Abstract

The invention provides a laser point cloud rendering method and device and is applied in the field of data processing. The method comprises the steps that a standard point cloud file is generated according to point cloud data in all formats in the AutoCAD, wherein a standard point cloud format comprises PCG format point cloud datum, a window range of the AutoCAD and a preset point cloud display threshold. According to the PCG format point cloud datum, the window range of the AutoCAD and the preset point cloud display threshold, a three-dimensional window is counted and points to be rendered displayed in the point cloud are loaded, the points to be rendered acquired in the point cloud are added to the AutoCAD point cloud objects, the point cloud is rendered. Point cloud datum in different formats are transformed into point cloud datum in standard PCG format, the point cloud datum including the standard formats are generated, and the point cloud is rendered, a technical problem that a variety of data formats are compatible is achieved and the production operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a laser point cloud rendering method and device. Background technique [0002] At present, the AutoCAD platform supports the conversion of third-party point cloud format data into the PCG point cloud format supported by itself for loading management and rendering display. AutoCAD supports the conversion of various third-party point cloud data formats: fls, xyz, xyb, txt, asc, LAS, pts, ptg, ptx, clr, cl3, etc. The above data can be converted into PCG point clouds supported by AutoCAD regardless of the amount of data data file. During the process of loading PCG point cloud data, AutoCAD will create an AutoCAD point cloud object and associate it with the corresponding PCG point cloud file, so as to facilitate data management. AutoCAD will bind a unique renderer for each PCG point cloud object, which is used for the point cloud rendering display browsing process in the 3D window. ...
