The invention discloses a real-time data driven crowd behavior modeling simulation method oriented to digital twinning. The method comprises the following steps: constructing a three-dimensional twinning static scene structure and a two-dimensional simulation scene structure; collecting video data of crowd dynamic changes in the dynamic scene structures in the plurality of time windows in real time; obtaining a macroscopic crowd motion flow and crowd density distribution of each time window; distributing the macroscopic crowd motion flow and the crowd density distribution into each unit area, and obtaining a motion flow set and an accumulated density error of each unit area; obtaining migration adjustment requirements and migration adjustment quantities of the agents in each unit area; and obtaining the preferred speed of the agent in each unit area, obtaining the obstacle avoidance speed, and generating a three-dimensional dynamic crowd corresponding to the dynamic scene structure time in the three-dimensional twin static scene structure. The method can fully meet the application requirements of a digital twinning scene, and has the characteristics of high fidelity and high restoration.
