1 导盲眼镜

世界卫生组织估计全世界盲人有4000~4500万。中国约有盲人600~700万，占世界盲人总数的18%，另有双眼低视力患者1200万。盲人生活中最大的问题是行走不便，特别是缺少头部保护装置，很容易受到空中悬挂物的伤害。由医学技术与护理学院张艳明老师（E-mail：zymgzzj@163.com）主持研发的导盲眼镜，是根据视觉生理前沿理论设计的一种新型盲人行走辅助设备，它能帮助盲人感知周围环境，靠近障碍物时，报警器会根据不同距离报警，使盲人接收耳机接收到报警信号，成为盲人行走的好帮手，保证盲人的出行安全。该仪器体积小，方便携带和使用。目前本产品开发成本较低，已生产出初级产品，可以向各级盲校、社区卫生医疗机构及盲人个体推广，改变盲人行走易受到突出物伤害的现状。

World Health Organization estimated that there are 40 million to 45 million visually-impaired people all over the world, 600 to 700 million of whom live in China, accounting for 18% of the total, with 12 million with low vision. Walking is a great challenge for the visually-impaired. The smart glassed developed by Prof. Zhang Yanming will help the visually-impaired detect obstacles and avoid injuries. With obstacles around, the alarmalertsaccording to the distance, the headset receives the alarm signal. The instrument is characterized by small size, easy operation and low cost. Therefore, it can be widely used in health care centers and schools for the visually-impaired or by the visually-impaired.

2 高级驾驶员辅助系统（ADAS）车载行车预警仪

汽车与交通学院梁伯栋高级工程师（E-mail：liangbodong@szpt.edu.cn）主持研发的ADAS车载行车预警仪，通过车载摄像头采样进行实时图像分析，并提供给驾驶员实时预警，主要具有以下功能：

1）车道偏离预警。车道偏离预警系统能够通过安装在挡风玻璃后的单目摄像头，实时检测地面上的车道线，并通过计算越线时间（TLC）去判断车辆是否即将越线。

2）前车避撞预警。前车避撞系统通过图像识别算法检测前方的车辆，并通过透视变换计算出前车离当前车辆的距离。再根据距离和相对速度，可以计算出虚拟碰撞时间（TLC），当TLC低于一定的阈值时，系统会发出声光报警以提醒驾驶员刹车减速。

3）行人避撞预警。当本车前方有行人接近时，预警仪会发出声光报警。

4）疲劳驾驶预警。通过安装在仪表盘上且正对着驾驶员脸部的摄像头，疲劳驾驶监测系统能够实时监测驾驶员的眼部状态，并通过算法分析眼部的睁闭状态来判定驾驶员是否处于疲劳状态。

5）开灯提醒。当驾驶环境光线不足时，例如进入隧道或地下室，系统会发出需要开灯的声光提醒。

6）前车起步提醒。在城市道路中跟车等红绿灯时，在此功能开启的状态下，当本车停驶5~10s后（具体可设置），系统开始检测前方车辆是否驶离，若是，系统会发出声音提醒。

With a single HD camera mounted behind the windshield, the ADAS Dashcam product can perform functions as follows:

1）Lane Departure Warning System (LDWS): The LDWS can detect the lane markings by using one singlecamera mounted on the windscreen behind the rearview mirror. Based on Time to Lane Crossing (TLC) calculation, the system can give a warning to the driver in case of unintentional lane departure.

2）Forward Collision Warning System (FCWS): The FCWS detects whether a crash is imminent by calculating the ‘Time to Contact’ (TTC) taking into account host vehicle speed, relative speed and relative acceleration. In case of emergency, a ‘critical’ warning is given to the driver.

3）Pedestrian Detection: by adopting advanced pattern recognition and classifiers with image processing and optic flow analysis, both static and moving pedestrians can be detected within the range of around 30m using VGA resolution imagers.

4）Fatigue Driving Detection System (FDDS): According to delicate changes of driver’s eyes, FDDS can detect fatigue driving.

5）Auto Light: Once the light environment is becoming dark, such as entering tunnel or basement, the system would alert driver to turn on the light.

6）Stop-Go: While waiting at the traffic light, after stopping for a predefined period (5 – 10s), the system would start to detect whether the frontal vehicle is leaving or not.
