People estimating apparatus, number-of-people estimating program and passing number estimating apparatus

摘要

The person number estimation device (10) detects a person passing through the detection range by a sensor (31) whose detection range is a part of the target region. The number-of-people estimating apparatus (10) uses a parameter corresponding to at least one of the shape of the passage connected to the target region and the position of the detection range of the sensor (31) in the target region, from the detected number of people, the target region And estimates the number of people who have passed outside the detection range. As a result, the number-of-people estimation device (10) calculates the number of people who have passed through the entire target area.
