Halcon-模板匹配（WPF）

halcon的代码

dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
read_image (Image, 'C:/Users/CF/Desktop/image.jpg')
dev_display (Image)

draw_rectangle1 (WindowHandle, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
reduce_domain (Image, Rectangle, ImageReduced)
crop_domain (ImageReduced, ImagePart)


create_shape_model (ImagePart, 'auto', -0.39, 0.79, 'auto', 'auto', 'use_polarity', 'auto', 'auto', ModelID)

write_shape_model (ModelID, 'C:/Users/CF/Desktop/shapeModel1.shm')

find_shape_model (ImagePart, ModelID, -0.39, 0.79, 0.5, 1, 0.5, 'least_squares', 0, 0.9, Row, Column, Angle, Score)
