Abstract

The invention discloses a method and a system for generating a near-line rate of a building, electronic equipment and a storage medium. The method for generating the near-line rate of the building comprises the following steps: projecting a three-dimensional model of a building to a plane parallel to the ground to form a building projection plane; obtaining the building length of the building according to the building projection plane; and according to the building length of the building and a preset frontage red line length, generating the near-line rate of the building, wherein the preset frontage red line length is the frontage red line length of a street corresponding to the building length. According to the invention, a building projection surface is formed by a building three-dimensional model, and the near-line rate of the building is calculated by performing spatial analysis on the projection plane of the building and the frontage red line; and the length of a building can be obtained by projecting the three-dimensional model of the building, so that the defect of inaccuracy caused by manual measurement of the length of the building is avoided, and the calculation efficiency of the line sticking rate is greatly improved.

Description

technical field [0001] The invention relates to the fields of computer graphics and national land planning, in particular to a method, system, electronic equipment and storage medium for generating a building line rate. Background technique [0002] The line rate refers to the percentage of the street wall facade composed of multiple building facades that should at least span the length of the block, that is, the continuity of the buildings facing the road and the degree of concession of the buildings on the ground floor. The ratio of the length of the red line, the higher the ratio, the more tidy the street looks. In the context of the development of urban planning towards refinement, the indicator of the line rate is getting more and more attention. Due to the complex shape of the building, in the prior art, the line rate is usually calculated by manually measuring the length of the building on the drawing, or the length of the building is measured on the three-dimensiona...
