A zone that can be selected and count how many objects are inside the zone. Use cases are:
- parking places, which shows if a parking place is free or occupied.
- queues, count the number of people which are in a queue.
Could be used for example to estimated the wind speed (the webcam is spotted to the windsock of an airport)
The zone could be a vector or bitmap mask. Could be used also to hide (or blur) part of a image to respect privacy.
we'll start working on this but need more practical use cases. @pyrog thanks for the wind speed measuring application.
a short-circuit to this could be line-crossing metrics, and wind sock would be dependent on angle to the wind, so might be a heavier lift.
Could be used on the roads to measure number of cars that passed between two line fo example.
- Used by government to measure road throughput in different time of the days. Optimize traffic lights times. Detect traffic jams.
- Used by publicity agencies to check which road is better to use for placing a billboard.
