分析了驾驶人视野注视点的移动规律,研究了空间视野范围内的视野水平角,给出了车速与视野和注视距离的关系,提出了空间视野感知模型。结合道路中心线与平行线三维坐标计算方程,建立了驾驶人空间视野感知模型的计算方法。通过计算机模拟实际场景,对5位受试者分别进行了4次测试,得到了722段组合数据和3585个速度数据,对模型进行了验证。研究结果表明:预测结果与实测结果吻合率大于70%,不明显效果率低于20%,错误效果率低于10%。该模型仿真效果明显,算法易于实现。
This paper analyzes the movement rule of the driver’s gaze point, studies the horizontal angle of the field of view in the field of vision, gives the relationship between the vehicle speed and the field of view and the gaze distance, and proposes the perception model of the space vision. Combined with the three-dimensional coordinate calculation equations of road centerline and parallel lines, the calculation method of driver’s perception model of space vision is established. Through computer simulation of the actual scene, the five subjects were tested 4 times respectively, and the combined data of 722 segments and 3585 velocity data were obtained, and the model was verified. The result shows that the coincidence rate between the predicted result and the measured result is more than 70%, the insignificant effect rate is less than 20% and the false effect rate is less than 10%. The simulation results show that the algorithm is easy to implement.
