Abstract: A scanning measurement systems for the repair of structures that includes laser base or hub assembly. The laser base assembly serves as a single rotating head emitting a pair of laser beams, and may include a device for detecting a reflected signal (if using retroreflective targets) such as an array of photo diodes, for example, and a system for transmitting this detected signal to a computer that analyzes the signals. One use of the system is to determine the amount of deformation from a manufacturer's standards of a structure such as a vehicle frame. The system provides a compact and cost-effective way to determining the deformation of various portions of the structure and a monitoring system to display real-time data as the structure is being changed (repaired). The system can be used to show a work plan for an estimate, or a detailed report of all changes made to the structure.

Abstract: An improved laser scanning apparatus (46) for determining frame or unibody alignment or misalignment of a vehicle (40) is provided, which includes a laser assembly (54), a pair of rotatable mirror assemblies (56,58) and laser detectors (114,116) located within an enclosed housing (50,52). The laser assembly (54) has an upper pair of lasers (122,126) located in known, spaced relationship above a lower pair of lasers (124,128); detector assemblies (114, 116) are also provided including substantially parabolic reflective surfaces (118a, 120a) with detectors (114a, 116a) disposed substantially at the focal point of the surfaces (118a, 120a). The apparatus (46) is used in conjunction with a plurality of individually coded reflective targets (44) which are suspended from known reference points on the vehicle (40).
