    • A method and apparatus for reconstructing a surface shape of an object having contour lines, includes assigning points to each contour line. A first triangulation scheme is performed with respect to respective points on two adjacently-positioned contour lines, to determine a first surface shape for a portion of the object corresponding to the two contour lines. The first surface shape is checked to determine if the first surface shape is in error. If the first surface shape is not in error, the first surface shape is outputted for the portion of the object as determined by the first triangulation scheme, as a reconstructed surface shape for that portion of the object. If the first surface shape is in error, a second triangulation scheme is performed with respect to the respective points on the two contour lines, to determine a second surface shape for that portion of the object, and the second surface shape is outputted for that portion of the object as determined by the second triangulation scheme, as a reconstructed surface shape.
    • 一种用于重建具有轮廓线的物体的表面形状的方法和设备,包括将点分配给每个轮廓线。 针对两条相邻定位的轮廓线上的各个点执行第一三角测量方案,以确定对应于两条轮廓线的物体的一部分的第一表面形状。 检查第一个表面形状以确定第一个表面形状是否有误。 如果第一表面形状没有错误,则将由第一三角测量方案确定的对象部分的第一表面形状输出为该对象部分的重建表面形状。 如果第一表面形状出错,则关于两条轮廓线上的各个点执行第二三角测量方案,以确定物体的该部分的第二表面形状,并且针对该部分输出第二表面形状 由第二三角测量方案确定的物体的重建表面形状。
