Abstract

The invention aims at providing an image recognition method. According to the image recognition method, welding spots for welding silver wire on the surface of a silver foil in an acquired image are recognized. The acquired image comprises at least one first region corresponding to the silver foil and at least one second region corresponding to the silver wire. The image recognition method comprises the following steps of acquiring the gray?value of each pixel in the first region and the second region, acquiring characteristic points of the first region according to the gray?value of each pixel in the first region, and seeking the welding points in the second region according to the gray?value of each pixel in the second region and the characteristic points. In comparison with the prior art, recognition is carried out according to the gray difference between the silver foil and the silver wire, the position of the silver wire is sought around mass points of the silver foil, the welding spots are finally determined, and the positions of the welding spots are then conveniently, quickly and automatically recognized.

Description

[0001] technical field [0002] The invention relates to the field of image recognition, in particular to a visual image processing method for realizing automatic welding of solar cell arrays. Background technique [0003] The parts of the solar cell array used in domestic space are basically welded by manual welding. The manual positioning method is used to weld the silver wire on the silver foil on the back of the solar wing sail by resistance spot welding. mechanism, each solder joint needs to repeat the process of coarse adjustment, aiming, fine adjustment, trial pressing and then fine adjustment in order to accurately move to the top of the solder joint. [0004] This method is time-consuming and inefficient. It takes about 2 minutes to complete the soldering of a solder spot on a piece of silver foil, which greatly affects the production schedule. At the same time, due to the large number of wires and components on the surface of the solar cell array, manual weldin...
