DEVICE, METHOD AND PROGRAM FOR MEASURING NUMBER OF PASSENGERS

摘要

Although persons on board in a driver's seat and a passenger seat can be detected, it is difficult to detect persons on board in a back seat and thus the number of passengers cannot be accurately measured. Image obtaining means 100 photographs the inside of a vehicle from the outside of the vehicle (a shoulder, etc.). View determining means 102 estimates the way in which the vehicle in the image photographed by the image obtaining means 100 is viewed, and outputs a view determination result. Person detecting means 101 performs front-face, side-face, and angled-face detection on the image photographed by the image obtaining means 100, to detect persons and outputs a person detection result. In-vehicle position estimating means 103 determines at which positions in the vehicle the detected persons are present, using the person detection information and the view determination result information, and outputs in-vehicle position estimation information. Result integrating means 104 integrates detection results obtained for a plurality of images which are photographed consecutively, to calculate the number of passengers.

主权项

1. A device for measuring a number of passengers, comprising:
an image obtaining unit for obtaining an image; a person detecting unit for detecting persons on board a vehicle from the obtained image and generating a person detection result, the vehicle being a target for measuring a number of persons; a view determining unit for determining view indicating how the vehicle is viewed in the image, and generating a view determination result; an in-vehicle position estimating unit for estimating, from the person detection result and the view determination result, at which positions in the vehicle the persons are on board and generating, for each image, an in-vehicle position estimation result; and a result integrating unit for integrating the plurality of in-vehicle position estimation results obtained for the vehicle and determining a number of passengers from an integration result.
