The Surface Measurement Technology And Application Of Reverse Engineering

Reverse Engineering plays an increasingly important role in create and develop a new product by digesting and absorbing advanced technologies.How to acquire a large quantity of coordinate points efficiently and accurately has become a critical issue in RE. The intelligent measuring system with multi-sensors integration technology will be the most promising trend for free-form surface measurement.How to utilize CCD in surface measurement and how to apply the results that feature the surface of the object to instruct higher resolution sensors for furthereasuring has been studied.In this paper, some relevant research work has been made on the basis of the existing literature on RE of the surface measurement technology and its applications.First summarizes the important role of RE,it is a brief introduction of modern-contact measurement methods,as well as vision-based technology, non-contact measurement of free-form surface,and summarized the development trend of three-dimensional measurement systems,described RE technology and its application of critical need for research;thus gives the topics of papers basis.Then proposed based on the CCD surface binocular stereo vision measurement method,and described the basic measurement principle of the method;study of a non-contact measurement of the CCD,and through physical measurements to be verified;details of the data pre-processing of the relevant theory;and in the traditional measurement method based on the analysis put forward under the guidance of visual information based on rapid measurement of rectangular segments,and policy analysis of the method.
