The invention relates to the technical field of automatic driving, in particular to a traffic signal state detection method and device and a storage medium. The method comprises the steps that traffic behavior information of a target intersection is acquired, the target intersection is an intersection where a traffic signal lamp in the vehicle driving direction is located, and the traffic behavior information indicates the behavior of at least one traffic participant; according to the traffic behavior information, a state detection result of the traffic signal is determined, the traffic signal comprises a traffic signal lamp or a gesture signal of a traffic police, and the state detection result indicates the state of the traffic signal. According to the embodiment of the invention, the state of the associated traffic signal is reversely predicted through the traffic behavior information of the target intersection, so that the condition that the traffic signal state detection is realized only through traffic signal image perception in the related technology can be avoided, and the accuracy of traffic signal state detection is improved.
本申请涉及自动驾驶技术领域,尤其涉及一种交通信号状态检测方法、装置及存储介质。所述方法包括:获取目标路口的交通行为信息,目标路口为车辆行驶方向的交通信号灯所处的路口,交通行为信息指示至少一个交通参与者的行为;根据交通行为信息,确定交通信号的状态检测结果,交通信号包括交通信号灯或者交警的手势信号,状态检测结果指示交通信号的状态。本申请实施例通过目标路口的交通行为信息反向预测出关联交通信号的状态,可以避免相关技术中仅依靠交通信号图像感知来实现交通信号状态检测的情况,提高了交通信号状态检测的准确率。
