Patent Images
1. A system for sparse map autonomous navigation of a vehicle along a road segment, the system comprising:
- at least one processor programmed to;
receive a sparse map of the road segment, wherein the sparse map has a data density of no more than 1 megabyte per kilometer and the sparse map includes a three-dimensional polynomial representation of a target trajectory for the vehicle to traverse along the road segment;
receive from a camera, at least one image representative of an environment of the vehicle;
analyze the sparse map and the at least one image received from the camera; and
determine an autonomous steering action for the vehicle based on the analysis of the sparse map and the at least one image received from the camera.

Abstract
A system for sparse map autonomous navigation of a vehicle along a road segment may include at least one processor. The at least one processor may be programmed to receive a sparse map of the road segment. The sparse map may have a data density of no more than 1 megabyte per kilometer. The at least one processor may be programmed to receive from a camera, at least one image representative of an environment of the vehicle, and determine an autonomous navigational response for the vehicle based on the analysis of the sparse map and the at least one image received from the camera.
