halcon 模型生成点云、深度图生成点云
用halcon生成一个均匀的球
思路：
1 、下采样（推荐）
2、 三角化骨骼顶点（不推荐）
* This example program shows how to use the operators
* gen_plane_object_model_3d, gen_sphere_object_model_3d_center
* gen_sphere_object_model_3d, gen_cylinder_object_model_3d, and
* gen_box_object_model_3d in HALCON. In this example, a plane,
* two spheres, a cylinder, and a box are set with different poses.
* The generated primitves of the 3D object models are visualized.
*
* Initialize program.

X := 3 * Row / max([Row,Column]) - 2

*
* Create an infinite plane.
gen_plane_object_model_3d ([0,0,0,0,0,0,0], [], [], ObjectModel3DPlane1)
* Create a limited plane.
gen_plane_object_model_3d ([1,1,1,0,50,30,0], X, Y, ObjectModel3DPlane2)
* Create a sphere using pose.
gen_sphere_object_model_3d ([0,0,3,0,0,0,0], 0.5, ObjectModel3DSphere1)
gen_sphere_object_model_3d ([0,0,0,0,0,0,0], 5, ObjectModel3DSphere)
* Create a sphere und position.
gen_sphere_object_model_3d_center (-1, 0, 1, 1, ObjectModel3DSphere2)
* Create a cylinder.
gen_cylinder_object_model_3d ([1,-1,2,0,0,60,0], 0.5, -1, 1, ObjectModel3DCylinder)
gen_cylinder_object_model_3d ([1,-1,2,0,0,60,0], 1, -2, 2, ObjectModel3D)
* Create a box.
gen_box_object_model_3d ([-1,2,1,0,0,90,0], 1, 2, 1, ObjectModel3DBox)
*
* Display the generated primitives.

* 不推荐 拿到的点其实就是三角化之后三角形的顶点----骨骼
convex_hull_object_model_3d (ObjectModel3DSphere, ObjectModel3DConvexHull)
* 得到球面上的点

下采样：
深度图生成点云
* 加载图像;
dev_close_window ()
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
read_image (Image7, 'C:/Users/Albert/7 没检测出来/7.tif')
threshold(Image7, Region, -45, 255)
get_domain (Image7, Domain)
difference (Domain, Region, RegionDifference)
paint_region (RegionDifference, Image7, ImageResult, -40, 'fill')
* 有nan 值先取掉
min_max_gray (ImageResult, ImageResult, 0, Min, Max, Range)
threshold (ImageResult, Region1, Min, Max)
reduce_domain (ImageResult, Region1, ImageReduced)
get_image_size (ImageReduced, Width, Height)
* 生成xy 图
gen_image_surface_first_order (ImageSurface, 'real', 1, 0, 0, 0, 0, Width, Height)
gen_image_surface_first_order (ImageSurface1, 'real', 0, 1, 0, 0, 0, Width, Height)
x:=1
y:=2
z:=1
scale_image (ImageSurface, X, x, 0)
scale_image (ImageSurface1, Y, y, 0)
scale_image (ImageReduced, Z, z, 0)
* 生成点云模型
xyz_to_object_model_3d (X, Y, Z, ObjectModel3D)
write_object_model_3d (ObjectModel3D, 'ply', 'C:/Users/Albert/Desktop/mycloud', [], [])
gen_image_surface_first_order 使用一阶多项式创建倾斜的灰色曲面
