Example Embodiment
[0109] Example 1
[0110] 1. The original wire image
[0111] There is a lot of noise in the background of the original wire image, such as Picture 9 Shown.
[0112] 2. Image preprocessing
[0113] Image preprocessing removes image noise, and at the same time improves the contrast of the foreground and background areas of the image, such as Picture 10 As shown, it is convenient for subsequent identification.
[0114] 3. Canny edge detection
[0115] Use Canny edge detection algorithm to extract edges in the image, such as Picture 11 As shown, it can be seen that there are a large number of interference line segments in the image, and the edges of the wires can also be completely detected.
[0116] 4. Hough straight line detection
[0117] On the basis of Canny detection, the straight line segment in the image is detected by the Hough line detection algorithm. The detection effect is shown in the figure below. At this time, there are only the edges of the wires in the image.
