[0065] figure 1 This is the flow chart of the method for analyzing and reconstructing information entropy multiplicative fuzzy defect feature based on infrared thermal imaging of the present invention.
[0066] In this embodiment, as figure 1 As shown, a defect reconstruction and feature extraction method based on infrared thermal imaging of the present invention mainly includes three steps: S1, preprocessing of the video stream to be detected; S2, defect reconstruction; S3, feature extraction of the reconstructed image;
[0067] Below we combine the above three steps to describe in detail.
[0068] S1. Preprocessing of the video stream to be detected
[0069] S1.1, the video stream to be detected is represented as a matrix block as: Among them, N I ×N J represents spatial information, N T Indicates time information;
[0070] S1.2. Convert the matrix block into a two-dimensional matrix Y through the vector operator Vec();
[0071] Y=[Vec(Y(1)),Vec(Y(2)),…,Vec(Y(N T )...
