Hi, I am thinking of the best way to measure the available space (in percentage) in an elevator with a camera mounted on the ceiling. There can be persons or objects (like trolleys, carts, etc.) inside.
A possible very simple idea (we don’t take image distortion due to top view into account):
- detect the floor area when the elevator is empty (kind of initialization) and draw a rectangle on it
- draw bounding boxes on foreground elements (people, objects, etc.)
- do intersection of all the foreground bounding boxes with the floor area (to get the occupied space)
We don’t need classification, as what matters is the foreground objects (whatever they are).
Does OpenMV have any multiple bounding box model ?
