Publication number: 20180150704Abstract: Provided is a method of detecting pedestrians and vehicles based on a convolutional neural network by using a stereo camera, for generating a disparity video through stereo matching in a video photographed by the stereo camera, detecting object candidates by using the disparity image, and detecting the pedestrians and the vehicles through an object detection process for the detected candidate. The method includes receiving a stereo video; acquiring a disparity video from the stereo video using stereo matching to convert the disparity video into a depth video; extracting object candidates by analyzing a histogram of the depth video; and detecting an object by using a convolutional neural network to be detected among the object candidates. Object candidates are detected using disparity video in advance, and one of the object candidates is detected whether it is a pedestrian or a vehicle, such that less time is required.Type: ApplicationFiled: November 28, 2017Publication date: May 31, 2018Inventors: Gyu-Cheol LEE, Jisang YOO
