Fixed YOLO Model Problem:

06-16-2024

Realizing that VLC was the most likely cause of our frozen frames when running camera streams, since we verified that our YOLO models were the same and that a pipeline was successfully being created, we looked around for another media player that had the ability to capture a camera stream from an IP camera. Siddarth found mpv, and when trying to access the stream through mpv, we were able to see bounding boxes around the Buoy in real time, along with the actual correct label.

Fig. 1: Accessing Graey camera stream through MPV as an alternative to VLC. See that after typing “mpv” into terminal on Ubuntu, the only thing necessary to access the stream is to type “mpv –fs <IP Address TO ACCESS STREAM>”.

Fig. 2: Camera stream accessed through MPV when running Buoy model through OAK-D on Graey. Note that the label “Buoy” is present. Additionally, we will have to do something about the red tape on the outskirts of the visible frame on Graey, as that is messing with the YOLO detection.
