Abstract: Aiming at the problems of Digital Twin (DT) production and processing system,data diversity and lack of efficient visual human-machine interface,a multi-view interactive method based on Augmented Reality (AR) was proposed for DT production and processing system.An information integration model for DT production and processing was established.Then the multi-view generation process of DT production and processing system was researched,which could dynamically realize virtual and real registration and dynamic tracking,and enhance the efficient collaboration between the operator and the processing system ability.By taking the machining process of aerospace structural part as an example,an AR-based digital replacement prototype processing system was established,which realized the efficient visualization of DT data,and verified the effectiveness and feasibility of the method.
