图像处理结果:
主要思想:
1.创建模板,建立检测区域
2.在待检测区域,使用measure_pairs检测每一对锯齿的距离
3.使用距离进行OK,NG判断
代码如下:
*基于形状匹配的检测
*测刮胡刀的锯齿,断还是没断
USING_TRANSLATE_MEASURE := 0
dev_update_window (‘off’)
*读取图像
read_image (ModelImage, ‘razors1’)
*获取图像的数据信息
get_image_pointer1 (ModelImage, Pointer, Type, Width, Height)
dev_close_window ()
*打开窗口
dev_open_window (0, 0, Width, Height, ‘white’, WindowHandle)
dev_set_part (0, 0, Height - 1, Width - 1)
*显示图像
dev_display (ModelImage)
*设置颜色
dev_set_color (‘cyan’)
*填充方式
dev_set_draw (‘margin’)
*设置线宽为2个像素
dev_set_line_width (2)
stop ()
*画
Row1 := 46
Column1 := 57
Row2 := 79
Column2 := 94
*手动画一个区域,将这个区域的图像做模板匹配
gen_rectangle1 (ROIPart1, Row1, Column1, Row2, Column2)
*手动画一个区域,将这个区域的图像做模板匹配
gen_rectangle1 (ROIPart2, Row1 + 364, Column1 + 13, Row2 + 364, Column2 + 13)

union2 (ROIPart1, ROIPart2, ModelROI)
*获得区域的中心坐标
area_center (ModelROI, Area, CenterROIRow, CenterROIColumn)
dev_display (ModelImage)
*显示模板区域
dev_display (ModelROI)
stop ()
*图像选择
reduce_domain (ModelImage, ModelROI, ImageROI)
*将刚刚上面确定的两个区域,联合起来,做为一个区域,做一个模板
create_shape_model (ImageROI, 4, 0, 0, ‘auto’, ‘none’, ‘use_polarity’, 30, 10, ModelID)
*创建形状模型的表示,可以理解为模板的骨架
inspect_shape_model (ImageROI, ShapeModelImage, ShapeModelRegion, 1, 30)
*获得模板的区域轮廓
get_shape_model_contours (ShapeModel, ModelID, 1)

dev_clear_window ()
*设置颜色
dev_set_color (‘blue’)
*显示模板轮廓
dev_display (ShapeModelRegion)
