Airport passenger shortcut system simulation environment construction method based on virtual reality

The invention provides an airport passenger shortcut system simulation environment construction method based on virtual reality. The method comprises the following steps: a three-dimensional model multi-node seamless coupling step, which is used for reproducing an airport passenger metro environment in a virtual simulation environment; a spatial position associated model feature description step for establishing and expanding a train operation simulation scene based on an airport passenger metro environment; a multi-mode train operation control step for establishing a motion relationship of atrain model in the train operation simulation scene and simulating an operation situation of the train on a real line; and a dynamic line-of-sight scene slice imaging step, which is used for realizingadaptive optimization configuration of display resources. According to the invention, the airport passenger metro environment can be reproduced, the train operation scene can be built and expanded, the operation situation of
