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...

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The method for establishing a three-dimensional chemical industry park in this embodiment includes the following steps:

[0042] S1. Arrange total station targets (control points) in the chemical industry park:

[0043]Place targets or prisms on the inner surface of the building to be tested, internal equipment, and pipelines. Let the number of targets installed be n. In order to ensure a certain measurement accuracy and facilitate coordinate conversion, the number of targets installed should meet When the 3D laser scanner scans, there are no less than 5 control points within the scanning range of each station;
