O modelo Halcon gera uma nuvem de pontos e o mapa de profundidade gera uma nuvem de pontos

Gerar uma bola uniforme com halcon

Ideias:

1. Redução da resolução (recomendado)

2. Vértices ósseos triangulares (não recomendado)

* 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.

* 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 cria superfícies cinzas inclinadas usando polinômios de primeira ordem
