Patent ID: 7313506

Claim:
A method for visibly identifying a position at a construction site of a user selected specific location of interest within a three-dimensional model of a structure to be constructed at that site, the method comprising the steps of: scanning a site with a laser scanner to create a field survey, the field survey having a number of scan points; designing a three-dimensional model of the structure to be constructed at the site using the scan points from the field survey of the site, the three-dimensional model of the structure having a number of defined points that are positionally related to the scan points in the field survey; rescanning the site with the laser scanner to obtain rescan data, the rescan data corresponding to at least a portion of the number of the original scan points; registering the rescan data with the defined points from the three-dimensional model of the structure in order to form registered data of the structure to be constructed; and thereafter illuminating a position at the site with a visible laser beam from the laser scanner that corresponds with a user selected specific location of interest within the three-dimensional model of the structure.
