基于全方位视觉传感器的驾驶疲劳视频检测装置的设计

针对驾驶疲劳问题,设计了一种基于全方位视觉传感器的驾驶疲劳视频检测装置;首先使用全方位视觉传感器采集到驾驶员脸部、方向盘和道路环境的视频信息,接着采用图像识别手段检测各种能反应驾驶员疲劳的因素,如驾驶员的感知疲劳、判断疲劳和动作疲劳,最后根据以上所检测到的信息综合判断驾驶员是否处于驾驶疲劳状态;实验结果表明,该检测装置能有效地减少驾驶疲劳的漏判率和误判率。

Design of Drowsy Driving Video Detecting Device Based on Omni-directional Vision Sensor

Towards the drowsy driving,a kind of drowsy driving video detecting device based on omni-directional vision sensor(ODVS) is designed.The device first uses the Omni-directional Vision sensor to collect the information of the driver's face,the steering wheel and the roadway environment,then uses the image recognition technology to detects all factors which can reflect the tired condition of the driver,such as the driver's apperceive tiredness,judgemental tiredness and operational tiredness.Finally the device judges whether the driver is tired according to all the information detected above.The result of experiment shows that the device can reduce the possibility of misjudge effectively.
