Passenger counting device, system, method and program, and vehicle movement amount calculation device, method and program
First Claim
1. A passenger counting device comprising:
- a movement amount calculation unit, implemented by a processor, for calculating a movement amount of a vehicle based on an image of the vehicle;
a depth distance calculation unit, implemented by the processor, for calculating a distance in a depth direction of a face of a passenger of the vehicle based on the movement amount of the vehicle; and
a passenger number determination unit, implemented by the processor, for detecting the face of the passenger of the vehicle from the image and determining a number of passengers of the vehicle based on distances in the depth direction of a plurality of detected faces of passengers.
