结构光三维物体面形实时测量系统

A REAL-TIME DETECTION SYSTEM OF 3-D OBJECT USING STRUCTURE LIGHT TECHNIQUE

本文基于结构光投影方法提出了一种新的三维物体面形重建方法，并建立了三维物体面形实时测量系统，系统用硬件电路实现结构光峰值提取，然后由软件对畸变光条峰值分布进行总体面形拟合处理。处理中，可以获得物体在视场内附加了一个倾斜面的三维物体面形分布。物体实际面形可以通过减去这个附加倾斜面而获得。

n this paper,a new method for the reconstruction of 3-D object is proposedbased on structure light casting technique,A real-time detection system of 3-D objectusing this technique is constructed. The feature of the structure light are extracted bythe hardware. The object shape is processed using overallshape least-squares method.The shape obtained is the object shape added an inclined surface. The real shape ofthe object can be obtained by subtracting the inclined surface.
