Rational Planning and Design of Urban Building Spatial Layout Based on Laser Point Cloud Algorithm

In order to meet the urgent needs of efficient urban planning and livable cities in modern society, the rational planning and design of urban building space layout is discussed based on laser point cloud algorithm. Reasonable planning and design of urban building spatial layout based on laser point cloud algorithm is a technology that uses laser scanner to obtain point cloud data of buildings, and then realizes reasonable planning and design of urban building spatial layout through processing and analysis. After filtering, registration and segmentation, the point cloud data obtained by laser scanner can obtain accurate geometric information of buildings. By analyzing this information, we can evaluate and optimize the location, shape and layout of urban buildings, so as to improve the quality and functionality of urban space. This technology provides important tools and data support for urban planners and architects, and helps to realize more reasonable and sustainable urban construction.
