halcon模板匹配、由点生成线应用

halcon模板匹配、由点生成线应用

1、图片链接：https://pan.baidu.com/s/1ZTenkUDgiDIBCYp-xFwV8A

2、要求：
（1）利用果实和叶子制作模板并且定位（模板必须完整无分支干扰线）；
（2）叶子和果实 重心通过仿射变换显示在logo上；
（3）计算叶子与果实重心连线基于模板重心的连线的角度；
3、代码实现：

dev_get_window (WindowHandle)

read_image (Image, './logo/1.jpg')
flag:=1
if(flag=0)
    draw_rectangle1(WindowHandle, Row1, Column1, Row2, Column2)
    gen_rectangle1 (ROI_0, Row1, Column1, Row2, Column2)
    reduce_domain (Image, ROI_0, ImageReduced)
    create_shape_model(ImageReduced, 'auto', 0, rad(360), 'auto', 'auto', 'use_polarity', 'auto', 'auto', ModelID)
    get_shape_model_contours(ModelContours, ModelID, 1)
    dev_display (Image)
    dev_set_draw('margin')
    write_shape_model(ModelID,'model2.shm')
    write_string(WindowHandle,'模板创建完毕!')
endif


if(flag=1)
    for  i:= 1 to 12 by 1
        read_image (Image1, './logo/'+i+'.jpg')
