                  The image is showing some disparity data there, the image is often very dark because it will be black if the dfs algo is unable to match regions and we do a lot of filtering to get rid of noise, but you can see 2 blobs there that it recognizes. If you're shoing the stereo cameras a blank wall or a repeating pattern it will be unable to properly match data.

                    @Alex-Gardner That's good to know! How can I get the Obstacle Detection message to be sent to the QGC?

                      the file at /etc/modalai/voxl-vision-px4.conf has settings for QGC IP, enabling VOA, and sending VOA to QGC. Make sure that the latter two are enabled and that your qgc ip is correct and it should send to QGC
