Is the resolution on the O3R camera fixed?

[mehranq]

Hi. Following is the configuration of an O3R camera with its 3D wire connected to port2 on the VPU. I see the resolution is set to 172x224. I understand that this is the maximum resolution for the camera. My question is, can we change the resolution to a lower setting? Or is it fixed to the max resolution and thus unchangeable through json manipulation?

The resolution is fixed, as of right now we do not provides utilities for lowering the resolution.

Thank you for the clarification.

Hey @mehranq , you can run a docker container on the VPU and downsample the data on the VPU for your application.
