I have a room (a waiting room) about 10x10 meters and I would like to locate people in there. The ceiling in the room is really high, so I can place a radar above in any height I want. My questions:
Is it possible to use some ready/made radar/lidar solution to detect what seats in the room are currently used by people?
Is it possible to detect people moving in the room on the fly (~30fps)?
Is it safe to use radar on humans?
I know there are papers on this topic. However, I am not sure if there is any reasonable inexpensive solution for ordinary people. Something I can plug in PC and read raw data to process in any software I develop.
There will be cameras. This measurement should be a complement to the camera machine vision to make it more reliable. I have experience with development of machine vision systems in difficult environments (mainly industry environment) and they have never worked as intended.
I also thought about tensometers, accelerometers, or microphones in the chairs to just locate sitting persons, but I would like to avoid collecting 20-60 channels.
