Abstract

The invention provides a three-dimensional model construction method and device and a storage medium, relates to the technical field of three-dimensional models, and is used for solving the technical problem that a three-dimensional model cannot be flexibly constructed. The method comprises the steps that after area position information of a to-be-rendered area under an initial three-dimensional model and video data of a scene corresponding to the initial three-dimensional model are acquired, target texture position information matched with the area position information of the to-be-rendered area can be determined from texture position information of multiple pieces of video frame data included in the video data; and obtaining target texels in the target video frame data from the target video frame data to which the target texture position information belongs, and rendering the target texels into the to-be-rendered region to obtain a target three-dimensional model comprising the video data of the to-be-rendered region. Wherein each piece of video frame data comprises a plurality of pieces of texture position information and a plurality of texels in one-to-one correspondence with the plurality of pieces of texture position information. According to the invention, the flexibility of constructing the three-dimensional model is improved.

Description

technical field [0001] The present application belongs to the technical field of three-dimensional models, and in particular relates to a three-dimensional model construction method, device and storage medium. Background technique [0002] With the improvement of 3D model construction technology, the fusion technology of 3D model and video data has appeared in related technologies. By restoring the video data to the 3D model, this technology can dynamically display the content of the video data in the 3D model. [0003] With the development of related technologies, some users put forward more refined and diversified requirements for dynamically displaying video data in 3D models. For example, the traffic control department hopes to focus on displaying content related to roads in the 3D model, and the airport management department hopes to focus on displaying content related to airways in the 3D model. However, related technologies are difficult to meet the needs of these u...
