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.

This application relates to an image detection method, a vertex registration method, and a storage medium. The image detection method includes: acquiring a vertex detection model of a target object; using the vertex detection model to perform local feature detection processing on the image to be detected of the target object, obtaining several vertices on the target object; and outputting several vertices on the target object, each vertex having one or more of the following information: position coordinates, category, bounding rectangle, and enclosing rectangle. In this technical solution, when acquiring the vertex detection model, pre-registration processing is performed on each vertex of the sample images participating in network training, which helps to enhance the image detection performance of the model.

The application discloses a point cloud data registration method and system, electronic equipment and a storage medium, and the method comprises the following steps: acquiring a model point cloud of a three-dimensional model of a scene and a scene point cloud; performing plane feature extraction on the model point cloud and the scene point cloud to obtain a model point cloud plane feature set and a scene point cloud plane feature set respectively; performing line feature extraction on the model point cloud and the scene point cloud according to the two feature sets to obtain a corresponding model point cloud line feature set and a scene point cloud line feature set; performing feature matching on the model point cloud and the scene point cloud based on the model point cloud plane feature set, the scene point cloud plane feature set, the model point cloud line feature set and the scene point cloud line feature set to determine a feature matching relationship; and determining a coordinate transformation relationship of the model point cloud and the scene point cloud based on the feature matching relationship to register the model point cloud and the scene point cloud. Through the above method, the registration between the three-dimensional model and the point cloud can be realized through the plane feature and the line feature, and the registration efficiency is improved.
