Embodiment Construction

[0056] Below in conjunction with specific embodiment the present invention is described in further detail:

[0057] A distributed management method for three-dimensional laser point cloud entity objects, comprising the following steps:

[0058] S1. Construct a spatial octree index based on a single point cloud file data to generate a three-dimensional tile file;

[0059] S2. Based on the point cloud 3D entity encoding rules, manage the spatial attributes, feature attributes and time attributes of the single point cloud;

[0060] S3. Realize graphical interactive operation oriented to point cloud object management;

[0061] S4. Send a management operation response request to the graphical interactive operation to realize the separation of the operation client and the data server;

[0062] S5. Store the underlying data in units of files, perform redundant backup, load balancing and horizontal expansion, and provide external data file access services based on URLs;

[0063] S6. ...

Abstract

The invention discloses a distributed management method and system for a three-dimensional laser point cloud entity object, and belongs to the technical field of mobile measurement big data informatization management. According to the method, the functions of uploading, downloading, storing, searching, inquiring, modifying and the like of the point cloud objects are achieved, spatial octree indexmodeling is conducted on the single point cloud object during uploading, and original data before modeling, octree indexes after modeling and node data of the octree are all stored and retrieved basedon the distributed technology, so the robustness, the expansibility and the access efficiency of data storage are improved; the system realizes search and query functions based on object features, and can realize layered and partitioned display; data already stored in the system is subjected to related operations by using network services based on a BS architecture, and is interacted and displayed by using a graphical interface, so that the technical threshold of a system user is reduced.

Description

technical field [0001] The invention discloses a distributed management method and system for three-dimensional laser point cloud entity objects, belonging to the technical field of mobile measurement big data information management. Background technique [0002] The 3D point cloud model can discretely sample objects in the real world. It has the characteristics of simple data structure and the ability to express arbitrary complex details. It is widely used in reverse engineering, virtual reality, space measurement, cultural relics protection and other fields. The laser point cloud data for mobile measurement has the characteristics of large data volume. The traditional way of managing these data is high in efficiency and low cost, and has certain requirements for the technical ability of managers, which has been unable to meet the development requirements of current mobile measurement laser point cloud technology and applications. . With the development of big data technol...
