It is a set of UAV ground surface crack datasets, containing a variety of complex factors in real-world scenes, which verifies the applicability of the proposed method on UAV images and provides important data support for the research on ground surface crack seg mentation.
The diameter of the rivet hole is 5mm. In the experiments at the Cooperative Institute, the AE sensor spacing was set to 130mm, where the centers of sensor 1 and sensor 2 were 90mm from each end of the test piece. The waveform flow data obtained in the experiment only retained the information from 30 minutes before the crack initiation to the fracture of the test piece, and the image data of the test piece during this period were recorded.
