Appearance inspection system, calculation model construction method and calculation model building program

摘要

Even if the knowledge and experience of artificial intelligence are scarce, the calculation model for effective appearance inspection using artificial intelligence is easily constructed.Solution: when constructing a computational model used for appearance inspection of a test object from multiple initial calculation modelsSelect one initial calculation model andAn output value is calculated by inputting a set of image data taken from a plurality of directions to a selected initial calculation model.The difference between the teacher data and the output value is small.The weights of each layer of the initial computation model are sequentially changed and learned.If the difference does not converge even if the initial calculation model is repeated a predetermined number of times, theThe layer structure of the initial calculation model is sequentially changed and evolved.Even if an evolutionary initial computation model is learnedIf the difference does not converge below a predetermined threshold, then another initial calculation model is selected.If the difference converges below the threshold,The initial calculation model is then registered as a computational model.Diagram
