Research on Colour Correlation in Urban Space Design Based on Remote Sensing Image Fusion Algorithm

With economic and social development, urbanisation is accelerating and human activities are increasingly interfering with the natural environment, leading to a series of ecological and environmental problems. To solve these problems, rational planning and management of cities is required. One of the important tools is to guide urban construction through urban colour landscapes. At present, many large and medium-sized cities in China have the phenomenon of “a thousand cities in one”, which not only affects people's quality of life, but also restricts the shaping of urban characteristics. Therefore, how to use remote sensing technology to obtain high-resolution satellite images and combine with GIS platform to achieve multi-source data integration application has become one of the current research hotspots. The experimental results show that the composition integrity of urban space design colors based on remote sensing image fusion algorithm can reach up to 94.8%.
