Automatic identification method and positioning method based on automatic identification method

Abstract

The invention provides an automatic identification method and a positioning method based on the automatic identification method. The automatic identification method comprises the steps that S10, a target image of a screw cap and position information, size and screw cap type information of the target image are acquired; s20, carrying out angular point extraction on the target image of the screw cap to obtain an initial angular point set; s30, matching the initial angular point set with a preset angular point position template of a corresponding type of screw cap to obtain a final angular point set of the target image; and S40, performing minimum circumcircle fitting on the final angular point set to obtain a center coordinate of a circumcircle. According to the method, the features of the screw caps of different types of screws are identified, so that the position and the type of the screw cap of the target screw are determined, the angular point of the screw cap of the target screw is further identified, the angular point is matched with the preset angular point position template, and finally the center position of the target screw is obtained. And completing identification of the position of the target screw.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an automatic identification method and a positioning method based on the automatic identification method. Background technique [0002] Industrial intelligence is a major trend at present. The demand for labor on the assembly line is huge, and misoperations are prone to occur. Intelligent algorithms are needed to improve the efficiency of industrial production lines. The OSA production of optical communication requires a lot of labor, and the efficiency needs to be improved. [0003] Screw caps are analyzed and positioned from multiple angles in the production and use environment of optical modules; whether the screw caps are properly used plays a very important role in the quality of the entire product. Some positions are 6 corners, and 3 corners are embedded. It is easy to make mistakes and the labor cost is too high. Contents of the invention [0004] In vi...
