'corrupted size vs. prev_size' error message #39

Open qiyan98 opened 3 years ago

qiyan98 commented 3 years ago

Hi, thanks for your contribution on this apriltag package. But from time to time, I see the corrupted size vs. prev_size error message in the program. It is related to detector.detect(). Is there any suggestions on how to fix it?

Can confirm. I have the same issue after about 5 runs on my RaspberryPi 4B.

corrupted size vs. prev_size
aaronleetw commented 1 year ago

I fixed it by switching to the apriltag package on pip: https://pypi.org/project/apriltag/. It is based on (but not endorsed by) the AprilTags fork from SwatRobotics: https://github.com/swatbotics/apriltag.
