1. A method of acquiring a three-dimensional surface image of at least one object using a range camera, comprising the steps of:
- receiving operator defined parameters;
calculating a number of scans required for the range camera to scan the at least one object in accordance with optical parameters for the range camera and the operator defined parameters;
controlling the range camera to perform the calculated number of scans, the scans generating scan data for each of the calculated number of scans; and
, merging the generated scan data to form the three-dimensional surface image of the at least one object.

Abstract
A method of acquiring a three-dimensional surface image of an object using a range camera automatically calculates an optimal number of scans. The optimal number of scans is calculated in accordance with operator-defined and camera optical parameters. Scan data acquired for each scan is merged with a preference for higher resolution data over lower resolution data for any given scanned area, such that the merged scan data forms the three-dimensional surface image of the object.
