halcon-union2_closed_contours_xld封闭轮廓

在HDevelop中

dev_close_window ()
read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray (Image, GrayImage)

edges_sub_pix (GrayImage, Edges, 'canny', 1, 5, 10)
*亚像素边缘

union2_closed_contours_xld (SelectedXLD, SelectedXLD, ContoursUnion)
*封闭轮廓
*参数1和参数2就一个轮廓时，轮廓端点直接连线封闭
*参数3：输出轮廓

union2_closed_contours_xld (SelectedXLD, SelectedXLD1, ContoursUnion1)
*参数1和参数2是两个轮廓时，就近封闭
