Patent number: 9727780Abstract: A pedestrian detecting system includes a depth capturing unit, an image capturing unit and a composite processing unit. The depth capturing unit is configured to detect and obtain spatial information of a target object. The image capturing unit is configured to capture an image of the target object and recognize the image, thereby obtaining image feature information of the target object. The composite processing unit is electrically connected to the depth capturing unit and the image capturing unit, wherein the composite processing unit is configured to receive the spatial information and the image feature information and to perform a scoring scheme to detect and determine if the target object is a pedestrian. The scoring scheme performs weighted scoring on a spatial confidence and an appearance confidence to obtain a composite scoring value to determine if the target object is the pedestrian.Type: GrantFiled: December 30, 2014Date of Patent: August 8, 2017Assignee: Automotive Research & Testing CenterInventors: Kuo-Ching Chang, Yu-Sheng Liao, Pang-Ting Huang, Yi-Ming Chan, Li-Chen Fu, Pei-Yung Hsiao
