Title:
VEHICLE-ROAD COORDINATION COMMUNICATION METHOD, DATA PROCESSING METHOD, DETECTION SYSTEM AND FUSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/266863
Kind Code:
A1
Abstract:
A vehicle-road coordination communication method, a data processing method, a detection system and a fusion apparatus, which may be used in the fields of automatic driving, intelligent driving, assisted driving or the like. The vehicle-road coordination communication method comprises: acquiring data from a detection system and sending the data to a fusion apparatus, the data comprising one or more of a state process calibration value, a motion model, state information, a covariance estimation value and a time stamp, wherein the state process calibration value is used for the fusion apparatus to optimize the covariance estimation value; the motion model is used to identify the motion state of a target; the state information is used to identify motion features of the target; the covariance estimation value is used to identify errors between the state information and actual state information; and the time stamp is used to identify the moment when the detection system sends the data. By means of the state process calibration value, the covariance estimation value may be optimized, so that measurement errors of the detection system may be characterized more accurately, which thus helps to improve the accuracy of first fusion data.
