Calibration method, device and equipment for roadside radar and storage medium

Abstract

The invention discloses a calibration method, device and equipment for roadside radar and a storage medium. The method comprises the steps: acquiring position data, measured by a positioning device ofa reference vehicle, of the reference vehicle; wherein the position data comprises position information of a plurality of time points; acquiring radar data of the reference vehicle measured by a to-be-calibrated road end radar; wherein the radar data comprises radar information of a plurality of time points; determining calibration parameters of the to-be-calibrated roadside radar according to apreset radar observation equation, the position data of the reference vehicle and the measured radar data of the reference vehicle; wherein the radar observation equation is constructed based on the relationship among the radar information of a target object, the position information of the target object and the calibration parameters of the to-be-calibrated road-end radar; and calibrating the to-be-calibrated road end radar according to the calibration parameters of the to-be-calibrated road end radar. By adopting the embodiment of the invention, the calibration of the road-end radar can be efficiently and accurately realized.

Description

technical field [0001] The present invention relates to the technical field of radar, in particular to a calibration method, device, equipment and storage medium for roadside radar. Background technique [0002] With the development of information technology, more and more radars are installed on the roadside to enhance the perception of vehicles. In order to ensure the measurement accuracy of the roadside radar, it is necessary to calibrate the roadside radar. At present, it is generally to manually place a number of corner reflectors at the specified position on the road surface, and then use several corner reflectors with known positions to perform roadside radar calibration. calibration. However, the inventors found in the process of implementing the present invention that the calibration process of the existing roadside radar is inefficient due to the need to manually place several corner reflectors, and once the position of the corner reflectors used for calibration d...
