1.引言 日趋激烈的国际性经济竞争,迫使各国的诸多公司、生产厂家采用CAD/CAM和FMS/CIMS来设计制造新产品。作为开发新产品的初始测量和测试等技术也随之显得越来越重要。因此,世界各工业发达国家都十分注重发展测量技术,尤其是曲面测量技术,并且正朝着发展测量加工一体化技术的方向迈进。 测量技术发展至今天,用于测量曲面的方法大致有:三坐标机测量法、全息测量法、摄影测量法、半球头测量法、光栅投影测量法、光外差测量法、电子经纬仪交绘测量法、激光
1. Introduction The increasingly fierce international economic competition has forced many companies and manufacturers in various countries to design and manufacture new products using CAD / CAM and FMS / CIMS. As the development of new products, such as the initial measurement and testing technology will become more and more important. Therefore, all industrialized countries in the world place great emphasis on the development of measurement technology, especially the surface measurement technology, and are moving forward in the field of integrated measurement and processing technology. Measurement techniques developed today, the methods used to measure the surface are generally: CMM, holographic, photogrammetry, hemispherical head measurement, grating projection measurement, light heterodyne measurement, electronic theodolite cross-mapping measurement Law, laser
