Abstract:
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.
