Simple People Counter Using Radar

Radar uses simple detection filtering to count people, vehicles, or other objects.

Hey,

Got a quick question:

@ops_radar

Of course it does not have to count just people but could count robots, vehicles, or pets. Additional filtering on signal magnitude allows the sensor to further refine what it counts and what it does not count.

If one of those sensors (bonus sub-question: which one would be most appropriate, if any?) was attached to a moving object and mounted perpendicular to the direction of motion could it be used to count objects that pass its “detection region”, even though the objects would be coming in/going out from the sides?

Also, if yes, what would be the limitations such as relative speed of the objects detected to the moving object the sensor is attached to?

Sincerely,

edit: Added this for clarity:

The fact that the sensor is moving complicates things. If the objects are in the general range of detection, you should get a count provided the speed is not too fast.

Thanks for the answer!

@ops_radar

you should get a count provided the speed is not too fast.

What would be considered “not too fast”? I’m assuming there’s not hard data here, but I’m thinking a few km/h (walking to jogging speed). Do you think that would work?

Sincerely,
