Problems solved by technology

For this step, part of the solution is to use the method of human eye detection, but for the case of a large number of components or small components, this method is prone to errors and omissions, and the efficiency is low
Other existing solutions use the component detection function in the AOI equipment for detection. Compared with the traditional human eye detection, the accuracy of this method is improved, but the cost of AOI equipment is high, and manual inspection is also required during the detection process. Participation, not fully automated

Abstract

The invention discloses a component detection device and method, which collects and inputs images of components, uses feature point matching for the input image to identify target information to obtain the quantity and type of components, and compares the components with the target image information , to determine whether the components under test meet the test requirements, so as to automatically detect whether the components under test are qualified. The invention relies on digital image processing technology to realize image detection without manual participation, and changes traditional subjective visual discrimination into objective image discrimination, which can improve the detection accuracy of components, reduce missed detection rate and labor cost, and improve production and testing efficiency.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a component detection device and method. Background technique [0002] In the field of manufacturing and processing, whether it is in the process of processing or the final inspection process, it is necessary to inspect the quantity and type of components to confirm that there are no leakage and wrong materials after the final product is produced. For this step, part of the solution is to use the method of human eye detection, but for the case of a large number of components or small components, this method is prone to errors and omissions, and the efficiency is low. Other existing solutions use the component detection function in the AOI equipment for detection. Compared with the traditional human eye detection, the accuracy of this method is improved, but the cost of AOI equipment is high, and manual inspection is also required during the detection process. Participatio...
