Abstract

The invention relates to a point cloud model construction method and device, equipment and a storage medium. The method comprises the steps of obtaining a first feature of a panoramic image in a panoramic image set; determining at least one group of image pairs in the panoramic image set and a corresponding matching result according to the first features, the image pairs comprising two panoramic images matched with the first features, and the matching result indicating a corresponding relation between the first features of the two panoramic images; and constructing a point cloud model according to the at least one group of image pairs and the corresponding matching result. The panoramic images are adopted for matching, and the point cloud model is further constructed according to the matching result, so that the number of the images of the image set can be reduced, the matching efficiency and the modeling efficiency are improved, the range of the space corresponding to the panoramic images is relatively large, the matching effect between the panoramic images can be improved, and the precision and the quality of constructing the point cloud model are improved.

Description

technical field [0001] The present disclosure relates to the technical field of three-dimensional modeling, and in particular to a point cloud model construction method, device, equipment and storage medium. Background technique [0002] With the development of artificial intelligence technology, spatial modeling technology has become richer and more accurate. Motion recovery structure technology can use multiple images to construct a 3D point cloud model, which can be widely used in the fields of physical space digitization, high-precision map construction, and augmented reality. In related technologies, the matching effect between multiple images is not good, which leads to low precision and poor quality of point cloud models constructed sequentially. Contents of the invention [0003] The present disclosure provides a point cloud model construction method, device, equipment and storage medium. [0004] According to a first aspect of an embodiment of the present disclo...
