Log ERROR #114

Log file entry says delete all files in /home/pi/speed-camera/media/recent.

I'm missing cars (unfortunately, fast cars!) and wonder if this is the problem.

Also previous error: ERROR deleteOldFiles Possibly symlink destination File Does Not Exist Is there a solution that doesn't require manual intervention? Running picam on a RASP 4B.

Thought this was funny. speed-56-20220615-0752101

To clear up recent folder issues just delete all entries in the recent folder.

cd media/recent rm *

This will delete all the symlinks but as more data comes in newer ones will be created up to the specified max setting in config.py

https://github.com/pageauc/speed-camera/wiki/How-to-Tune-Motion-Tracking-Settings See this wiki. You may have to adjust the timeout and x_diff settings per link above.

As a total neophyte to other neophytes, I recommend tutorials on openCV tracking. See for example https://www.youtube.com/watch?v=MkcUgPhOlP8 Perhaps it will explain why a runner is tagged a 56.5 mph.
