halcon--Region Of Interest

3.1 Basic Concept

read_image (Image, 'mreut')
gen_circle (ROI, 256, 256, 200)

reduce_domain (Image, ROI, ImageReduced)
edges_sub_pix (ImageReduced, Edges, 'lanser2', 0.5, 20, 40)
dev_display (Image)
dev_display (ROI)
dev_display (Edges)

 

reduce_domain (Image, ROI, ImageReduced)
提取感兴趣区域,输入是一个image和一个region,输出是一个image(输入的交集)
然后之后的处理都基于ROI,以节约cpu

edges_sub_pix
提取亚像素精度轮廓
