Research on the Application of Public Art Design Based on Digital Technology and Multisensor Fusion Technology in Urban Landscape Construction

During the more than 100 years of modern urban landscape design and construction, in addition to the continuous deductive changes of design thinking, concepts, methods and means, the construction concept and design thinking have also changed for a long time. In different periods, the degree of involvement and the role and the function of the public art involved in the landscape are different, and the applied technology is always changing. This paper emphatically analyzes the role of public art design of digital technology and multisensor fusion technology in the construction of urban landscape in China in recent years, and reveals that after the digital technology and multisensor fusion technology art design are involved in the construction of urban space landscape, they have shifted from the important power of shaping urban space aesthetics to the development of ecological aesthetics. At the same time, in this process, public art and urban design have developed to a new stage, that is, from the physical space to the construction of the spiritual field, which has become the most vivid visual text of today’s urban landscape, so as to further understand the significance and value of art in urban space.
