Urban engineering planning method and system based on unmanned aerial vehicle remote sensing surveying and mapping

Abstract

The invention relates to an urban engineering planning method based on unmanned aerial vehicle remote sensing surveying and mapping, and belongs to the technical field of urban planning. The method comprises the steps: obtaining initial planning drawing information of urban engineering, and building an initial planning drawing three-dimensional model based on the initial planning drawing information of the urban engineering; obtaining geographical location information of a target area where the current urban planning project is located, and obtaining a combined AR scene graph based on the geographical location information; establishing a secondary planning drawing three-dimensional model based on the combined AR scene graph and the initial planning drawing three-dimensional model; searching an obstacle point from the three-dimensional model of the quadratic programming drawing; and determining a final urban engineering planning scheme according to the obstacle points. During urban planning, the AR scene technology can be directly used, the unmanned aerial vehicle remote sensing surveying and mapping technology is utilized to integrate the lacked scene model into the AR scene, and the calculation amount of a computer system can be reduced by utilizing the technology, so that the calculation efficiency of urban engineering planning is improved.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to an urban engineering planning method and system based on remote sensing mapping of drones. Background technique [0002] With the rapid development of modern surveying and mapping science and technology, the acquisition and processing capabilities of surveying and mapping geographic data have been greatly improved. From satellites, aviation, and low-altitude drones to ground surveying robots and underground geophysical radars, an integrated space-ground information acquisition and processing capability has been formed. . In my country, especially in the past 20 years, the state and various provinces and cities have promoted a series of major surveying and mapping geographic projects, and accumulated massive surveying and mapping geographic data, including multi-source remote sensing image data, basic geospatial data, urban underground pipeline data, and urban underground s...

Problems solved by technology

[0003] In the prior art, in urban planning engineering, such as natural gas pipeline planning engineering, sewer pipeline planning engineering, sidewalk planning engineering, and cable line planning engineering, in the process of engineering planning, the calculation amount of the computer system is too large, and it cannot be obtained quickly. Planning methods; and most urban planning projects require manual field investigation of the actual situation, resulting in low efficiency in the early stage of urban engineering drawings
