Auto-calibration for find_blobs thresholds

Hello!

We’re using find_blobs for line follower robot to detect the line. It works fine, but it’s very sensitive for luminance intensity.

I just wonder if there are any auto-calibration alogrithms available for OpenMV cam? If you have any ideas I’ll be glad to test it.

Hi, did you see the automatic threshold algorithm under color tracking examples?

As for line following once I’ve got some much better code for a donkey car coming out soon. Just need to test it this weekend at the dyi robocar races.
