The invention provides a method, a device, equipment for generating a building model based on an oblique photographical technology and a computer-readable storage medium. The method of the embodiment comprises the steps of generating integrated point cloud data and profile data of a specified building according to a multi-view oblique image; and acquiring monomer point cloud data of the specified building according to the integrated point cloud data by use of the profile data so that three-dimensional reconstruction processing can be performed according to the monomer point cloud data to obtain a monomer model of the specified building. Because the profile data of the specified building are combined with the integrated point cloud data, the monomer point cloud data of the specified building can be precisely extracted, the monomer model of the specified building is further constructed and thus the reliability of the monomer building operation is improved.
Description
【Technical field】 [0001] The present invention relates to image processing technology, in particular to a method, device, equipment and computer-readable storage medium for generating a building model based on oblique photography technology. 【Background technique】 [0002] An oblique image refers to an image captured by an aerial camera at a certain oblique angle, and can also be called a multi-view oblique image. Oblique photography technology is a high-tech developed in the field of international surveying, mapping and remote sensing in recent years. By carrying multiple sensors on the same flight platform and collecting images from different angles such as vertical and oblique, more complete and accurate information on ground objects can be obtained. At present, the model constructed based on multi-view oblique images is an integrated 3D scene model, which is mainly composed of continuous irregular triangulated network (TIN). [0003] However, in the management and appli...
