Abstract

A method for generating a road map for vehicle navigation and decision comprises: providing original road image data having an image of a road; identifying boundary lines defining respective lane segments of the road from the original road image data; associating traffic properties with the lane segments defined by the boundary lines, respectively; grouping the lane segments to generate road segments; and combining the road segments with traffic control objects corresponding thereto so as to generate the road map for vehicle navigation.

Description

[0001] Cross References to Related Applications [0002] This application is related to U.S. Provisional Application 62 / 649,573, filed March 29, 2018, and U.S. Application 16 / 359,991, filed March 20, 2019, entitled: "METHOD FOR GENERATING ROAD MAP FORVEHICLE NAVIGATION AND NAVIGATION DEVICE ”, the disclosures of these patent applications are incorporated herein by reference in their entirety. technical field [0003] The present application relates generally to navigation and digital mapping technologies and, in particular, to a method of generating detailed machine-readable road maps for autonomous driving navigation and decision-making systems. Background technique [0004] Vehicle navigation allows the driver of a car to see his or her location on a map. Typically, a satellite navigation device or an inertial measurement unit (such as an accelerometer or gyroscope sensor) can be used to obtain the vehicle's position, so that when directions are required, a route can be c...
