rmod (ver2) help please

Jason, I saw that the opencv gaussian blur function makes my framerate go down very strong, do you know if that is opencv-related?
I have a very fast computer, but as soon as I use gaussian blur I only have a fps of 1-2 frames / second left.

Guassian blur is indeed very slow, and you really only want to do it during vision processing, not for every frame from the camera.

But it makes detection better, it eliminates small reflections from the plastic tape.
I will see if I can change the algorithm in only using it on a single frame.

I tried that filter out on a clear tape which i made black with a marker. That makes detection much easier, but the light reflects heavy as it is a high-gloss plastic. Blurring this makes it better, but is very slow.
Now I look for a way to make these clear tapes black with a dull finish, that would be perfect.
I could not sonsistently place parts from clear tapes, and almost all larger Cs and LEDs come in clear tape.

The measurement algorithm in standard software does that (takes single frame for processing and measurement), not sure what r-mod does. I'll see about adding blur.

I am using 3D printed strip feeders from either blue or green material; so I can always detect the sprocket holes no matter the colour of the tape.

I have shared the design and STLs here:

Regarding reflections on tape I believe these are mostly caused by inadequate lighting; so add some more blurring to your light source and / or adjust brightness (with high speed PWM).

In addition to that, I think that sprocket hole detection is nice but in many cases it would be more reliable if LitePlacer also supported a much simpler approach:

I wish I could teach the software the center of first and last component using camera and jogging controls. By setting tape width and component pitch / component count, it could then easily do the maths and figure out the location of each part...

I documented that feature request in November last year:
