Concrete test piece anti-exchange method based on deep learning and image recognition

The invention discloses a concrete test piece anti-exchange method based on deep learning and image recognition, and relates to the technical field of concrete test piece management, and the method comprises the following steps: S1, concrete test piece information collection; s2, data preprocessing; s3, establishing a deep learning model; s4, extracting coordinates of three-dimensional feature points; s5, comparing the consistency of the test pieces; and S6, outputting a discrimination result. According to the concrete test piece anti-exchange method based on deep learning and image recognition, a mobile phone is used for shooting a wet concrete test piece picture, a depth camera is used for shooting a dry concrete test piece picture, deep learning and a three-dimensional feature recognition technology are combined, a deep learning model is constructed, and the concrete test piece anti-exchange method based on deep learning and image recognition is obtained by training the learning model. And establishing a c
