Two-dimensional mapping system and method of operation
First Claim
1. A method of generating a two-dimensional (2D) map, the method comprising:
- acquiring coordinate data of points in an area being scanned with a mobile optical scanner;
generating a current 2D map from the coordinate data;
saving a copy of the current 2D map on a periodic or aperiodic basis;
identifying at least one data registration error in the current 2D map;
determining the saved copy of the current 2D map from a point in time prior to the registration error;
identifying a second data set of coordinate data acquired after the determined saved copy;
aligning the second data set to the determined saved copy to form a new current 2D map; and
storing the new current 2D map.

Abstract
A method and system of generating a two-dimensional map with an optical scanner is provided. The method comprises acquiring coordinate data of points in an area being scanned with a mobile optical scanner. A current 2D map from the coordinate data is generated. A copy of the current 2D map is saved on a periodic or aperiodic basis. At least one data registration error is identified in the current 2D map. The saved copy of the current 2D map from a point in time prior to the registration error is determined. A second data set of coordinate data acquired after the determined saved copy is identified. The second data set is aligned to the determined saved copy to form a new current 2D map. The new current 2D map is stored in memory.

6. A method of generating a two-dimensional map with a scanner, the method comprising:
-
acquiring a first set coordinate data with an optical scanner; determining a predetermined amount of time has elapsed or a predetermined distance has been scanned; storing in memory of a processor operably coupled to the optical scanner a first copy of a two-dimensional map generated from the first set of coordinate data acquired during the predetermined amount of time or the predetermined distance; acquiring a second set of coordinate data with the optical scanner; generating a current two-dimensional map based at least in part on the first set of coordinate data and the second set of coordinate data; determining a registration error in the current two-dimensional map; determining the first copy does not include the registration error; registering the second set of coordinate data with the first copy; and replacing the current two-dimensional map with a new two-dimensional map based at least in part on the registration of the second set of coordinate data to the first copy. - View Dependent Claims (7, 8, 9, 10, 11, 12)
