Abstract

The invention relates to the technical field of artificial intelligence, in particular to a photovoltaic cell panel solder strip offset detection method and device based on artificial intelligence. The method comprises the steps: acquiring a front view of the surface of a photovoltaic cell panel, and cutting the front view to obtain and number a cut graph of each solder strip; carrying out edge detection on the cut image of the solder strip, and sampling an edge binary image to obtain coordinate information of sampling points; performing linear fitting on the sampling points to obtain a linearequation; carrying out polynomial fitting on the sampling points, setting an error function to evaluate and optimize the coefficient of the polynomial, establishing a fitting degree evaluation indexto determine the highest power of the best fitting degree, and obtaining a polynomial equation reflecting the actual trend of the edge of the solder strip; and determining whether the solder strip deviates or not through difference operation of the polynomial equation and the linear equation to obtain position information of the deviated solder strip. According to the method, the problems that thecurrent solder strip offset depends on manual detection, the efficiency is low and the assembly power is attenuated can be improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based method and device for detecting the offset of welding strips of photovoltaic cell panels. Background technique [0002] Photovoltaic welding strips are tinned copper strips, sub-converging strips and interconnecting strips, which are used in the connection between photovoltaic module cells and play an important role in conducting electricity and collecting electricity. Therefore, the quality requirements of photovoltaic panels for welding strips are getting higher and higher. . [0003] In the production process of photovoltaic panels, uncontrollable factors such as welding process fluctuations and electrode oxidation will cause various defects in photovoltaic panels, and ribbon offset is one of them. Ribbon offset will affect the normal flow of current and cause component power attenuation. The existing ribbon inspection...
