The invention discloses an AOI equipment fast light intensity curve correction method, system and AOI equipment, and relates to the technical field of AOI equipment light intensity curve correction. The method includes the following steps: synchronously establishing light intensity curves of all individual optical heads of the AOI equipment until the establishment of light intensity curves of all light sources of all individual optical heads is completed; using the established light intensity curves to set all individual optical heads of the AOI equipment to is the current value corresponding to the gray value of the target image, so as to ensure that the image gray values of all single optical heads remain consistent when imaging on the same detection sample. The system includes: a light intensity curve establishment module and a light intensity curve correction module. The advantages of the present invention are: by synchronously establishing the light intensity curves of all the single optical heads of the AOI equipment, compared with the traditional method of establishing light intensity curves one by one for each optical head and one by one light source module, the light intensity curve of the AOI equipment is greatly improved build efficiency.
Description
technical field [0001] The invention relates to the technical field of light intensity curve correction of AOI equipment, in particular to a fast light intensity curve correction method and system for AOI equipment and AOI equipment. Background technique [0002] AOI (Auto Optical Inspection) equipment (automatic optical inspection equipment) usually needs to use multiple sets of optical heads for inspection. Even if the lighting and imaging modules of different optical heads use the same specifications of devices, these devices respond to the input of the same physical quantity, There are always slight differences in the output physical quantities. For example, when the lighting devices of different optical heads input the same current, the output light intensity of the lighting source will still be different; the gray scale of the images captured by different imaging cameras under the same lighting conditions will still be different. This difference between devices leads ...
