Halcon tiff 点云读取以及平面矫正_halcon 点云平面校准

一、读取tiff 图

 
dev_close_window ()
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
 
xResolution:=0.0025
yResolution:=0.0025
zResolution:=0.001
read_image (IntputImage, 'C:/Users/alber/Desktop/2023-08-15_16-38-24-982_/Sta5_002.tif')
zoom_image_factor (IntputImage, IntputImage, 1,4, 'constant')
get_domain (IntputImage, Domain)
*获取该区域的最大最小值
min_max_gray (Domain, IntputImage, 0, Min, Max, Range)
*去除无效数据
threshold (IntputImage, Region,-1.2, Max)
reduce_domain (IntputImage, Region, ImageReduced)
 
get_image_size (ImageReduced, Width, Height)
convert_image_type (ImageReduced, ImageConvertedX, 'real')
*生成xy坐标的图像映射，乘以分辨率就是xy的相对值
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)
scale_image (ImageSurface, X, xResolution, 0)
scale_image (ImageSurface1, Y, yResolution, 0)
 
*创建3D模型
xyz_to_object_model_3d (Y,X,ImageReduced, ObjectModel3D)
write_object_model_3d (ObjectModel3D, 'ply', 'C:/Users/alber/Desktop/abc.ply', [], [])
disp_object_model_3d (WindowHandle, [ObjectModel3D], [], [], ['color_0','alpha'], ['green',0.7])

二、平面矫正

用Z轴来矫正

 
select_points_object_model_3d (ObjectModel3D, 'point_coord_x', 2.73, 3.2, ObjectModel3DThresholded)
select_points_object_model_3d (ObjectModel3DThresholded, 'point_coord_y', 1, 3.4, ObjectModel3DThresholded)
fit_primitives_object_model_3d (ObjectModel3DThresholded, ['primitive_type','fitting_algorithm'], ['plane','least_squares_tukey'], ObjectModel3DOut)
 
* 这一步很重要
get_object_model_3d_params (ObjectModel3DOut, 'primitive_parameter_pose', pose)
 
 
 *用Z轴来矫正
 * 将旋转的角度转转回去
 pose[3]:=-pose[3]
 pose[4]:=-pose[4]
 pose[5]:=-pose[5]
write_object_model_3d (ObjectModel3DThresholded, 'ply', 'C:/Users/alber/Desktop/abc3333.ply', [], [])
*
rigid_trans_object_model_3d (ObjectModel3DThresholded, pose, ObjectModel3DRigidTrans)
write_object_model_3d (ObjectModel3DRigidTrans, 'ply', 'C:/Users/alber/Desktop/abc3333afffff.ply', [], [])
 
 
rigid_trans_object_model_3d (ObjectModel3D, pose, ObjectModel3DRigidProdUCE)
write_object_model_3d (ObjectModel3DRigidProdUCE, 'ply', 'C:/Users/alber/Desktop/ABC_CR.ply', [], [])

三、 从一个姿态转到指定的姿态

1、将原始姿态pose ->matrix1

2、将指定的姿态pose 2->matrix2

3、svd  矩阵分解，计算出两个姿态的差接矩阵M

4、矩阵-》pose

5、rigid_trans_object_model_3d

矫正前：

矫正后：

：

 
dev_close_window ()

xResolution:=0.0025
yResolution:=0.0025
zResolution:=0.001
read_image (IntputImage, 'C:/Users/alber/Desktop/2023-08-15_16-38-24-982_/Sta5_002.tif')
zoom_image_factor (IntputImage, IntputImage, 1,4, 'constant')
get_domain (IntputImage, Domain)
*获取该区域的最大最小值
min_max_gray (Domain, IntputImage, 0, Min, Max, Range)
*去除无效数据

reduce_domain (IntputImage, Region, ImageReduced)
 
get_image_size (ImageReduced, Width, Height)
convert_image_type (ImageReduced, ImageConvertedX, 'real')
*生成xy坐标的图像映射，乘以分辨率就是xy的相对值
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)
scale_image (ImageSurface, X, xResolution, 0)
scale_image (ImageSurface1, Y, yResolution, 0)
 
*创建3D模型
