Publication number: 20230410323Abstract: An environment is captured with a set of sensors to generate a thermal image from an infrared sensor and a visual image from a visual light camera. The thermal image is used to predict movement of objects detected in the environment. The thermal image may be combined with the visual image as a channel of data with the visual image as an input to a prediction model that predicts object movement. Alternatively, the visual image may be used as a guide to identify relevant portions of the thermal image. Objects may be detected and segmented in the visual image and the corresponding portions of the thermal image are segmented and used to predict thermal characteristics for the object. The thermal characteristics may then be used for object movement prediction.Type: ApplicationFiled: June 17, 2022Publication date: December 21, 2023Applicant: GM Cruise Holdings LLCInventor: Siyuan Lu
