Underwater Pile Foundation Defect Detection Method Based on Diffusion Probabilistic Model and Improved PointMLP [PDF]

Sensors
To detect damage in underwater pile foundations, we propose a new method based on the diffusion probability model and improved PointMLP. First, PCA-ICP registration is carried out for the point cloud data from different stations using a sonar system.
