I am working with OpenMV Cam h7 plus and MT9V034 to detect April Tags.
I have tried the built-in examples of OpenMV IDE (find_apriltags.py), the fps remains good till the moment I am not doing any processing and simply grabbing and displaying frames. When the code does processing in terms of calling the April Tag library functions and collecting the (x, y, and theta), the fps drops down to ~30 fps. This happens even in the case of QQQVGA mode. Is there any fix for it?
Also, taking the data from the sensor and publishing it in ROS was also performed. The fps was still low i.e. ~43fps (in QQQVGA mode). There was no other operation performed(not even printing of published data) during this process and then also the fps was less.
Could anyone please suggest any help on this?
