Block height step control method based on sunshine overlay analysis

Abstract

The invention discloses a block height step control method based on sunshine overlay analysis. According to the invention, the method includes performing gradient control on the internal height of theblock by taking sunshine right assurance of adjacent blocks as a target; firstly, extracting corresponding block data information from urban current situation surveying and mapping information; forming a sunlight control reference polygon according to the side lines of the adjacent blocks; making a ray by using each multi-deformation inflection point along the sun track point of the starting point of the corresponding time period; connecting all the rays to form a sunlight control inclined column body, staggering the sunlight control inclined column body with a vertical body quantity generated by the block to form a block sunlight overlay model to obtain a maximum height control value of the overlay model, and further performing correction and conversion according to a block height control gradient demand to obtain a final block height gradient control spatial distribution result. Based on rational analysis of the sunshine operation rule, block internal height control distribution isformed, the calculation method is simple and convenient, and judgment of the block internal building height at the initial stage of urban design is facilitated.

Description

technical field [0001] The invention belongs to the field of urban design, and in particular relates to a block height gradient control method based on sunshine cover analysis. Background technique [0002] The meso-scale block form control plays a role in linking the macro-urban structure and micro-building units in the urban environment. As an important unit in the study of urban form, its internal height control is an important content of urban design. In the rapid process of urbanization, block height control is not only affected by the overall urban pattern, landscape visual experience, and land economic value, but sunshine constraints are an important factor affecting block height, which is related to the health and safety of the urban environment and people's lives. [0003] The sunshine standard comes from the "Code for Planning and Design of Urban Residential Areas". The main control goal is to ensure the basic sunshine demand of a few types of buildings such as res...

Problems solved by technology

[0012] Based on the method of genetic algorithm, multi-agent, and deep learning of neural network, set relevant operation standards, and gradually approach the result of optimal height distribution combination through iterative operation or a large number of sample learning. This method can meet the sunshine requirements while ensuring , it is possible to obtain more forms, but it requires high professional skills for users, and requires a certain programming language foundation, and the degree of promotion in practical applications is restricted to a certain extent.
