Three-dimensional chemical industry park establishing method

Abstract

The invention discloses a three-dimensional chemical industry park establishing method. According to the three-dimensional chemical industry park establishing method, three-dimensional information of a three-dimensional chemical industry park is obtained according to characteristics of a to-be-scanned target object by adopting different types of three-dimensional laser scanners, the contradiction between the scanning precision and the scanning speed is well solved, by utilizing the conversion relationship between the WGS-84 standard coordinate of the target and the coordinates measured by the three-dimensional laser scanners, three-dimensional data obtained by the three-dimensional laser scanners is conveniently converted into the WGS-84 standard coordinate system which is universal to the latest 2,000 coordinate system, so that the obtained data can be directly applied to engineering and management, and the three-dimensional chemical industry park establishing method conforms to the current GIS (geographic information system) technical standard, and has great application value.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional surveying and mapping of buildings, and in particular relates to a method for establishing a three-dimensional chemical industry park. Background technique [0002] With the continuous progress and development of society and economy, more and more cities have established special chemical parks to concentrate various chemical enterprises. The establishment of a chemical park can centrally arrange key chemical enterprises within a certain area, thereby forming a cluster of chemical enterprises, which is conducive to the rational use of resources and the complementarity of advantages among enterprises. [0003] Since most of the enterprises in the chemical industry park are high-risk heavy industrial enterprises such as petroleum, chemical industry and energy, the nature of the enterprises determines that there must be a large number of major hazards in the park. Scientific monitoring and m...

AI Technical Summary

Problems solved by technology

[0007] The three-dimensional laser scanner has greatly improved the shortcomings of traditional measurement methods such as total stations, and is known as the second technological revolution in measurement science. However, due to its high equipment cost and late appearance, it has not yet formed a complete and mature system. Currently, the commonly used technical means generally use ground-measurement 3D laser scanners to acquire 3D data of the entire park / enterprise, and there are problems of varying degrees:

[0008] (1) Compared with the total station, the measurement accuracy is not high

The total station can achieve a distance measurement accuracy of 1mm±1ppm at the highest, while the ground measurement 3D laser scanner can only achieve a distance measurement accuracy of 3mm50m, which cannot meet the fine measurement requirements of key equipment;

[0009] (2) The measurement speed is still slow

Today's chemical industry parks are getting bigger and bigger, usually with an area of ​​tens of square kilometers or even hundreds of square kilometers. It takes a lot of time and energy to perform 3D measurement in such a large area while ensuring accuracy;

[0010] (3) Data splicing is more difficult

Due to the large area of ​​the chemical industry park, it often takes hundreds of scanning stations to complete the data collection of all areas. It is necessary to splicing the data of each station under different coordinate systems, which requires a lot of work and inevitably causes registration errors;

[0011] (4) It is difficult to connect with GIS system

Different from the total station and GPS, the 3D laser scanner uses its own coordinate system. It is difficult to convert the final data results into the national 2000 geodetic coordinate system. Generally, it can only be done manually, which affects the accuracy of the data. sex
