seatedPeople count #4

Hi,

According to your experience is it possible to count seated people in bus with mmradar technology cost effective way ?

any advise for direction ?

In my opinion, the visible-light camera is a better choice for the scenario you mentioned. Because the MmWave radar has strength in some inclement weather, but the conventional camera is more suitable for bus monitoring. And I believe there already exists some mature solutions with computer vision algorithms for people counting in various scenarios. By the way, I also think it's easier to detect moving targets with mmwave radar considering that the signals from fixed background and static objects are hard to distinguish.

Hi,

Privacy is the problem in visible camera . Due to regulations its not possible to use normal camera which is face visible that could be recognized.

What I assume that : Take the mmradar signals when the bus empty.. and after start moving take another signals to compare.

I don’t know is there any camera that doesn’t show face and body details only for counting.

Best

Hi~ yes, as you mentioned, perhaps privacy is a problem for conventional visible cameras. Cameras that don't capture faces include infrared cameras, event cameras, or just low-resolution visible cameras, etc. But event cameras may not so commercially available, and they are only sensitive to moving targets. Emmmm, but I'm curious about the reason why you don't use the ticket record for people counting in buses.
