Converting the electric energy meter image into a gray image;

And then the Sobel operator is applied to the horizontal and vertical directions of the image to calculate gradients, the edge direction and intensity in the image are determined, the local maximum gradient value in the gradient direction is kept through non-maximum value inhibition so as to refine the edge, the strong and weak edges are distinguished through setting a high and low threshold value, the real edge points are screened out, only the weak edge points connected with the strong edge are kept, so that false detection caused by noise or color change is avoided, finally, the characteristics of the electric energy meter are extracted according to the result of edge detection, accurate edge information is provided for subsequent identification and analysis work, and clear edge characteristics can be effectively extracted from the electric energy meter image through a Canny edge detection algorithm.

using the high threshold to process the image, identifying a strong edge, wherein the strong edge is the most obvious edge in the image, and pixels with gradient values higher than the high threshold are regarded as the strong edge (the strong edge generally represents key structural information in the image, such as frames, pointers and the like of the electric energy meter);
Weak edges are marked using a low thresholded image. The gradient value of the weak edge is between the high and low thresholds (the weak edge may not be as pronounced but is still important information in some cases).
Determining which weak edges should remain by the relationship of the weak edges to the strong edges;
If a weak edge pixel is connected to any strong edge pixel, it is left; if one weak edge pixel is not connected with any strong edge pixel, the weak edge pixel is removed;
And combining the strong edge and the weak edge screened by the method to generate a final edge image.
The explanation of the reservation is as follows: preserving one pixel point means that in the final edge detection result of the image, this point is marked as part of the edge. In the Canny algorithm, strong edge points (whose gradient values are higher than a high threshold) are always preserved. At the same time, those weak edge points (gradient values between high and low thresholds) are also preserved if connected to strong edge points.
The explanation of the removal is as follows:
When a pixel is removed, it is meant that in the final edge detection result of the image, this pixel is not marked as part of the edge.
In the Canny edge detection algorithm, if a pixel point is determined to be non-edge (e.g., its gradient value is below a low threshold, or it is a weak edge point but not connected to any strong edge point), then this point is removed, i.e., not displayed in the final edge image.
