The invention provides a vehicle-mounted pedestrian early warning system. The vehicle-mounted pedestrian early warning system comprises an image acquisition module, an image recognition module, a distance judgment module and a prompt module; The system comprises the steps of acquiring an infrared image in front of a vehicle through the image acquisition module; carrying out pedestrian detection onthe infrared image through the image recognition module, judging whether a pedestrian exists in the infrared image or not, and if the pedestrian exists, marking the pedestrian in the infrared image to obtain an infrared marked image; enabling a distance judging module to calculate the distance d from the pedestrian to the vehicle, then judging whether d is smaller than a preset warning thresholdvalue dthre or not, and if d is smaller than dthre, sending a starting signal to the prompt module; and the prompting module being used for sending out an alarm sound to prompt a driver after receiving the starting signal. When the sight of the driver is disturbed or the driver is distracted, pedestrians in front of the vehicle can be found in advance, and then an alarm sound is given out to prompt the driver.
本发明提供了一种车载行人预警系统,其包括图像获取模块、图像识别模块、距离判断模块、提示模块;通过图像获取模块获取车辆前方的红外图像;然后通过图像识别模块对红外图像进行行人检测,判断其中是否存在行人,若存在行人,则在所述红外图像中对所述行人进行标记,得到红外标记图像;并通过距离判断模块计算行人到车辆的距离d,然后判断d是否小于预设的警戒阈值dthre,若d<dthre,则向提示模块发送启动信号;所述提示模块用于在接收到所述启动信号后,发出警报声提示司机。本发明可以在司机的视线受到干扰或司机注意力不集中时,提前发现车辆前方的行人,然后发出警报声提示司机。
