Abstract: Systems and methods for projecting a three-dimensional (3D) surface to a two-dimensional (2D) surface for use in autonomous driving are disclosed. In one aspect, a control system for an autonomous vehicle includes a processor and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: receive a 3D map including a plurality of objects, determine a base point in the 3D map, shift the objects in the 3D map based on the base point, project the objects in the shifted 3D map to a 2D map, and output the 2D map.

Abstract: A method of constructing a map including a plurality of lanes and a system thereof are provided. The method includes: for each of the plurality of lanes, constructing corresponding lane geometry data based on a plurality of polyline segments, including constructing a general outline circumscribing the plurality of lanes and identifying an outline of each of the plurality of lanes based on the plurality of polyline segments and the general outline. Outline polyline segments as boundaries of the general outline are selected from the plurality of polyline segments.
