摘　　要：三维光学测量系统结合了数字近景摄影测量技术和结构光栅空间编码测量技术,同时具备摄影测量效率高和光栅测量精度良的优点。利用三维光学测量数据进行建模,可以很好地重构出原始物件的表面形状,在现代工业中有着不可替代的作用。利用三角形生长法生成点云数据的不规则格网的方法,构建其数据模型,通过CAD的二次开发实现其显示功能,研究表明:该软件能很好地重现物件的表面特征,建模精度高,可应用于三维光学测量的建模。Three-dimensional optical system measurement is a system which combined with digital close shot monitoring technology with structure fringe space coding measurement technology,and it has merits of high efficiency in photogrammetry and good accuracy in structure fringe measurement at the same time.Using 3-dimensional optical measurement data for modeling,can reconstruct surface shape of original items,in this way,it plays an irreplaceable role in modern industry.This paper would apply triangle growing low to develop point cloud data,to construct data model and to realize display function by using CAD secondary development.The achievement shows that this software can re-construct surface characters of items well with high accuracy of modeling and can be applied in 3-D optical measurements.
