Problems solved by technology

However, most of the existing self-inspection methods are based on the effect of visually collecting images by professionals on the spot, and then manually correcting each parameter. However, this method also has many problems in actual use, such as large errors in human judgment, poor repeatability and consistency. , thereby reducing the performance of AOI detection equipment

Abstract

The invention discloses a detection device and a visual imaging system self-checking method and self-checking device used for the same. The method comprises steps of acquiring graphical information of multiple end faces of a to-be-detected piece through a visual imaging system; and according to the graphical information, correcting all parameter values of the visual imaging system.

Description

technical field [0001] The present invention relates to a visual imaging system self-inspection method and self-inspection device, in particular to a visual imaging system self-inspection method and self-inspection device for testing equipment. Background technique [0002] With the rapid development of science and technology, the application of AOI detection equipment is also more extensive, and various self-inspection methods of the visual imaging system of AOI detection equipment have been derived, although these self-inspection methods can correct various aspects of the visual imaging system parameters, thereby improving the accuracy of the visual imaging system. However, most of the existing self-inspection methods are based on professional on-site visual inspection of the image collection effect, and then manually correcting each parameter, but this method also has many problems in actual use, such as large errors in human judgment, poor repeatability and consistency ...
