Map Data Processing and Format Change Method for Land Vehicle Simulation

摘要

The present invention is based on information on lanes (regulatory lines, road boundary lines, stop lines, lane center lines) necessary for autonomous driving, road facilities (median strips, tunnels, bridges, underpasses), and sign facilities (traffic safety signs, road surface markings, signal flags) This method relates to a method of processing map data and changing the format with precision for simulating land moving vehicles. a step 11 of composing spatial data providing a location and attribute data defining an attribute of an object; a step 22 of having a structure referring to the LINK defined by the centerline of each lane configured in step 11, defining and classifying the LINK as dominant data and the rest as dependent data; Each lane center line classified in step 22 is given a unique identification number LINK_ID (region code + serial number + direction identifier + lane), and using this, the lane center line constituting the unit road is identified and grouped, and the line ( Lane center line) is grouped to internally configure a road shape composed of a two-dimensional plane, and using the road shape composed of the two-dimensional plane is used for autonomous driving by recognizing it as a road that can be driven in a land vehicle simulation. characterized.
