Person counting device, person counting system, and person counting method
First Claim
1. A person counting device that counts the number of persons passing through a doorway based on an imaged image in which the surroundings of the doorway for entering or leaving a predetermined place in a store or the like are imaged, the device comprising:
- a processor; and
a memory that stores an instruction,the device further comprising, as a configuration when the processor executes the instruction stored in the memory;
a moving line acquirer that acquires a moving line for each person detected from the imaged image;
a person counter that counts the persons that have passed through the doorway based on the moving line acquired by the moving line acquirer; and
an output information generator that generates output information which represents the number of persons that have passed through the doorway based on the counting result of the person counter,wherein the person counter includes;
a moving line interruption detector that detects an interruption of the moving line in the vicinity of the doorway;
a similarity determinator that determines a similarity between the background image in which the doorway is represented and the person image in which the person is represented in the imaged image; and
a deemed counter that deems that the person has passed through the doorway and includes the person in the counting target, in a case where the interruption of the moving line in the vicinity of the doorway is detected by the moving line interruption detector and the similarity determinator determines that the background image and the person image are similar.

Abstract
A person counting device according to embodiments of the present invention counts the number of persons passing through a doorway based on an imaged image in which the surroundings of the doorway are imaged. The person counting device includes a moving line acquirer that acquires a moving line for each person detected from the imaged image, a person counter that counts the persons that have passed through the doorway based on the moving line, and a display information generator that generates display information which represents the number of persons that have passed through the doorway based on the counting results of the person counter. The person counter detects an interruption of the moving line in the vicinity of the doorway, determines a similarity between the background image of the doorway and the person image, and includes a deemed counter that deems that the person has passed through the doorway.

8. A person counting system that counts the number of persons that have passed through a doorway based on an imaged image in which the surroundings of the doorway for entering or leaving a predetermined place in a store or the like are imaged, the system comprising:
-
a camera that images surroundings of the doorway; and a plurality of information processing devices, wherein any one of the plurality of information processing devices includes a processor and a memory that stores an instruction, and the information processing device further includes, as a configuration when the processor executes the instruction stored in the memory; a person tracker that detects a person from the image imaged by the camera and acquires position information; a moving line acquirer that acquires a moving line for each person based on the position information acquired by the person tracker; a person counter that counts the persons passed though the doorway based on the moving line acquired by the moving line acquirer; and an output information generator that generates output information which represents the number of persons that have passed through the doorway based on the counting results of the person counter, and wherein the person counter includes; a moving line interruption detector that detects an interruption of the moving line in the vicinity of the doorway; a similarity determinator that determines a similarity between the background image in which the doorway is represented and the person image in which the person is represented in the imaged image; and a deemed counter in which the person is deemed to have passed through the doorway and the person is included as the counting target, in a case where the interruption of the moving line in the vicinity of the doorway is detected by the moving line interruption detector and the similarity determinator determines that the background image and the person image are similar.

9. A person counting method that causes an information processing device to perform the processing of counting the number of persons passing through a doorway based on an imaged image in which the surroundings of a doorway for entering or leaving a predetermined place in a store or the like are imaged,
the method comprising steps of when the processor of the information processing device executes the instruction stored in the memory: -
acquiring a moving line for each person detected from the imaged image; counting the persons that have passed through the doorway based on the moving line acquired by the step of acquiring; and generating output information which represents the number of persons that have passed through the doorway based on the counting result by the step of counting, wherein the step of counting the persons includes steps of; detecting an interruption of the moving line in the vicinity of the doorway; determining a similarity between the background image in which the doorway is represented and the person image in which the person is represented in the imaged image; and deeming that the person has passed through the doorway and including the person in the counting target, in a case where the interruption of the moving line in the vicinity of the doorway is detected by the step of detecting the moving line interruption, and the background image and the person image are determined to be similar by the step of determining the similarity.
