Problem with find_rect at higher res

OpenMV Boards

I have been able to get the find_rect example to work at the QVGA resolution but it does not wrk at higher res. I want to use SXGA. I have the RT1062 device. Is there some trick ?

Hi, no, the algorithm for that is the quad detector from apriltags. It really can’t run at a very high res.

Also, for various reasons, I plan to remove that algorithm when we upgrade to AprilTags 3 in the future.

OK. Does find line segments work at higher res ? I could use that to find intersections and then the rectangle vertices.

Yes, but, it will be slow.
