摘　　要：以往车辆交通环境实时感知方法传感器灵敏度较差,无法适应复杂多变环境要求。光纤传感器可输出有用信号与补偿信号两路信号,提升不同情况车辆交通环境感知精度。研究基于光纤传感器的车辆交通环境实时感知方法,依据光纤传感器感知原理建立交通环境实时感知结构,结构中的信息采集部分通过光纤传感器与IP摄像机采集环地上环境信息后,利用信息处理部分分割地面与地上环境信息,获取可行驶区域,通过K-Means方法聚类可行驶区域内地上目标,获取目标列表,利用叠加栅格网与目标表面特征匹配方法识别目标列表中的目标,采用扩展卡尔曼方法跟踪目标列表中的目标,融合识别目标和感知目标,感知目标通过信息显示部分展示。实验结果表明,该方法在晴朗、阴雨、雾霾天气下,加入白噪声和交通拥堵情况下,对车辆交通环境的实时感知准确率均较高,且该方法的车辆交通环境感知时间和能耗均较低。In the past,the sensor sensitivity of real-time vehicle traffic environment sensing method is poor,and it cannot meet the requirements of complex and changeable environment.Fiber optic sensor can output useful signal and compensation signal to improve the vehicle traffic environment sensing accuracy in different situations.The real-time sensing method of vehicle traffic environment based on optical fiber sensor is studied.The real-time sensing structure of traffic environment is established according to the sensing principle of optical fiber sensor.After collecting environmental information through optical fiber sensor and IP camera,the information processing part is used to segment the information of ground and ground environment to obtain the feasible driving area.The K-Means method is used to cluster the recognition of the feasible driving area.For each target,the superimposed grid matching method is used to obtain the target list,and the extended Kalman method is used to track perceptual target,and the perceptual target is displayed through the information display part.The experimental results show that the real-time sensing accuracy of vehicle traffic environment is high under the conditions of white noise and traffic jamming in the sunny,rainy and haze weather,and the sensing time and energy consumption of vehicle traffic environment are low.
