“The ”Suzhou Ancient City High-precision Multi-dimensional Data Fusion Laboratory" takes the Suzhou Historic District as the main research object and focuses on creating a digital twin base of the ancient city that can be seen, felt and known. The lab will focus on breaking through the technical bottlenecks of insufficient spatial data accuracy and simulation, and difficulties in multi-dimensional data fusion, so as to improve the modeling accuracy and application depth in the field of digital twins. The research directions include: improving the precision and simulation of spatial models to realize the visual reproduction of the ancient city; exploring the automated semantic segmentation and multidimensional data hook-up mode based on artificial intelligence to realize the intelligent perception of the ancient city; and researching the algorithm for generating the design scheme of the ancient city to help the protection and updating work of the ancient city.
