Abstract

The invention discloses a three-dimensional point cloud visualization method and device based on a network. The method comprises the steps that point cloud data in different formats from a scanning device is acquired and processed, and the processed point cloud data is stored in a database; network data exchanging is carried out on the point cloud data in the database based on the Ajax technology and the Webservice technology, and the exchanged point cloud data is transmitted to a browser; by combining the WebGL technology and the HTML5 technology, a three-dimensional scene is established for the point cloud data transmitted to the browser, and visualization is carried out. By means of the method and device, smooth interaction three-dimensional visualization experience in the browser can be provided for online users, and database integration is carried out for the multiple point cloud data formats. In addition, it is not required to download any plugin when network visualization is carried out, and the three-dimensional displaying speed is guaranteed.

Description

Technical field [0001] The present invention relates to the field of three-dimensional visualization, in particular to a method and device for network-based three-dimensional point cloud visualization. Background technique [0002] As a new type of measurement method, 3D laser scanning technology makes it possible to quickly and massively obtain spatial point information. With its non-contact, rapid and continuous acquisition of target information, it has quickly become an important part of obtaining 3D spatial information today. The method is widely used in protection of ancient buildings, monitoring of deformation of extremely large heterogeneous structures, and urban surveying. The scanned point cloud data to be processed is the basis for subsequent data analysis, grid model generation, and three-dimensional visualization. Therefore, seeking a remote, well-interacted network point cloud visualization tool is of great significance for quickly acquiring and evaluating the quali...
