逆向工程中对测量数据进行重定位的研究

摘要

In reverse engineering measuring,the part whose appearance is complex or whose dimension is very large is often encountered.Because of the restriction of metrical device,the data measure in different coordinate systems is often needed,then the reposition of the data measured must be solved.The optimum method of multi-target and multi-parameter is put forward in this paper.Its reposition precision is greatly advanced with regarding other traditional algorithms.The fundamental of this research is that rough reposition of the data measured is done firstly,which is equal to looking for the solvable range of optimum method,then the data measured are accurately repositioned with the method of multi-target and multi-parameter,which is equal to looking for the optimum solution of optimum method.
