Passenger counting apparatus using computer vision and passenger monitoring system thereof

摘要

The present invention relates to a computer vision technology that recognizes and analyzes an image in a vehicle, and the passenger counting device distinguishes between an input unit receiving an image of a passenger getting on or off the vehicle and a passenger getting on or off from the input image. It includes a processing unit that counts passengers in the vehicle based on the direction in which the passenger moves when getting on and off by identifying, and the processing unit separates the left image and the right image based on the vertical center line of the face area detected in the input image, and then The image distance value is calculated by acquiring the left and right image feature matrices in consideration of the difference component based on each image on the right, and face recognition is performed through a classifier by combining the calculated distance values of the left and right images, A feature point is detected from the recognized face region, and a limited regional sparsity encoding is performed on the detected feature point to recognize a facial posture that is distinct from the background in the image.
