The present disclosure relates to a method, device, device and storage medium for constructing a point cloud model, including: acquiring a first feature of a panoramic image in a panoramic image set; determining at least one group of images in the panoramic image set according to the first feature A pair and a corresponding matching result, wherein the pair of images includes two panoramic images whose first features are matched, and the matching result indicates a correspondence between the first features of the two panoramic images; according to the at least one set of images Construct a point cloud model for the corresponding matching results. Since the panoramic image is used for matching and the point cloud model is further constructed according to the matching result, the number of images in the image set can be reduced, thereby improving the matching efficiency and modeling efficiency, and the corresponding space of the panoramic image has a large range, so the panoramic image can be improved. The matching effect between images can improve the accuracy and quality of the point cloud model.
Description
technical field [0001] The present disclosure relates to the technical field of three-dimensional modeling, and in particular, to a method, device, device and storage medium for constructing a point cloud model. Background technique [0002] With the development of artificial intelligence technology, the spatial modeling technology has become richer and more accurate. The motion recovery structure technology can construct a 3D point cloud model from multiple images, which can be widely used in the fields of physical space digitization, high-precision map construction, and augmented reality. In the related art, the matching effect between multiple images is not good, which leads to low precision and poor quality of the point cloud models constructed sequentially. SUMMARY OF THE INVENTION [0003] The present disclosure provides a method, apparatus, device and storage medium for constructing a point cloud model. [0004] According to a first aspect of the embodiments of th...
