Abstract

The invention discloses a solar cell panel crack detection method comprising collecting a solar cell panel image; dividing the solar cell panel image into a plurality of singlechips by horizontal vertical projection, and according to the horizontal projection of singlechip broken gates, cutting the singlechips into multiple blocks; based on Laplacian Pyramid, decomposing the blocks, and using canny algorithm for edge detection of the decomposed blocks to obtain the characteristics of a solar cell panel crack; performing denoising processing on the characteristics of the solar cell panel crack;determining the position of the solar cell panel crack based on the denoised characteristics of the solar cell panel crack. The result of the edge detection based on the Laplacian pyramid algorithm is more complete and smooth, influence of partial noises can be effectively removed, and the accuracy of detection is improved.

Description

technical field [0001] The invention relates to the technical field of crack detection, in particular to a crack detection method of a solar cell panel. Background technique [0002] With the rapid development of the photovoltaic industry, the quality of solar cells has become more and more important. Good quality solar cells not only have good stability, long service life and high photoelectric conversion efficiency. The detection of surface defects of solar cells is a very important link. [0003] The accuracy of current solar crack detection methods is low. Contents of the invention [0004] The invention provides a method for detecting cracks in a solar panel to overcome the above technical problems. [0005] The solar cell panel crack detection method of the present invention comprises: [0006] Capture solar panel images; [0007] Using horizontal and vertical projection to divide the solar panel image into a plurality of monoliths, and dividing the monolith into...
