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)
