Skyline evaluation method based on city live-action long volume and three-dimensional model projection

Abstract

The invention discloses an skyline evaluation method based on city live-action long volume and three-dimensional model projection, and the method comprises the following steps: S1, building regional,hierarchical, and classified city current situation skylines based on city live-action long volume; S2, performing three-dimensional modeling on the building scheme, and performing facade projection on the building scheme according to the observation point; and S3, based on the city live-action long volume, superposing the city current situation skyline and the building scheme elevation projection, and carrying out skyline evaluation on the building scheme. The skyline evaluation method based on the city live-action long volume and the three-dimensional model projection is not high in softwareand hardware requirements, high in realizability, low in manufacturing cost and short in production period. Since the shot real-scene image is used as the background, the authenticity is high. Vectorachievements of different areas, different levels and different types are formed respectively, so that the skyline hierarchy is stronger, and analysis and planning are more convenient.

Description

technical field [0001] The invention relates to the field of digital city planning, in particular to a skyline evaluation method based on urban real-scene scrolls and three-dimensional model projections. Background technique [0002] The city skyline is a symbol of the city, embodies the overall outline of the city, and is the most concentrated and typical embodiment of the city's style and image. The city skyline is a contour line composed of various topography and features with the sky as the background, and is a vertical spatial projection of the overall appearance of the city. Kevin Lynch pointed out in "The Image of the City" that a good urban visual quality has distinct recognizability, including roads, edges, nodes, regions and signs, which have certain image characteristics, clear structure, and easy to identify. A city skyline is a boundary element, a starting point and an important factor in establishing the impressionability of a city. [0003] The city skyline ...

Problems solved by technology

[0009] The existing technology can better solve the problem of urban skyline generation, but there are also the following deficiencies: it is difficult and costly to build high-precision models of the basic terrain, landforms, and buildings of the city; the existing technical solutions require high-end software and hardware The environment can simulate city-level planning schemes; the current skyline analysis only considers visibility, does not distinguish between different regions, different levels, and different categories, and does not take into account the different requirements of different regions and different categories for skyline evaluation
