Abstract

The invention provides a digital model rectification. A system includes a computer that includes a processor and a memory storing instructions executable by the processor to decompose a stored map ofan area into a plurality of polygonal sub-areas. The instructions include instructions to generate a set of target locations in the polygonal sub-areas according to a leaky ball algorithm. The instructions include instructions to actuate a robot to move to a first one of the target locations of the set. The instructions include instructions to actuate a sensor to collect data at the first one of the target locations.

Description

technical field [0001] The present disclosure relates generally to vehicle navigation, and more particularly to the use of robots to assist in vehicle navigation. Background technique [0002] An unmanned vehicle or robot may be deployed in an area to obtain data about the area (eg, map data) and data about objects in the area. However, there are questions about the operation of such robots. For example, often a robot may at most be provided with incomplete and / or out-of-date map data for an area, e.g. boundaries or obstacles (such as walls, stairs, etc.) may have been moved, added or removed since the map was last updated . Additionally, objects (such as equipment, furniture, etc.) may have been added, removed, or moved. Based on such altered, incomplete and / or inaccurate data, operating a robot to navigate to a proper position and / or pose in order to obtain data about objects and / or map data presents challenges. Contents of the invention [0003] A system includes a ...
