摘要
针对行车道路视野盲区会车过程中危险性高的问题,本研究以激光雷达连续探测迎面道路为基础,通过接收器接收激光脉冲反射回波信号计算视野盲区的车辆距离与时速。依据Kalman滤波的方式实时处理动态迎面车辆目标追踪,利用聚类的方式对视野盲区内的物体数量进行分组结果显示,同时,将显示器的硬件与单片机相连接实现数字信息传输的可视化,通过设置四种类型的会车辅助显示帮助行车中的驾驶员提高警觉性。最后选取不同的会车视距值对本研究设计的会车辅助系统进行实验测试,结果表明:车辆速度为25 km/h左右时,辅助系统的反应时间峰值仅达到1 s左右,这可为驾驶员在道路视野盲区的会车提供了紧急警示,帮助车辆安全会车行驶。
Carriageways blind spot for the car will be during high-risk problems, the present study, the continuous laser radar to detect oncoming road, based on the received laser pulses reflected echo signal calculation blind spot of the vehicle speed and distance through the receiver. Based on the Kalman filter in real time to handle dynamic oncoming vehicle target tracking, using clustering way of Objects, blind spot within the group showed that, at the same time, the display hardware and the microcontroller is connected to the visualization of digital information transmitted by setting four type of vehicle auxiliary display will help improve traffic in the driver＇s alertness. Finally, the car will select a different line of sight of the val- ue of the car will study design support system experimental test results showed that： Vehicle speed is 25 krrgh or so when the reaction time peak auxiliary system reached only about ls, which can be in the driver＇s blind spot in the road car will provide emergency alerts, safety car will help the vehicle is traveling.
