Title:
MOVING OBJECT DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/148423
Kind Code:
A1
Abstract:
Provided are a moving object detection method and apparatus. The moving object detection method comprises: receiving an optical signal from a scene to be subjected to detection, and performing optical imaging on said scene by using the optical signal, so as to generate imaging optical signals of said scene, wherein said scene comprises an object to be detected that is moving; within a predetermined time period, sequentially modulating the imaging optical signals by using modulation signals in a modulation signal set, so as to generate modulated optical signals, and generating an encoded image on the basis of the modulated optical signals; and performing detection on the encoded image by using a moving object detection algorithm that matches the modulation signal set, so as to identify said object in the encoded image. In the moving object detection method provided in the present disclosure, the category of a moving object to be detected and a plurality of groups of position information in chronological order are recognized from a single encoded image, without the need of a high-speed camera, such that the efficient tracking detection of a high-speed moving object can be realized.
