Problems solved by technology
However, because the surface of the hydraulic valve block is smooth and easily affected by light, it is difficult to obtain an accurate edge image in the hole, and the burr detection cannot be completed, and the canny edge detection operator is interfered by noise during use, so it is necessary to adjust the double threshold to obtain more accurate The edge detection effect is very good, and the hole is a small part of the entire hydraulic valve block, so when the edge detection in the cavity is performed on the entire hydraulic valve block, refined edge detection is also required

The invention relates to the technical field of artificial intelligence, in particular to a computer image edge detection method. The method collects the image of the hydraulic valve block to obtain the hole image; converts the hole image into a grayscale image, and obtains the value of each pixel according to the grayscale difference and relative position vector between each pixel in the grayscale image and its surrounding pixels. The gray-scale continuous index and the optimal gray-scale connection direction; based on the optimal gray-scale connection direction, the center point of the hole is obtained, and the distance between each pixel and the center point of the hole is obtained, and the strength of each pixel is obtained from the distance and the gray-scale continuous index. Edge possible index; the high and low gray thresholds are obtained from the strong edge possible index, and the edge pixels of holes are confirmed according to the high and low gray thresholds. The high and low gray thresholds are obtained by combining the gray continuity of pixels and the position coordinates adaptively, and the edge pixels are confirmed by the high and low gray thresholds to complete the edge detection of holes more accurately, and the robustness is better.
Description
technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a computer image edge detection method. Background technique [0002] During the production process of the hydraulic valve block, the burr is easy to appear on the edge of the hole, so it needs to be deburred. At present, the canny edge detection operator is usually used to obtain the hole edge image of the hydraulic valve block. However, because the surface of the hydraulic valve block is smooth and easily affected by light, it is difficult to obtain an accurate edge image in the hole, and the burr detection cannot be completed, and the canny edge detection operator is interfered by noise during use, so it is necessary to adjust the double threshold to obtain more accurate The edge detection effect is very good, and the hole is a small part of the entire hydraulic valve block, so when the edge detection in the cavity is performed on the entire hydraulic valve bl...
