摘　　要：利用三坐标测量机测量了电话听筒的几何外形,获取了几何表面的外形数据点群;利用逆向工程软件对点群数据进行消除噪声、数据重采样及提取特征线等处理;根据外形特征,从点群数据中提取其边界曲线;采用由点和曲线形成曲面的造型方法,成功进行了电话听筒三维几何曲面模型的重构。The digital point groups of geometrical surfaces of the telephone receiver were obtained through measuring with a three coordinates measming machine. Using reverse engineering software, Imageware, the scanning data point groups were processed, including of eliminating noise, resampling the scanning data and extracting the feature lines. Based on the shape features of the telephone receiver, the boundary curves were picked up from the scanning data point groups. The 3-dimensional models of the telephone receiver were reconstructed with the boundary curves and the scanning data point groups.
