First Claim
1. 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
thereafterilluminating 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.

Abstract
A laser scanning system can be used in construction projects to generate a field survey. An architect or engineer can use the field survey to create construction drawings. In addition, relevant points from the construction drawings can be identified at the construction site with the scanning system. Further, earth moving equipment can be controlled using the same information. The laser scanning system can be used to determine if two parts can be mated together by scanning and comparing the parts that are to be mated. The laser scanning system can further be used to determine if an object can be moved through an opening in a structure by comparing scan points of the structure with scan points from the object. The laser scanning system can be used to identify objects within the site, to build databases that have relevant information about the objects, and to guide reproducing machines.

8. A method for monitoring construction of a structure at a site, 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
thereafterilluminating the site with a visible laser beam from the laser scanner in order to trace out key features of the structure as the structure is being constructed in order to determine variations between the structure and the three-dimensional model of the structure during construction. - View Dependent Claims (9, 10, 11, 12, 13)
