Three-dimensional large scene-based transmission line path optimization line selection

Abstract

The invention discloses three-dimensional large scene-based transmission line path optimization line selection. According to the three-dimensional large scene-based transmission line path optimizationline selection, a digital elevation model DEM and a digital orthophoto image DOM are required. The three-dimensional large scene-based transmission line path optimization line selection comprises thefollowing steps of: obtaining the digital elevation model DEM; generating a digital orthophoto image DOM result; respectively reading the digital elevation model DEM and the digital orthophoto imageDOM into the calculated memory space through an algorithm; respectively projecting the digital orthophoto image DOM onto the left and right three-dimensional images according to data of the digital elevation model DEM, so as to display a three-dimensional effect consistent with the practical world to observers, and carrying out transmission line optimal design work on the basis. According to the three-dimensional large scene-based transmission line path optimization line selection, the number of model switching during line optimization is optimized, the field of view for line selection and designer observation is enlarged, the transmission line optimization work is more accurate, the working progress and operation efficiency are improved, the project period is decreased, the risk of laterwire rerouting is reduced, the manpower and material resources are saved and the project cost is saved.

Description

technical field [0001] The invention relates to the technical field of route selection for power transmission lines, in particular to an optimal route selection for power transmission lines based on a three-dimensional large scene. Background technique [0002] With the application of digital remote sensing technology more and more widely in various electric power design institutes, the level of science and technology and management of each electric power design institute is getting higher and higher, and the full digital aerial survey technology has been fully applied in the surveying majors of major electric power design institutes. However, in recent years, major electric power design institutes have found that the traditional photogrammetry software with topographic map collection as the main purpose can no longer adapt to the entire power design process in various levels of overhead power transmission lines, nuclear power plants, large power plants, and substation projec...

Problems solved by technology

This method of using stereo image pairs to optimize the design of transmission line paths requires repeated search for and switching of stereo image pairs that the initial path passes through, which causes great inconvenience to line selectors and designers, and seriously affects The speed of line path optimization will have a certain impact on the construction period of the project; at the same time, this method is not conducive to grasping the direction of the line as a whole, which may lead to unreasonable path optimization, resulting in later rerouting, and affecting the progress of the project
