Embodiment 1
[0058] In the field of machine vision, when the SSD algorithm is currently used for inspection, a lens module is regarded as one or more detection points for detection, and it is impossible to accurately detect the various positions on the outer surface of the lens module. Therefore, those skilled in the art in the study of lens module damage identification algorithm, have automatically filtered the SSD algorithm, in turn to study how to reduce the cost of those can accurately identify small size target algorithm model. But the progress of such technical ideas is not particularly ideal.
[0059] The applicant jumped out of such a technical idea, the SSD algorithm model that those skilled in the art default to can not detect small size targets is improved, by improving the size of the input picture on the backbone network of the original SSD algorithm model, improving the size of the input picture on the backbone network of the original SSD algorithm model, optimizing and enlarging the
