Abstract

The invention relates to a generation system for a high-precision road map and belongs to the technical field of high-precision maps. The purpose is to solve the problems that the workload of producing or updating an existing high-precision map is large, and cost is high. High-precision positioning and high-precision matching are achieved relative to the existing map, existing information of the existing map is fully utilized, and the workload and cost for producing / updating of the high-precision map are lowered. The generation system is characterized in that road elements recognized through deep learning, computer vision and other methods and obtained accurate relative position information form a ground one-dimension thick and space three-dimensional sparse map similar to Mobileye, and the map can be matched and fused with an existing traffic information system GIS-T. Based on an existing low-precision electronic map, a positioning system and a vehicle-mounted camera, producing / updating of the high-precision map are achieved at a low cost. The generation system is used for producing or updating the existing high-precision road map.

Description

technical field [0001] The invention relates to a generating system of a high-precision road map, and belongs to the technical field of high-precision maps. Background technique [0002] Traditional maps only store a small amount of label information for road features such as road centerlines and road names. These information can only represent the greatly simplified actual traffic environment, and cannot reflect the detailed conditions of the road with high precision. Compared with traditional maps, high-precision maps can provide high-precision coordinates, detailed road information such as accurate road shapes, lane lines, traffic signs, slopes, elevations, and rolls, as well as rich geographical elements, which can provide accurate information for the future. The latest technologies such as location based services (Location Based Services, LBS) and unmanned driving provide a solid foundation, so they have received more and more attention. Especially when severe weather...
