I’m playing with the Global Shutter Camera Module + OpenMV Cam H7. I’d like to have a higher fps, more than 200 fps, with maintaining the spatial resolution. I tried the example code in github: openmv/scripts/examples/28-Global-Shutter/high_fps.py with sensor.VGA, sensor.QVGA, and sensor.QQVGA options. I was able to get a high fps with QQQVGA but the spatial resolution is degraded. The fields of view are the same between VGA and QQVGA. So, I guess that the QQVGA mode is realized by pixel binning. However, I’d like to avoid the pixel binning, since this results in the spatial resolution reduction. I’d prefer to do windowing or setting ROI. So, I tested the windowing by using the function sensor.set_windowing() with VGA framesize. However, the frame rate is low, the same fps as the VGA without windowing.
Is there a way to achieve higher fps with original spatial resolution? Any suggestions?
