Abstract: Edge detection is a key link in image processing, such as visual positioning, part defect identification and visual measurement, and its detection quality directly affects the accuracy of subsequent image target identification and positioning. Aiming at the problem of selecting the appropriate edge detection algorithms for specific image processing applications, based on the improved image reconstruction method, an image edge detection quality evaluation algorithm based on multi-directional sliding window linear interpolation reconstruction method was proposed. Firstly, using the maximum continuous non-edge rectangular region of the edge image to be processed as the reconstruction search window, a linear interpolation image reconstruction method with multi-directional sliding window was designed. Then, based on the characteristics of image edges, an optimal evaluation method for edge detection algorithms was established, which integrates image structural similarity and edge error detection rate as performance indicators. Finally, the examples were applied to verify the performance of the reconstruction algorithm and the feasibility and correctness of the optimization method through experiments. The results show that the accuracy of the edge image reconstruction algorithm is the highest. In the experiment, the structural similarity of the reconstructed image can reach 0.708 7, and the time consuming is 320.902 1 s. Using the proposed optimization method can quickly screen out the best edge processing algorithm, and the evaluation result is consistent with the human visual evaluation, which is convenient to realize the intelligent optimization of the edge detection algorithm and the intelligent image processing.
