Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0040] The invention provides a metal plate defect detection and measurement method based on deep learning, the method comprising the following steps:
[0041] 1) Establish and train a multi-cascade defect detector based on deep learning target detection;
[0042] 2) using the multi-cascade defect detector to detect metal plate defects;
[0043] 3) When a defect is detected, the physical size of the defect is measured by a checkerboard calibration method.
[0044] The present invention adopts cascade detectors of multiple deep learning target detection algorithms, and the target det...
