Using the sample frame grabber program provided with Driveworks on the Orin 6.0.6 platform, when running with 6 IMX728 cameras with ISP enabled with, I observed significant frame dropping.
I set the cameras to run at 30fps, 3840x2160 resolution, camera:V1SIM728S2RU4120HB20, and observed that ~60% of the captured frames were dropped @ ISP time.
I would like to to understand:
- Is the Orin platform expected to be able to run these 6 cameras at this framerate + resolution without dropping frames? Is there some inefficiency in the sample code or is this a fundamental HW limitation?
- Is there a way to reduce the frame rate for this camera down to 10Hz as a part of the sample driver code, or the driveworks api
I know the max ISP throughput of the Orin-X is 1.85 gigapixels per second, which should handle 30fps, 3840x2160 x6 cameras by that metric. Is there some inefficiency with the sample Driveworks camera application, or some other issue?
Statistics results for 6 cameras, 30fps, 8MPx:
