Abstract

The invention provides a crowd behavior simulation method and apparatus, an electronic device and a storage medium. The method comprises the steps of determining a target perception domain and a target relative orientation of a target pedestrian; based on the target perception domain and the target relative orientation, determining the sharing proportion of the target pedestrian to the avoidance speed; based on the expected speed of the target pedestrian, determining a retreat avoiding half-plane line, the retreat avoiding half-plane line being used for limiting the feasible speed of the target pedestrian in a feasible solution region of the retreat avoiding half-plane line; and performing crowd behavior simulation through an ORCA model based on the sharing proportion and the back-off avoidance semi-plane line. According to the method, the basic ORCA model is improved by introducing the perception domain and the back-off avoidance configuration, the arch-shaped crowding phenomenon can be stably reproduced, and the sequence stability is achieved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a crowd behavior simulation method, device, electronic equipment and storage medium. Background technique [0002] Crowd behavior simulation is to study the behavior characteristics and laws of crowds in various scenarios, establish a simulation model of crowd behavior, and display the simulation process of crowd behavior realistically in a virtual environment. [0003] At present, when using electronic devices to simulate crowd behavior, the Optimal Reciprocal Collision Avoidance (ORCA) model is one of the classic microscopic crowd behavior simulation methods. With no collision as the goal, fully consider the distribution of avoidance responsibilities among pedestrians, solve the relatively optimal travel speed, and then simulate the travel process of the crowd. The basic ORCA model can achieve collision avoidance between multiple moving objects without central coor...
