I want to trace vehicles using Python path as shown in the video https://www.youtube.com/watch?v=BP1OMyYuyy4 I have detected bounding box and have centroid location for every car for each frame. Currently you can see my work on this video https://youtu.be/f8-Z1pfugC4 I just don't understand how to keep the plot of path while video frames are in loop ?
I found the answer and the answer lies in the usage of deque module as demonstrated in "Ball Tracking by Adrian" tutorial.

Check this website ,this module may help for path tracing
https://docs.python.org/3/library/trace.html
You should save a trajectory for every car and drawing it every frame, for example as polylines (for a single object). Example in the attachment.
