halcon 焊点检测案例

*循环读入图片
list_files('F:/halcon_test/circularity_die', 'files', Files)
tuple_regexp_select (Files, '.png', Imagefiles)
for imgIndex := 0 to |Imagefiles| -1 by 1
    read_image (Image, Imagefiles[imgIndex])
    *根据灰度生成感兴趣区域
    min_max_gray (Image, Image, 0, Min, Max, Range)
    threshold (Image, Region,Max-80 , Max)
    shape_trans (Region, RegionTrans, 'rectangle2')
    reduce_domain (Image, RegionTrans, ImageReduced)
    *选择焊点
    min_max_gray (RegionTrans, ImageReduced, 0, Min, Max, Range)
    threshold (ImageReduced, Region1, Min, Min+30)
    *形态学操作滤除孤立点
    opening_circle (Region1, RegionOpening,10)
    *多特征选择
    connection (RegionOpening, ConnectedRegions)
    select_shape (ConnectedRegions, SelectedRegions, ['rectangularity','circularity'], 'and', [0,0.5427], [0.8573,0.94944])
    dev_clear_window ()
    dev_display(Image)
    dev_display (SelectedRegions)
    stop()

endfor
