1. A spot-checking method for a visual inspection system, comprising:
obtaining a plurality of to-be-inspected images;
inspecting the plurality of to-be-inspected images to obtain defect types and/or parameters of a target object in the plurality of to-be-inspected images, comprising:
determining a size of the target object in each of the plurality of to-be-inspected images by calculating a number of pixels included in the target object in the each of the plurality of to-be-inspected images; and
confirming availability of the visual inspection system based on the defect types and/or the parameters, comprising:
confirming the availability of the visual inspection system by comparing the number of pixels included in the target object in each of the plurality of to-be-inspected images with a threshold.
