The invention discloses an infrared pedestrian projection display method and system for night driving. The infrared pedestrian projection display method for night driving comprises the following steps of (1) collecting position information of pedestrians in front of a night vehicle through infrared signals and radar signals, and performing data processing and recognition; (2) acquiring a midpoint between two eyes of the driver as a viewpoint through camera shooting, and performing data acquisition and calculation; (3) calculating a lateral construction line segment according to the position information of the pedestrian, the viewpoint and the position of a front windshield of the vehicle; (4) further calculating to obtain an actual projection line segment of the pedestrian on the front windshield; and (5) broadcasting the real-time distance between the pedestrian and the vehicle through voice. The system for implementing the method comprises an infrared camera, a millimeter wave radar, a binocular camera, a projector and a control module. A driver only needs to observe the pedestrian projection image on the front windshield to determine the specific orientation and distance information of the pedestrian ahead, so that early warning can be carried out in advance.
本发明公开了一种夜间行车的红外行人投影显示方法及系统。一种夜间行车的红外行人投影显示方法,包括以下步骤:(1)通过红外信号和雷达信号采集夜间车辆前方的行人位置信息,并进行数据处理和识别;(2)通过摄像获取驾驶员两眼之间的中点为视点,并进行数据获取和计算;(3)根据行人位置信息、视点及车辆的前挡风玻璃位置计算得出侧向构建线段;(4)进一步计算得出行人在前挡风玻璃上的实际投影线段;(5)语音播报行人与车辆的实时距离。实施该方法的系统,包括红外摄像机、毫米波雷达、双目摄像头、投影机和控制模块。本发明中驾驶员只需观察前挡风玻璃上的行人投影图像就可确定前方行人的具体方位及远近信息,以便提前预警。
