<![CDATA[OV9782 VIO jumps but does not reset]]>Hi there!

We are using the OV9782 with a VOXL2 on sdk1.0 to pass VIO along to an external autopilot. The system is performing well, but when I inspect the logs on the autopilot side I see that the estimate tends to jump sometimes. The qvio pipe does not return resets, lack of features or error codes. The logs on the autopilot sider show this:
52859acd-8f17-4e65-9019-1f616891c1c5-image.png

Those small jumps are causing a lane switch in the EKF. From time to time it will cause it to throw a failsafe.

Similar flights with the OV7251 camera do not show the same problem. Although we do get hard resets in that case.

Is the higher resolution camera making the system drop frames or messing with the timing? Should the parameters in the qvio-server change for this camera? Any help/pointers/ideas would be much appreciated.

Cheers!

Do you have an easy way to trigger a capture when certain conditions are met? It is hard to correlate hundred of images to the autopilot logs to find these instances. We are working on streaming the qvio-overlay as an RTSP stream down to the GCS. That might be easier.

Unrelated question. Can the VIO algorithm use the colored images coming from the camera? If yes, is there an advantage at all?

voxl-logger --preset_odometry might be useful as well
