Re: Correct build and install for OpenCV and Pi4

The OpenCV install and recompile has failed. There were errors. So far no sucess in building a proper OpenCV for Pi4 with a fresh OS installed. Never thought this part would be hard.

Ever be an Industrial rated PI?

I think the community and the device is incredible but I work in heavy industry and they need industrial rated components, which means works in Operating temperature from -40C to +85C. So instantly the PI is out. I love and applaud the PI 4 because it checks a LOT of makers boxes but without the ind...

So what do you use to speed up image filtering, like a haarcascade. I agree opencv is not optimized.

Re: Pi Camera vs USB WebCam for OpenCV

What I don't know is if decompression of the video frame or transfer from the GPU memory to CPU memory takes longer than reading in an uncompressed RGB frame to be manipulated.

So has anyone of the smart people have any idea on how to get the version that's running on Unbuntu to work on the Pi? It would be awesome. Not sure why they just dont have a piece of black box code that people could use for free use of that solves this issue.
