Urban three-dimensional skyline contour line automatic generation and diagnosis method based on shielding rate

Abstract

The invention discloses an urban three-dimensional skyline contour line automatic generation and diagnosis method based on a shielding rate. The method comprises the steps: with a Supermap GIS urban model platform and an augmented reality technology and equipment, taking the urban current three-dimensional building form and terrain elevation data as the basis, inputting an urban design scheme vector model, constructing a three-dimensional skyline contour line design scheme model, and automatically generating a skyline contour line orthographic image map of the design scheme and the urban current situation; rasterizing the orthographic image map, and then calculating a current skyline contour line and generating a shielding rate of the skyline contour line to the background mountain body; using a drawing device and a virtual image holographic interaction device for outputting an automatically generated urban three-dimensional skyline contour line scheme drawing and a virtual image. By means of real-time three-dimensional skyline contour line simulation and background mountain occlusion rate automatic diagnosis, an objective and efficient urban skyline diagnosis and evaluation methodis provided for planning managers and implementers.

Description

technical field [0001] The invention belongs to the technical field of skyline research and design in urban design, in particular to a method for automatically generating and diagnosing urban three-dimensional skyline contours based on occlusion rates. Background technique [0002] The city skyline is the overall or partial image formed by the high-rise buildings in the city and the background mountains, and it is an intuitive reflection of the results of urban planning and construction. In the process of quality urban space construction, the urban skyline shape not only attracts attention as an important visual aesthetic landscape of the city, but also as a spatial representation of urban economic and social development, it is increasingly valued and widely used by urban planners and managers. discuss. At present, the observation and evaluation research of urban three-dimensional skyline has become a key issue in the process of high-quality urban space construction, but mo...

Problems solved by technology

[0013] In general, the current generation and evaluation methods of urban skylines still have the following deficiencies: First, the current analysis of urban skylines only considers the overall facade image of the city, and the visual hierarchy of the skyline and the perspective of the actual environment Second, after the skyline is generated, there is a lack of an objective evaluation and diagnosis process for the skyline, which relies too much on the subjective and aesthetic evaluation of researchers, and lacks a set of scientific and objective methods. Finally, after the skyline scheme is generated, planning designers and planning managers cannot edit and view the new skyline outline in real time, lacking the interactive detection and control of the actual urban construction space
