Stock yard contour line digitization method and system

Abstract

The invention discloses a stock yard contour line digitization method and system, and belongs to the technical field of data processing. The method comprises the following steps: acquiring three-dimensional point cloud data of a stock ground; generating a blank point cloud template according to the boundary of the stock yard; after dimensionality reduction of the three-dimensional point cloud data, drawing the dimensionality-reduced data on the blank point cloud template to generate a data point cloud template; judging whether a blank area exists on the data point cloud template or not, repairing the blank area, and then smoothing the data point cloud template by adopting a fuzzy method; after repairing is completed, generating a contour line pool graph according to the data point cloud template; and converting the color of the data point cloud template, covering the contour line bool graph on the data point cloud template after color conversion, and adding external data for describingstock yard information to the data point cloud template to generate a contour line two-dimensional stock yard graph. According to the method, a complex three-dimensional model is converted into a simple two-dimensional model in a dimension reduction mode, and an operator can operate the method easily, conveniently and visually.

Description

technical field [0001] The invention relates to a method and system for digitizing stockyard contour lines, and belongs to the technical field of data processing. Background technique [0002] In the current era, the heavy industry is vigorously developing the digital industry. The 3D data collected by scanners, GPS, UWB and other means are used in industrial operations and industrial management, providing operators with clear and safe operation planning, and also for management. provide accurate management data. The use of 3D data has problems such as multiple viewing angles and operating depth. In the actual operation and production process, not only does the operator have certain 3D operating technology requirements, but also because of the viewing angle problem, it will also lead to the selection of the depth of the on-site operation area. Misoperation or selection of the wrong area caused by abnormalities. For this reason, each selection requires multiple perspectives ...

AI Technical Summary

Problems solved by technology

The use of 3D data has problems such as multiple viewing angles and operating depth. In the actual operation and production process, not only does the operator have certain 3D operating technology requirements, but also the problem of viewing angle will also lead to the selection of depth in the field operation area. Misoperation or selection of the wrong area caused by abnormality, for which each selection requires multiple perspectives to confirm the actual situation on site

And the original information carried by each point is too single

The coupling between points is strong, and a single point modification after the model is composed will affect the positional relationship description of all three points

And when adding data of other dimensions, the display is complicated and requires high requirements for operators
