The invention relates to the field of vehicle safety, in particular to a method for tracking a non-motorized vehicle lane blind area in right steering at a vehicle intersection, and a corresponding device and system thereof. The method comprises the steps that S1, the steering wheel rotation angle of a vehicle is obtained in real time, and the vehicle rotation angle is calculated according to the steering wheel rotation angle and vehicle body parameters of the vehicle; and S2, acquiring an image picture of a non-motorized vehicle lane on the right side through a blind area camera mounted on the vehicle body, calculating a center coordinate of a blind area position according to the image picture, and representing the center coordinate as a parameter related to a vehicle turning angle. S3, based on the center coordinates of the blind area, the rotation relation between the holder rotation angle of the blind area camera and the vehicle rotation angle is obtained; and dynamically adjusting the rotation angle of the holder of the blind area camera so as to enable the optical center direction of the blind area camera to coincide with the center coordinate of the blind area. The problem that in the prior art, it is difficult to observe the traffic condition of the non-motor vehicle on the right side in real time during right turning is solved, and then the traffic safety accident rate is effectively reduced.
本发明涉及车辆安全领域,特别是涉及一种车辆路口右转向中非机动车道盲区的跟踪方法,及其对应的装置和系统。该方法包括:S1:实时获取车辆的方向盘转角,并根据方向盘转角以及车辆的车身参数计算出车辆转角。S2:通过车身上安装的盲区摄像头获取右侧非机动车道处的影像画面,根据影像画面计算出盲区位置的中心坐标,并将其表示为与车辆转角相关的参数。S3:基于盲区的中心坐标,得到盲区摄像头的云台转角与车辆转角之间的转动关系;动态调整盲区摄像头的云台转角,以使得盲区摄像头的光心方向与盲区的中心坐标重合。本发明解决了现有技术难以实现在右转弯时对右侧非机动车的交通状况进行实时观察的问题,进而有效降低交通安全事故发生率。
