The invention relates to the technical field of vehicle automatic driving, in particular to an automatic driving positioning method and device, an electronic device, a storage medium and a vehicle. The method comprises the following steps: receiving first position information sent by a road side unit; acquiring second position information of the road side unit relative to the laser radar through the laser radar on the to-be-positioned vehicle; determining the relative distance between the laser radar and the road side unit according to the second position information; determining coordinates of the laser radar according to the relative distance and the first position information; and correcting the radar coordinates according to the coordinate correction conditions to obtain positioning coordinates of the to-be-positioned vehicle. The problem that an automatic driving vehicle cannot be positioned through a GPS system when encountering an obstruction is solved, accurate positioning of the automatic driving vehicle is achieved through the roadside unit, the vehicle-mounted laser radar and a simple and accurate calculation process, the required cost is reduced, and a calculation platform with very high calculation force is not needed.
Description
technical field [0001] The invention relates to the technical field of automobile automatic driving, in particular to an automatic driving positioning method, device, electronic equipment, storage medium and automobile. Background technique [0002] The current common method for real-time positioning of vehicles by automatic driving systems is to read the real-time data of the GPS (Global Positioning System) integrated navigation system. On the ground, the GPS integrated navigation system can collect satellite signals in real time. At this time, the positioning data is accurate and In real time, when the vehicle travels to the underground parking garage for a period of time or stays in the underground parking garage for a long time, the GPS navigation system calculates the position information through the internal inertial measurement unit. It is more convenient for ground and open areas, but when encountering occlusion or complete occlusion such as underground parking garag...
