A Review of Multiple-sensor Combination Measuring System in Reverse Engineering

Part digitization is the first step in reverse engineering,and its precision,efficiency,and data integrity of the work-piece greatly influence the construction of the CAD model.Multiple-sensor combination measuring system(MCMS) is of great importance to improve the efficiency and the precision of digitization.We first review the methods of part digitization in reverse engineering and the development of MCMS.We draw the conclusion that the increasing demand on flexibility and automation of the digitization process can be satisfied by MCMS,and the shortcomings of a single sensor measuring system can also be overcome by MCMS.Finally,three problems that need to be solved in the application of MCMS to reverse engineering are pointed out.
