halcon图像变形-ROI区域旋转
关键算子:
orientation_region
vector_angle_to_rigid
affine_trans_region
测试图片:
halcon代码:
-
*此例子将图中没有偏移的形状参照旋转的形状进行旋转
-
read_image (Image, 'D:/Halcon-WorkSpaces/Test/Image/test14.png')
-
rgb1_to_gray (Image, GrayImage)
-
*获取旋转的矩形
-
threshold (GrayImage, Regions, 0, 0)
-
*计算区域斜率
-
orientation_region (Regions, Phi)
-
*获取没有旋转的矩形
-
threshold (GrayImage, Regions1, 100, 140)
-
area_center (Regions1, Area, Row, Column)
-
*创建变换模型
-
vector_angle_to_rigid (Row, Column, 0, Row, Column, Phi, HomMat2D)
-
*区域变换
-
affine_trans_region (Regions1, RegionAffineTrans, HomMat2D, 'nearest_neighbor')
-
dev_clear_window ()
-
dev_display (RegionAffineTrans)
-
dev_display (Regions)
