  • Can I get higher FPS if I use 640x400 resolution?

I need to process videos for at least 200fps. And OAK-D can do 120 fpst at 720P. Can it be faster if we use 640x400 binned images?

    Hello frankshieh , sorry for the delay. Mono camera max framerate is 120 FPS, so 200FPS wouldn't be possible with the current mono sensor. If you are interested in higher FPS I can check internally with the team if we have any support for other sensors that have higher framerate.
    Thanks, Erik

      I have check your c API source code, you do have a 400P mode. If I change to this mode, the data is reduced to 400/720. Theoretically the FPS can be increased from 120x720/400=216 FPS. The INTEL D435 has their new firmware that reduce the lines to 100 lines and can get 300fps for faster applications.

      At the moment, the OV9282 sensor configs we use have limits as:

      • 1280x800 and 1280x720: 60fps
      • 640x400 (binning enabled): 120fps

      We will need to replace the register configs in firmware, to be able to achieve higher FPS. Advertised from Omnivision:

      But maybe higher is possible lowering the bit depth (from the current 10-bit to 8-bit), and we should also add custom sensor resolution config, to apply cropping (reducing number of lines, thus allowing for an even higher FPS).
