驾驶模拟器是研究人-车-路3要素系统的重要工具。模拟器的真实性验证和参数标定是研究结论有效性和准确性的有效保证。本文首先对驾驶模拟器真实性验证的相关研究进行综述,基于标志在驾驶模拟器的呈现具有相对真实性的假设,建立指路标志在驾驶模拟中的参数标定流程。在模拟场景中考虑速度、文字高度因素,在真实场景中考虑速度因素,建立以可视距离为目标值的关系模型,最终得到20～40km/h速度范围内的指路标志修正系数。 Driving simulator is an important tool to study the system of people, vehicles and roads. Simulator authenticity verification and parameter calibration is an effective guarantee for the validity and accuracy of the conclusion. In this paper, firstly, the related researches on the verification of driving simulator are reviewed. Based on the assumption that the emblem is relatively authentic in the driving simulator, the parameter calibration flow of the driving marker is established. Considering the velocity and text height in the simulated scene, considering the speed factor in the real scene, the relationship model with the visual distance as the target value is established, and finally the correction factor of the road sign in the speed range of 20 ~ 40km / h is obtained.
