Design of the 3D Digital Reconstruction System of an Urban Landscape Spatial Pattern Based on the Internet of Things

Given the rapid development of modern science and technology, people are no longer satisfied with the planar composition and two-dimensional (2D) composition. Moreover, digitalization has entered the spatial layout of urban landscapes. The three-dimensional (3D) digital reconstruction technology can obtain the 3D effect map of urban garden landscapes, thereby improving the scientificity and timeliness of garden design. It is an important research direction in the field of computer vision. It transforms two or more planar graphics into visible 3D geometric graphics. It also restores their spatial coordinates and color information. The appearance of 3D digital reconstruction technology provides real-time and efficient information for landscape design, cost, and construction; improves the efficiency of landscape construction; and saves construction costs.
