Route data conversion method, non-transitory computer readable storage medium, and route data conversion device

Abstract

The invention provides a route data conversion method, a non-transitory computer readable storage medium, and a route data conversion apparatus. The route data conversion method is used for acquiring a second route matched with a first route on a first map on a second map. The first route is represented as route nodes and route links, the route nodes being defined by latitudes, longitudes, and altitudes, the route links connecting the route nodes. The second map includes lanes represented as lane nodes and lane links, the lane nodes defined by latitude, longitude, and altitude, the lane links connecting the lane nodes. The route data conversion method comprises the following steps: extracting lane nodes of which the latitude, the longitude and the altitude are respectively matched with those of the route nodes; and acquiring the second route through the lane nodes extracted by the lane link connection.

Description

technical field [0001] The present invention relates to a route data conversion method, a non-transitory computer-readable storage medium, and a route data conversion device, which are used for acquiring a second route on a second map that matches a first route on a first map, so as to convert the first route on the second map The second route is linked with the first route. Background technique [0002] A known vehicle control system is based on map data (hereinafter referred to as "navigation map") by a navigation device and map data (hereinafter referred to as "high-precision map") including more detailed information than the map data stored in the navigation device Determined routes to create action plans for autonomous driving (eg, JP2017-7572A). The vehicle control system disclosed in JP2017-7572A compares the information freshness of the navigation map with that of the high-precision map based on the version and the road shape, and matches the information freshness o...

Problems solved by technology

[0004] Navigation maps often do not exactly match HD maps because the companies that provide them have different criteria for selecting roads, so that route data on a navigation device cannot be simply converted to route data on HD maps
