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.
