Document Type and Number:
WIPO Patent Application WO/2021/079866
Kind Code:
A1
Abstract:
A station platform safety support system in which a first bird's-eye view camera and a second bird's-eye view camera are installed at different locations to photograph the same monitoring section in a linear shadow caused in a gap between a train and a platform. A processing device (200) is provided with: a first no-correspondence portion detection unit (241) for detecting, in a first photographed image by the first bird's eye view camera, a first image no-correspondence portion in which the image of the monitoring section does not correspond to the linear shadow; a second no-correspondence portion detection unit (243) for detecting, in a second photographed image by the second bird's eye view camera, a second image no-correspondence portion in which the image of the monitoring section does not correspond to the linear shadow; and an existence determination unit (245) for determining whether or not an obstructive object exists, on the basis of the difference between the first image no-correspondence portion and the second image no-correspondence portion.
