Abstract

The invention relates to the field of artificial intelligence, in particular to a battery plate grid line self-adaptive extraction method and system based on Hough transform. Acquiring a solar cell panel grid line edge image; performing straight line detection by utilizing Hough transform to obtain a plurality of intersection points, and obtaining an accumulated value of the intersection points; a threshold range is set to screen the intersection points for multiple times, and polar coordinates of the intersection points obtained through screening each time are obtained; calculating the angle loss of the threshold value according to the number of polar coordinate angles of different intersection points; calculating the deviation value loss of the threshold according to the polar radius variance of the polar coordinates of the intersection point; calculating the accumulated loss of the threshold value according to the accumulated value of the intersection point; calculating a comprehensive loss index of the threshold value, and taking the threshold value corresponding to the minimum value as an optimal threshold value; and obtaining the number of the grid lines according to the number of the intersection points screened out by the optimal threshold. According to the method, the threshold value of Hough transform is adjusted in a self-adaptive manner, so that the grid lines detected by the solar cell panels of different models have high accuracy, and meanwhile, the detection efficiency of the grid lines is ensured.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method and system for adaptively extracting grid lines of a battery plate based on Hough transform. Background technique [0002] my country is the most energy-demanding country, and the demand for electricity has been growing rapidly. As an important source of clean energy, solar panels have always been an energy project vigorously developed by the country. The power generation principle of silicon cells is to use the photovoltaic effect. A potential difference is formed, and a built-in electric field is established, but there is a voltage, and there is no current path. It is necessary to use wires to export these electricity. The grid wire is the first-level wire that carries the current. ), and then connected to the junction box, and finally exported by the cable of the junction box. [0003] The grid lines of the solar panel have a great influence on its performance, a...
