The invention discloses a vehicle
laser radar and camera combined external parameter calibration method and
system, and the method comprises the steps: obtaining
laser point cloud information, video information,
radar point cloud information, differential positioning information, navigation information and vehicle attitude information in the driving process of a target vehicle; the information is subjected to
time synchronization and information alignment of a
signal level based on a gPTP protocol,
information type fusion, attribute fusion, topology fusion and
logical reasoning are carried out, target parameter information is obtained, finally, the target parameter information serves as a true value control group to be compared with initial external parameter calibration parameters of a target vehicle, and the target parameter information is obtained. Invalid values in the initial external parameter calibration parameters are screened out, and the combined external parameter calibration parameters are obtained. According to the method, the combined external parameter calibration of the vehicle
laser radar and the camera can be realized in the driving process, and when the position of the intelligent driving sensor on the target vehicle deviates, deviation compensation can be carried out through non-inductive real-time external parameter calibration, so that the vehicle use experience of a user is improved.
