Problems solved by technology

The three-dimensional display technology in the prior art only simulates terrain features such as mountains through digital elevation models, which can only simulate the trend characteristics of the line in the terrain, and cannot reproduce the features of the ground
In addition, the application of the 3D model in the existing technology generally only supports the line inspection function of flying along the line, the viewing angle and flight path can only be determined according to the current line, the simulated human eye position can only be in the direction of the line, and the viewing angle is limited to the line around, it is impossible to artificially determine the flight direction and flight position, the overall environment is not well grasped, and the three-dimensional space roaming cannot be freely performed, resulting in restrictions on the selection of power lines

Abstract

The invention relates to a method and device for roaming establishment in stereoscopic scenes of a three-dimensional optimization and line selection system and a three-dimensional optimization and line selection system. The method comprises the steps of: establishing a relief model according to three-dimensional coordinates of regular net points on a digital elevation model file; establishing a three-dimensional model of a tower according to three-dimensional coordinates of each point on the tower in a tower diagram, calculating coordinates of each tower point in a three-dimensional scene of the relief model according to an angle of rotation of the position of the tower, and drawing coordinate points of the tower in the three-dimensional scene of the relief model; reestablishing the stereoscopic vision of a dimensional scene in a three-dimensional scene by a left and a right stereopairs on the basis of the artificial stereoscopic vision principle, and subjecting the three-dimensional scene to a three-dimensional roaming. By adopting the method, the overall environment can be controlled according to the artificial stereoscopic vision principle in the roaming of the three-dimensional scene, the free roaming in multiple angles and multiple depths of field is achieved, and the viewing of the three-dimensional scene at any angle is supported, thereby a great support is provided for the optimization and line selection of power.

Description

technical field [0001] The invention relates to a roaming method for creating a three-dimensional scene for a three-dimensional optimized line selection system, a roaming device for creating a three-dimensional scene for a three-dimensional optimized line selection system, and a three-dimensional optimized line selection system. Background technique [0002] The application of the existing three-dimensional display technology in power line selection is only a simple simulation of three-dimensional terrain. The three-dimensional display technology in the prior art only simulates terrain features such as mountains through digital elevation models, which can only simulate the direction characteristics of the line in the terrain, and cannot reproduce the characteristics of ground objects. In addition, the application of the 3D model in the existing technology generally only supports the line inspection function of flying along the line, the viewing angle and flight path can only...
