Stability and Correlation Analysis of Data Obtained by Contact and Non-Contact Measuring Body
Today, high technology is transforming traditional industry. The science, suitable measuring technique and data application method are the basis of large-scale manufacture realizing, which not only meet individual consumer demand, but also are meaningful to raise the economic efficiency and reduce production cycle of custom-made. Custom-made enterprise always has its own contact measuring method and mechanism, which uses uniform size clothing to wear or measurement by manual re-confirm to obtain data.The efficiency of this method is low and its accuracy is poor. But non-contact measuring method has problems in application of equipment and can not completely replace manual operation. How make manual measuring method and laser measuring instruments work together to get data is the demand of practical management and production improvement in enterprise, but there is no data standard between the two methods. This research based on national size standard and professional normative measuring method, and used manual and three-dimensional laser measuring ways to collect sample data in identical situation. Under designed data standard, the research used mathematical statistics to analyse data, and then made comprehensive assessment in aspects of instrumental stability and data correlation. This paper is the case of practical application, among which used to study the tolerance range of the standard data was initial issue (sci-tech novelty report was attached).
