Abstract

In the research of 3D linear scene construction, the scene construction method based on time or data is difficult to be event-centered, and there is the problem of data redundancy in the construction process. The event driver drives the change in the impact factor of an event during transaction dispatch by calling the corresponding event execution function to finally solve the problem and prevent the transaction from piling up. Based on linear reference model and event-driven, this paper proposes an event-driven model under linear reference system, and then realizes the construction of 3D linear scene driven by event model. Firstly, the basic event model is established by combining the characteristics of linear scene data band distribution. According to the types and logical relations of events in linear scene, the events are classified and the event coding rules under linear reference system are designed to make the event change drive the model attribute change in linear scene. The unified mapping relationship between events and objects is established, and the linear scene construction rules based on event-driven model are designed. Finally, experiments on the construction of dynamic highway scenes were conducted, and the construction of 3D linear scenes based on the event-driven model was realized, and the smoothness of scene rendering was significantly improved compared with the traditional method. The feasibility of efficient construction of 3D linear scenes based on event-driven model is verified. It is of great significance for highway emergency security.
