' features to the TODO list.

Will investigate the camera open error.  I disabled it via the "-quiet" flag during the interim.

[G28]

Good idea, how about verbose mode option '-v  --verbose'

and a help option '-?  -h  --help'

I will move stat logging over to "-verbose" or "-stat" once we get the single threaded platform optimizations finalized.

[G28]

Requested feature:

"-snapshot [prefix]" and exit has been added to the pre-release.

If the optional prefix isn't added, it uses the default timestamp naming convention for the .png and .raw files.

[prefix] can consist of alpha-numeric characters, underscores and hyphens as long as it does NOT start with a hyphen to differentiate it from a command line -flag.

[Amish Technician]

The banding/shimmering issue isn't caused by redux, I've checked with all my RPi's opening the TC001 as a capture device in VLC:
RPi Zero   Good
RPi Zero2 Minimal
RPi2v1.1   Bad
RPi2v1.2   Minimal
RPi3v1.2   Bad
RPi4          Good
RPi5          Good

I'll look into this further to try and understand what causes it/how to mitigate it.


The test version DRAW_SINGLE_THREAD has yeild a further improvment in FPS for the single threaded RPi zero. Props G28 for the significant improvements since I first tested on the RPi zero and it struggled to get above single digit FPS. 

RPi Zero v1.3 - No Drag

Good idea, how about verbose mode option '-v  --verbose'

and a help option '-?  -h  --help'

Yup, sounds good.

Just setup my Topdon on my RPi 4 this weekend and wow this is awesome! I've been messing a round with the FLIR Lepton the last few months but have been kind of disappointed by the lack of community development and wanting a higher resolution. I made a 3D model of the Topdon and I'm gonna adapt the bootleg zoom lens I made for the Lepton. If anyone's interested I can share the design.

I've got a question about the images below. What is that gradient affect happening to the right image? I was able to enable the 8-bit AGC Histogram Equalization on the Lepton and that's what it looked like.
