Three-dimensional model construction method suitable for VR/AR transformer substation operation environment

Abstract

The invention discloses a three-dimensional model construction method suitable for a VR / AR transformer substation operation environment. The method comprises the following steps: S1, quickly collecting a three-dimensional model of a large scene and various drawing data of lines, surfaces and bodies by recording three-dimensional coordinates, reflectivity and texture information of a large number of dense points on the surface of a measured object by utilizing a laser ranging principle; S2, acquiring original image data by using the single lens reflex after effect detection, and rapidly restoring real scenes and models of equipment, towers and lines by using laser point cloud processing software and photogrammetry software; S3, simplifying triangulation network data, reducing the number ofmodel surfaces, achieving the purpose of optimizing the model, adjusting the positions of nodes on the basis of a local-global thought without changing the interconnection mode of the nodes, and improving the uniformity of the image grids on the whole. According to the invention, the problems of long 3D modeling time consumption and poor fineness in the prior art of substation equipment are solved, and a substation operation system is enabled to maintain safe and efficient operation.

Description

technical field [0001] The invention relates to the technical field of substation operating environment, in particular to a method for building a three-dimensional model of a substation operating environment suitable for VR / AR. Background technique [0002] There is a lack of standardized and standardized auxiliary guidance when using maintenance procedures and instructions for power equipment maintenance, troubleshooting, emergency repairs, etc.; there is a lack of visual descriptions, The control tools and means of precise presentation and scenario-based preview, and the necessary warnings and reminders are even more blank, which has brought constraints to production work, mainly in the following three points: [0003] (1) The layout of power equipment is compact, the structure is complex, and the quantity is large, which brings difficult maintenance, complicated inspection and operation, and heavy tasks. Timely, accurate, and efficient maintenance has become an obstacle t...

Problems solved by technology

[0003] (1) The layout of power equipment is compact, the structure is complex, and the quantity is large, which brings difficult maintenance, complicated inspection and operation, and heavy tasks. Timely, accurate and efficient maintenance has become an obstacle to on-site management and control

[0004] (2) The informatization and standardization requirements of equipment maintenance technology are getting higher and higher, and it is difficult to realize the display of equipment attribute information, query of maintenance test process data, and 100% traceability of maintenance quality in paper instructions

[0005] (3) Troubleshooting of different types of equipment is mainly based on operating experience, human factors are greatly affected, and there is a lack of systematic guidance for fault finding, analysis, and judgment and a "one equipment, one book" operation inspection strategy

Usually, due to the characteristics of the power industry, the real operating environment has a high risk factor. Generally, experienced masters use the method of bringing apprentices to pass on experience, which is very inefficient. PPT and pictures are usually used for teaching in the teaching process, which cannot be realistic. The restoration of the entire maintenance process, the students' hands-on ability is also very limited
