Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0061] The printed circuit board classification method provided by this application can be applied in such as figure 1 In the application environment in , the terminal 102 is connected to the server 104 through the network. Specifically, the quality inspector takes pictures of the printed circuit board to be tested through an optical lens such as an industrial camera to obtain an image of the printed circuit board to be tested, and then uploads the image of the printed circuit board to be tested to the terminal 102, and the display of the terminal 102 can be clicked The "...

Abstract

The invention provides a printed circuit board classification method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining an image of a to-be-detected printed circuit board, carrying out mathematical modeling of the image of the to-be-detected printed circuit board, and obtaining a geometric mathematical model of the to-be-detected printed circuit board; when the stock printed circuit board geometric mathematical model of which the similarity with the to-be-tested printed circuit board geometric mathematical model meets a preset threshold value isfound through a similarity algorithm, indicating that the physical circuit board corresponding to the stock printed circuit board geometric mathematical model is the to-be-tested printed circuit board; and obtaining feature file information carrying classification information corresponding to the stock printed circuit board geometric mathematical model to obtain a classification result. In the whole process, number marks and manual classification processing do not need to be added into production materials of the printed circuit boards in a manual mode, the classification efficiency is remarkably improved, the classification accuracy of the printed circuit boards is guaranteed through the image recognition technology, and classification of the printed circuit boards can be efficiently andaccurately achieved.

Description

technical field [0001] The present application relates to the field of image recognition, in particular to a printed circuit board classification method, device, computer equipment and storage medium. Background technique [0002] PCB (Printed Circuit Board, printed circuit board), also known as printed circuit board, is a provider of electrical connections for electronic components. Due to its characteristics, printed circuit boards have become key components of various electronic products. [0003] In order to improve production efficiency, printed circuit board manufacturers will combine many printed circuit board orders with the same technology and quantity from customers into one engineering data for production, and then classify them after the actual printed circuit boards are produced. Specifically, the current classification method of printed circuit boards mainly adds the customer's unique "number mark" on the "solder mask" or "character" layer of the printed circui...
