* ***********************************************************************
* This example program shows how to use the operator
* segment_object_model_3d in HALCON. First, the 2.5D
* input image is segmented. Additionally, with the same
* operator, a fitting is performed. The result of the
* 3D segmentation is converted to a region and is
* displayed. Finally, the values of the fitted radii
* for the cylinders and spheres are visualized.
* 首先，分割2.5D输入图像,转化为适当的3D Model,
* 并分割成sub Models(segment_object_model_3d),sub Models转化为区域并显示。
* 最终，圆柱形和球形标示半径并图形化显示。
