Immersive pedestrian traffic behavior experiment platform and method based on virtual reality technology

Abstract

The invention relates to an immersive pedestrian traffic behavior experiment platform and method based on a virtual reality technology. The platform is composed of a scene construction module, head-mounted VR glasses, a universal walking pad, a 3D camera device, an action recognition module, a control module, a data collection and export module and a physiological data sensor. The invention also provides a pedestrian traffic behavior experiment method based on the virtual reality technology, and the method comprises the steps: 1, experiment scene construction: selecting a reconstruction mode based on a real scene or directly employing a simulation software compiling mode for the construction of the experiment scene according to the experiment requirements; 2, parameter setting: according to experiment requirements, event insertion and related parameter setting are carried out on an experiment scene; 3, equipment connection and test: operating control software to complete port test andconnection test, and establishing connection for control programs of different equipment; 4, formal experiment and data acquisition. Compared with the prior art, the platform and the method have the advantages of fitting the actual situation, being high in experiment environment authenticity and the like.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic systems, in particular to an immersive pedestrian traffic behavior experiment platform and method based on virtual reality technology. Background technique [0002] When studying traffic behavior, it is very difficult and error-prone to use the mathematical model method to analyze traffic behavior theoretically, and the field experiment is limited by the conditions of the actual scene and has great safety hazards. Therefore, the simulation experiment is very important when studying traffic behavior. The most commonly used means. According to research, most of the research on traffic behavior in China is currently carried out on vehicle drivers. The driving simulator experiment platform is relatively mature, but there is little research on pedestrian traffic behavior, and there is a lack of simulation experiments on pedestrian traffic behavior from the perspective of pedestrians. platf...
