2results about How to "Achieve accurate positioning" patented technology

The application belongs to the field of track assembly and relates to a positioning mechanism for assembly, which is used for positioning a plurality of products arranged in a straight line. The positioning mechanism comprises a bottom base plate, a locking piece and a correcting piece. The bottom base plate has a front surface and a back surface. The back surface is configured to be connected with the ground in a positioning mode, and the front surface is configured to support the splicing ends of two adjacent products. The positioning mechanism can quickly realize accurate positioning of the products through cooperation of the locking piece and the correcting piece, so that the positioning operation can be quickly realized when the products are spliced. In addition, the splicing accuracy of the two products can be ensured through the correcting piece. Once position deviation occurs after splicing, the correcting piece can be used for re-correction, and the efficiency is high and the maintenance difficulty is low.

The embodiment of the invention provides a vehicle positioning method, electronic equipment and a vehicle. The method comprises the steps that vehicle positioning data, vehicle environment information and road-level map data are acquired; determining the initial position of the vehicle according to the vehicle positioning data; determining real-time road data according to the vehicle environment information; matching the real-time road data with the road-level map data, and determining a position correction parameter; and correcting the initial position of the vehicle based on the position correction parameter, and determining the target position of the vehicle. The method gets rid of dependence on an external base station, solves the problem that a sensing device cannot obtain effective lane information, reduces the dependence on map precision, and can achieve the accurate positioning of a vehicle at high efficiency and low cost.
