Problems solved by technology

[0003] With the development of UAV technology, GPS technology, and camera technology, oblique photography technology has gradually made great progress in the fields of national defense, surveying and mapping, and has gradually reached a state of acceptable cost under the promotion of commercialization. The landscape planning and design industry has not yet had a good application. According to the relevant needs of landscape design, an efficient and reasonable application method for oblique photography results will play an important role in the future planning and design process.

Embodiment

[0020] Embodiment: a kind of method for landscape ecological status analysis and quantitative planning and design, specifically comprises the following steps:

[0021] S1: According to the red line range delineated by the landscape design, place the red line on the electronic map through coordinate conversion and projection, and preliminarily delineate the flight range of oblique photography based on this. The flight range defines the flight route of the UAV, conducts UAV flight photography, sets ground RTK calibration points and checkpoints, and processes the RTK calibration point data and UAV shooting equipment for internal data processing to obtain a preliminary on-site orthographic plan And the preliminary on-site digital model, based on the "supervised classification" interpretation technology to interpret and classify the orthographic plan, and obtain the classification map of various elements based on the plan image.

[0022] S2: According to the delineated scope, analy...

Abstract

The invention discloses a method for realizing the landscape ecology current situation condition analysis and the quantitative planning design based on the combination of the oblique photography, thenetwork big data and the GPS photographing. The method mainly aims at the problem that a traditional satellite surface elevation DEM cannot meet the refined landscape design requirements. By the aid of the advantages of low cost, high speed, low risk, high precision and the like of an oblique photogrammetry model, the current ecological condition can be effectively obtained through the reasonabledata processing and the multi-software matching according to the design method, a targeted landscape ecological planning and design strategy is provided, and the high-precision quantization results can be quickly obtained.

Description

technical field [0001] The invention belongs to the technical field of 3D landscape planning, and in particular relates to a method for realizing the analysis of current landscape ecological conditions and quantitative planning and design based on oblique photography, network big data, and GPS photography. Background technique [0002] Under the background of the national advocacy of park cities, the scale of landscape planning and design has gradually become huge, which is far beyond the scope of human control. It increasingly needs an accurate and intuitive full information model of the current situation as an aid. Among them, the current ecological conditions are very need. [0003] With the development of UAV technology, GPS technology, and camera technology, oblique photography technology has gradually made great progress in the fields of national defense, surveying and mapping, and has gradually reached a state of acceptable cost under the promotion of commercializatio...
