I'm working on a project which involves saving a stream of images to an SD card as jpeg on the OpenMV H7. The camera is expected to take hours of footage at a time, and the hope is that it would be at a high enough frame rate for a machine vision algorithm to be able to look at offline. The goal for now is to try to achieve a consistent 5 fps.
However, what I've noticed is that simply using in a loop (sensor taking image resolution QVGA)
Code: Select all
img = sensor.snapshot() img.save(filename)
