This invention relates to the field of
computer vision technology, specifically to a
point cloud registration method,
system, storage medium, and apparatus based on a
diffusion model. The method includes: acquiring training samples, including source point clouds and target point clouds; using a
point cloud feature extraction module to extract features from the source and target point clouds respectively, obtaining features 1 and 2; using a feature interaction module to fuse features 1 and 2, obtaining features F1 and F2; using a
point cloud generation module to generate two aligned point clouds, Ag and Bg; using a
transformation matrix prediction module to calculate the correspondence between the original point cloud and the generated point cloud Ag, and between the original point cloud and the generated point cloud Bg, obtaining the predicted
transformation matrix and translation vector; calculating the model's
loss function, adjusting the
model parameters, and completing model training when the
loss function converges. This invention, based on a
diffusion model, transforms the registration problem into a generation problem, improving the accuracy of point cloud registration.
