Abstract
A system for cutting point cloud automatically includes an application server (1), client computers (3), and a database (5). The application server includes: a point cloud inputting module (10) for obtaining point cloud data and constructing an electronic figure according to the point cloud data; a figure changing module (11) for changing positions or views of the figure in the three-dimensional space; a point cloud cutting module (12) for cutting the point cloud automatically by executing a preestablished program; and a storing module (13) for storing the preestablished program and the point cloud after having been cut. A related method is also disclosed.
Claims8
A system for cutting a point cloud automatically, the system comprising an application server, the application server comprising:
- a point cloud inputting module for obtaining a point cloud;
- a point cloud cutting module for cutting the point cloud automatically by executing a preestablished program, the point cloud cutting module comprising:
- a normal function sub-module for delimiting the point cloud area with a polygon, and for choosing to keep which parts of the polygon;
- and
- a mesh point cloud sub-module for generating extra points along the edge of the polygon, and for choosing to cut only a visible patch of the point cloud;
- and
- a storing module for storing the preestablished program and the point cloud after the point cloud has been cut.
A method for cutting a point cloud automatically, comprising the steps of:
- obtaining point cloud data from a database;
- constructing an electronic figure according to the point cloud data;
- determining whether to cut the point cloud automatically;
- determining whether a preestablished program for cutting such kind of point cloud exists in a storing module if the point cloud needs to be cut automatically;
- invoking the preestablished program to cut the point cloud automatically if such preestablished program exists;
- and
- storing the cut point cloud.
A method for perfecting point cloud data automatically, comprising the steps of:
- retrieving said point cloud data;
- constructing a viewable figure formed according to said point cloud data;
- determining whether to cut said point cloud data automatically;
- initiating an available program for said perfecting of said point cloud data when said point cloud data need to be cut automatically;
- automatically removing identifiably undesired parts of said point cloud data therefrom for said perfecting;
- and
- saving said perfected point cloud data.
