Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional scene construction, and more specifically, to a three-dimensional scene construction and implementation system based on a Web terminal. Background Art

[0002] With the continuous development of Web technology, Web 3D technology has become an important direction of current Web development. Three-dimensional scene construction uses 3D modeling software to accurately control the size, shape and position of objects to ensure the accuracy of the design. It is widely used in game development, architectural design, cultural heritage protection, virtual reality, robot navigation, medical image processing and other fields. Therefore, the development of a simple and easy-to-use Web-based three-dimensional scene construction and implementation system has important practical significance and application value.

[0003] The existing 3D scene construction and implementation system includes: data acquisition module, 3D reconstruction module, virtual scene modeling module, user interaction and control module, wherein the data acquisition module will use lidar, digital camera, drone and other tools to collect data of actual scene and pre-process the collected data, including denoising, alignment and registration steps, to improve the accuracy and efficiency of subsequent processing; the 3D reconstruction module will use computer graphics and image processing technology to automatically construct a preliminary model of the 3D scene for the processed data; this module can process large-scale data and generate high-precision 3D models; the virtual scene modeling module will perform geometric modeling and texture mapping on the 3D reconstruction results to form a virtual scene; geometric modeling will perform model reconstruction through point cloud or mesh data, and texture mapping will apply real-world images to virtual models to increase the sense of reality; the user interaction and control module provides an intuitive and easy-to-use user interface, supports users to edit and view 3D scenes and realizes interaction between users and virtual scenes.

[0004] However, it still has some shortcomings in actual use, such as high learning cost. The existing 3D scene construction and implementation system 3D scene construction system mostly relies on professional 3D modeling software, which is complicated to operate and has high learning cost; there is little interaction, and after the 3D modeling output, it is impossible to customize and optimize it according to user needs; the accuracy is low.
