Board card material inspection method based on image identification detection

Abstract

The invention relates to a board card material inspection method based on image identification detection. The method comprises the following steps that: 1) adopting a standard board card according to the board card specification and feeding requirements, the consistency with the standard board card needs to be verified during the material feeding, the standard board adoption is obtained through multi-time artificial observation, and the standard board card is used as the subsequent comparison standard; 2) images of the standard board card are collected into a system, in addition, the pixel color information is extracted and is converted into a pixel information table represented by numbers, and the table is used as a standard reference table to be used as the comparison reference object; and 3) images of the inspected board cards in the same type are collected into the system, the pixel color information is extracted and is converted into a pixel information table represented by the numbers, the table is compared with the standard reference table, the result shows that the position of the board card to be compared is a doubtful point position when the number of unmatched pixel color information is greater than the image comparison sensitivity value sigma in the same position regions, and the unmatched position prompt of the corresponding board card is given.

Description

technical field [0001] The invention relates to the field of computer communication. Specifically, a board material inspection method based on image recognition and detection is used to solve the current problem of high labor intensity and low efficiency in the inspection of board materials, and greatly improves the inspection of materials. accuracy and improve inspection efficiency. Background technique [0002] With the continuous improvement of customers' requirements for product quality, higher requirements are put forward for the inspection of today's server products, especially after PCBA, the inspection of board card storage needs to invest a lot of manpower and material resources to strengthen product inspection ;In the design of the board, there are many materials that do not need to be placed on the board during PCBA. These materials are either used for function selection, reserved for function upgrade, or reserved for cost reduction, etc. Etc. For such materials,...
