1.get_image_size(Image : : : Width, Height)
返回图像的尺寸。
2.parameters_image_to_world_plane_centered (CamParam, Pose, CenterRow, CenterCol, WidthMappedImage, HeightMappedImage, ScaleForCenteredImage, PoseForCenteredImage)
Halcon内部程序，输出为图像的比率和姿态。
3.gen_image_to_world_plane_map( : Map : CameraParam, WorldPose, WidthIn, HeightIn,WidthMapped, HeightMapped, Scale, MapType : )
产生一个投影映射，该映射描述图像平面与Z=O的世界平面之间的关系，输出为图像MAP，是一个多通道的图像
包含了映射数据。
4.map_image(Image, Map : ImageMapped : : )
利用映射变换校正图像，输出为矫正后的图像。
5.image_to_world_plane(Image : ImageWorld : CameraParam, WorldPose, Width, Height, Scale,Interpolation : )
把校正后的图像转换到Z=0的世界平面。
6.image_points_to_world_plane( : : CameraParam, WorldPose, Rows, Cols, Scale : X, Y)
把图像上的点转换到Z=0的世界平面，输出为点坐标。
