Design of the Reference Points when Using3D Optical Measurement System in Reverse Engineering and Research on the Image Processing and Recognition Techniques

摄影测量作为反向工程中一种可靠的数据获取方式逐步运用在模具设计与制造中。通过将摄影测量和光栅测量方法相结合 ,可以使光栅测量要用到的标志参考点进行全额的自动匹配 ,大大加快了光栅测量法中点云的获取 ,并且保证了测量的准确性。主要阐述了摄影测量中编号参考点的设计以及利用matlab工具对其进行图像处理和识别的相关技术。

Photogrammetry,as a reliable method for data attainment in reverse engineering,has been gradually applied in the design and manufacture of dies and moulds in recent years.The mark reference points to be used in raster measurement can be completely and automatically matched by combining photogrammetry and raster measurement methods,which greatly speeds up the attainment of clouds data by raster measurement method and ensures the measurement precision.The design of the code reference points for photogrammetry and the related techniques of image processing and recognition of the points with matlab are mainly introduced.
