Problems solved by technology

[0005] The workload is huge: if it is necessary to generate a real vegetation layout, it can only be done manually at present
However, the number of plants in urban scenes is huge, and for the work of plant placement, the artificial efficiency is extremely low

Embodiment Construction

[0018] Such as figure 1 Shown is a kind of urban greening modeling method in the present invention.

[0019] By analyzing the aerial images of the city, the greening plan obtained from the analysis is applied to the city model, including the following steps:

[0020] In step S1, the aerial image is analyzed to extract the distribution of streets, buildings and vegetation on the aerial image.

[0021] In step S2, the distribution of the streets, buildings and vegetation is analyzed, and a Gibbs distribution model of vegetation is established.

[0022] In step S3, according to the preset green coverage, the Gibbs distribution model of the vegetation is used to place the vegetation on the city model through the Monte Carlo-Markov chain mapping method.

[0023] Among them, the Gibbs model is a simple point distribution model, and its probability model can be expressed by a clear probability density function. Once such a function is available, it can be sampled to generate a set...

Abstract

The invention provides an urban greening modeling method which can be used for analyzing the urban aerial images and applying the afforestation plan obtained by the analysis into an urban model. The method comprises the steps of (1) analyzing the urban aerial images, and extracting the distribution situation of streets, buildings and vegetation on the urban aerial images; (2) analyzing the distribution situation of the streets, the buildings and the vegetation, and building a Gibbs distribution model of the vegetation; (3) putting the vegetation into the urban model by the Gibbs distribution model of the vegetation through a Monte Carlo-Markov chain mapping method according to the preset greening coverage degree. The urban greening modeling method can automatically complete the vegetation distribution in the urban model, and greatly reduces the work load of manually adding the vegetation into the urban model under the premise of being closer to the actual urban vegetation distribution situation.

Description

technical field [0001] The invention relates to smart cities, in particular to an urban greening modeling method. Background technique [0002] In recent years, with the development of computer graphics technology and the introduction of the concept of smart cities, the focus of modeling has gradually evolved from modeling a single object to modeling large-scale urban scenes. Existing technologies almost all focus on the planning, design and modeling of urban buildings and roads. However, for a complete urban scene, flora must be an indispensable component. [0003] Existing plant modeling work mainly focuses on the modeling of individual plants and the simulation of plant communities in the wild. For the modeling of plant communities in cities, there are only methods based on procedural modeling. However, when the procedural modeling method is applied to the vegetation placement on the city model, there are two main problems: [0004] Unreal visual effect: The vegetation...
