halcon与C混合编程数字识别
示例：数字识别
要识别的图片：
halcon源码：
1: *读取图片
2: read_image(Image,'D:/MyFile/halcon/数字识别/')
3:?
4: *图像处理
5: decompose3(Image, ImageR, ImageG, ImageB)
6: threshold (ImageG, Regions, 0, 183)
7: connection (Regions, Connection)
8:?
9:select_shape (Connection, SelectedRegions, 'area', 'and', , 7500) 10:?
11: read_ocr_class_mlp('',OCRHandle)
12: do_ocr_multi_class_mlp(SelectedRegions,ImageG,OCRHandle, Class, Confidence)
halcon导出的C#代码：
1:pg*|BMP文件|*.bmp*|TIFF文件|*.tiff*";
30:?
31: = true;
32:?
33: = 1;
34:?
35:if () ==
36:?
37: {
38:?
39: ImagePath = ;
40:
41: , ImagePath);
42:
43: = true;
44:
45: }
46: }
47:?
48:private void btnRecognitionNumber_Click(object sender, EventArgs e)
49: {
50: ();
51: = 52:?
53: = false;
54: }
55: }
56:?
