When I set COM_OBS_AVOID to 1, the drone will immediately go into Not Ready mode. After doing some looking, I think it's because GPS shows as ERROR. I am not quite sure why the GPS has an error, but it's been like this for a couple of days, even before I tried to setup obstacle avoidance. The logs show a 'No known GPS device found' error which could be substantial:

The GPS model is MATEKSYS M8Q-5883 GPS Module, and the light on it is solid red. Apparently a flashing blue light means it is 3D fixed, but I'm not sure if that means anything.

I am not sure if this is a hardware issue or if there is something specific I need to do to setup the GPS so that it is not in error state. When I bring the drone outside, it does show that it gets GPS connection, even though GPS is in error state.

Any suggestions?

We managed to fix the intrinsic file not generating by deleting the already existing extrinsic file

We managed to get it to work once after changing the lighting in the room, but we cannot get the intrinsics file to generate for some reason

Hello again.

So I've been trying to calibrate the cameras on a VOXL Flightcore and everytime the calibration is finished, a max reprojection error happens. I am not sure what this is caused by.

Is it due to the camera quality? It's strange because it has happening on both of the drones I'm working with.

@Chad-Sweet Yeah connecting it to ethernet fixed it. Also the video helped a lot. Thank you very much!

We connected it to ethernet and it's a bit faster, but still very laggy. Any suggestions?

When I'm trying to set it up, it isn't tracking the squares the entire time and just flashes occasionally and the video feed is super laggy. Is there a way to fix that? Perhaps it's a lighting issue? Maybe the lag is because it's connected to the internet wirelessly?

Is the camera calibration supposed to be super finicky? I've been holding up a checkerboard for an hour and it's been pretty difficult getting the camera to detect it. The hardest part I've been stuck at is when the checkerboard needs to be tilted away from the camera. Any suggestions? It's super difficult getting the camera to detect it.
