虚拟驾驶员视觉感知模型研究

视觉是驾驶员获得驾驶信息的主要通道,虚拟驾驶员的视觉感知模型是驾驶行为建模与仿真的重要内容,直接影响驾驶行为仿真的逼真度。介绍了四种视觉感知建模方法,根据视觉感知系统的反馈性和选择性,建立了视觉感知模型。在模型中,将视觉感知分为感觉和知觉两个过程,并引入了注意力、记忆力、驾驶疲劳和驾驶经验等因素,对每个因素进行分析。通过对虚拟驾驶员视觉感知模型的仿真实验,验证了该模型的可靠性和有效性,为驾驶行为研究提供了基础。

Research of virtual driver's visual perception model

Vision is the main channel of driving information for driver, the visual perception model of virtual driver is the imperative content of driving behavior modeling and simulation which affects the fidelity of driving behavior simulation. This paper introduced four methods of visual perception modeling. According to the feedback and selectiveness of vision, it established the visual perception model. It divided the visual perception into sensing and feeling and incorporated attention, memory, driving fatigue and driving experience into the model, further analyzed their effects on visual perception. By simulating the virtual driver's visual perception model, it validates the model which lay the foundation for driving behavior research.
