VOXL M500 vision problem!!
-
Is the tracking camera looking at interesting "features" when it takes off, or is it just white floor? If it can start on a carpet or something, the vision system will have something to track. this will help VIO reduce drift.
-
it just is a whitle floor like this
-
Can you put some pieces of duct tape on the floor or something to make it more interesting to the VIO system? Especially since it looks like that floor might be reflective. Random small pieces of tape, like electrical or duct tape, would likely help.
You can monitor the VIO stability on QGC. Those numbers should stabilize after takeoff, but obviously you want them stable on the ground too.

hi, here is the video i just captured https://drive.google.com/file/d/1Am63zD09am8nx_BBpAB2JfTYcf_IFMST/view?usp=sharing

the local NED position is look good at the init state as well as when i move the drone into the other location.
-
thanks for sending, I will pass along to someone more familiar. Was this all working before? Do you know what has changed?
-
last week it used to work normally. i did't changed any strange thing, just re-configuration the drone to the factory state. by "voxl-configure-vision-px4 -f" to take again the NED position cuz before that i had config vision lib by "voxl-configure-modalai-vl" and the local poistion is lost.
-
pls help me soon. we can set up an online support via teamview to make the problem more clearly.
-
Does this behavior only occur in PX4 position mode? Does it fly in PX4 manual mode?

@James-Strawson yes,we only test uav in position mode. we didn't use manual for testing.

There's a few files (as we use DRY even on params
The procedure to do this is hereWhen you reload the airframe (via these parameters) you'll end up losing calibration and having to go through the calibration process. This is documented here
You'll end up loading these, in this order:
-
configures core airframe for m500 with 4S battery (standard):

VIO indoor EKF

Serial params (to be safe, these should be set by default)

If needed and applicable, radio
