Hi I am looking at doing analytics such as line crossing and occupancy dwell etc as a post processing using the broker to a rabbitmq. I have managed to create the first post processing module to determine if a tracking id has cross a predefined line but I have now run into a scaling issue in that the detections are sent to the broker in the source resolution and my line draw is fixed at 1920x1080. I need to add a scaling factor to the detections so am looking at how I get the source resolution and attach to meta for the broker to send
