摘要:
基于零件实物样件的几何模型反求技术已成为CAD/CAM领域的研究热点之一,现提出一种基于面结构光投影法的复杂零件轮廓表面检测与三维重构技术.此技术通过向被测物体表面投射条纹光栅,得到包含物体表面形状的畸变条纹,畸变条纹图像由CCD拍摄并传送至计算机,通过对畸变条纹图像的分析处理,得到被测物体表面的三维外形数据信息.根据检测得到的三维点云数据的特点,用基于曲率抽样的拓扑矩形阵列进行了NURBS曲面拟合.实验结果表明基于面结构光投影法的重构系统具有检测准确、快捷、非接触等特点,且能对复杂零件外形进行有效检测与三维重构.
Abstract:
The reverse engineering of geometric model based on pat exemplar has become one of the research focuses in CAD/CAM field. This paper presents the methods of 3D shape measurement and reconstruction based on surface. The measurement principle is deduced and the mathematics model is established. The deformed grating pattern appears when the standard grating pattern is projected onto the specimen. The deformed grating pattern image contains information about the surface topography of 3D object. The deformed grating pattern is input into a computer by CCD camera and processed by a series of procedures to obtain the digital point clouds of geometrical surfaces of the measured object. According to 3D shape measured data,non-uniform rational b-spline ( NURBS) surface fitting based on an extracted topology array is made. Experimental result shows that the system can realize 3D shape measurement and reconstruction of complex surface.
