Claim Text:
1. A method of calibrating a laser measurement system in-situ, wherein the laser measurement system includes a laser scanner having synch pulses and a base line within said laser scanner, comprising the steps of: a) placing a scanner in a location having at least two random targets; b) using the scanner to scan the at least two random targets to create a first set of data; c) storing said first set of data; d) repositioning the scanner; e) using the scanner to scan each of said at least two random targets to create a second set of data; f) comparing said first and second sets of data to determine a true position of each of said at least two random targets and to create a correction factor for said scanner such that the synch pulses are coordinated and the base line of the scanner is a true base; wherein the step of comparing said first and second sets of data, further includes the steps of: g) interpolating said first and second sets of data; and h) correcting a synch pulse generated by said scanner using the correction factor such that the synch pulses are coordinated and the base line of the scanner is a true base.
