Abstract
Aspects of the present disclosure relate generally to systems and methods for assessing validity of a map using image data collected by a laser sensor along a vehicle path. The method may compile image data received from the laser sensor. The map subject to assessment may define an area prohibiting entry by a vehicle.
Claims17
A method for assessing validity of a map, comprising:
- receiving a compressed image describing a path of a vehicle through an area, wherein the compressed image is an image derived from image data collected by a sensor;
- reconstructing, by one or more processors, the compressed image to form a first image;
- identifying, by the one or more processors, a map related to the area;
- displaying, by the one or more processors, the first image in relation to the map, by overlaying the first image on top of the map such that same objects appearing in both the first image and the map appear at same geographical areas, and determining whether one or more discrepancies exist between the map and the first image;
- assessing, by the one or more processors, validity of the map based on the display of the first image in relation to the map;
- and
- maneuvering the vehicle based on the assessed validity of the map.

A method for assessing validity of a map, comprising:
- determining, by one or more processors a current location of a vehicle, using a sensor of the vehicle;
- identifying, by the one or more processors, a map related to the current location of the vehicle, the map including an area prohibiting entry for travel;
- determining, by the one or more processors, whether the map includes a plausible location unobstructed for travel when the area prohibiting entry for travel overlaps with the current location of the vehicle;
- assessing, by the one or more processors, validity of the map based on the determination;
- maneuvering the vehicle based on the assessed validity of the map;
- and
- transmitting a signal indicating that the map is invalid when the map does not include the plausible location consistent with the current location of the vehicle.
