Abstract
Aiming at detecting cracks in photovoltaic images, a crack detection algorithm of photovoltaic images based on Laplacian pyramid decomposition is studied in this paper. Firstly, in order to suppress noise from the crack area, the image is subjected to a filtering process and contrast enhancement operation. Then, the multi-scale edge detection based on Laplacian pyramid decomposition is applied to the processed image to extract the edge of the image. The results of the extracted fractures are optimized to eliminate the influence of partial noise. Through tests and comparisons, the algorithm is proved effective on crack detection for photovoltaic image.
