Abstract
A system includes a processor and a memory. The memory stores instructions executable by the processor to generate, from LIDAR data, a first intensity map of an area around a vehicle, and to estimate a vehicle location based on comparing the first intensity map to a grayscale top view image.
Claims20
A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- generate, from three-dimensional LIDAR data obtained from a vehicle LIDAR sensor, a first two-dimensional intensity map of an area around a vehicle;
- estimate a location of a vehicle based on comparing the first two-dimensional intensity map to a second two-dimensional intensity map generated from a grayscale top view image obtained from a sensor external to the vehicle;
- and
- operate the vehicle based on the estimated location.

A system, comprising:
- a LIDAR sensor for a vehicle;
- and
- a processor and a memory, the memory storing instructions executable by the processor to:
- generate, from three-dimensional LIDAR data obtained from the LIDAR sensor, a first two-dimensional intensity map of an area around the vehicle;
- receive, from a remote computer, a grayscale top view image captured by a sensor external to the vehicle;
- estimate a location of the vehicle based on comparing the first two-dimensional intensity map to a second two-dimensional intensity map generated from the grayscale top view image;
- and
- operate the vehicle based on the estimated location.
