Problems solved by technology

[0002] At present, most of the processing of point cloud files is carried out manually, and the data is not processed before drawing the point cloud. Rotation, translation and other operations are required for fitting.
And the versatility of reading point cloud files is poor, only the specified storage format can be read, and point cloud files without specified separators cannot be read

Abstract

The invention discloses a system for rapidly reading a point cloud document. The system is used for establishing N threads with multiple task processing ability; the point cloud document is divided into N segments of point cloud documents, and the N segments of point cloud documents are rapidly read in parallel and are respectively stored into N arrays; coordinate values of an X axis, a Y axis, a Z axis corresponding to each point in each segment of point cloud document are intercepted; coordinate axes are mutually transformed according to the selection of users for the coordinate axes; the coordinate values corresponding to the coordinate axes are replaced with the set values according to user set; all the arrays of the N threads are combined into a coordinate array; and a point cloud picture is drawn according to the coordinate values of the X axis, the Y axis and the Z axis of each point in the coordinate array. The invention also provides a method for rapidly reading the point cloud document. With the adoption of the method and the system for rapidly reading the point cloud document, the generality of reading the point cloud document can be improved; and the cloud data is processed before the point cloud picture is drawn.

Description

technical field [0001] The invention relates to a file reading method and system, in particular to a point cloud file fast reading method and system. Background technique [0002] At present, most of the processing of point cloud files is carried out manually, and the data is not processed before drawing the point cloud, and operations such as rotation and translation are required during fitting. Moreover, the versatility of reading point cloud files is poor, and only specified storage formats can be read, and point cloud files without specified separators cannot be read. Contents of the invention [0003] In view of the above, it is necessary to provide a method for quickly reading point cloud files, which can improve the versatility of point cloud file reading, and process point cloud data before drawing point cloud pictures. [0004] In view of the above, it is also necessary to provide a fast reading system for point cloud files, which can improve the versatility of p...
