The invention provides a traffic signal lamp recognition method and device. The method comprises the steps: obtaining the signal lamp data of a to-be-recognized traffic signal lamp; recognizing a first signal lamp state of the to-be-recognized traffic signal lamp at the current moment according to the signal lamp data; updating a counting value according to the first signal lamp state and a second signal lamp state at the previous moment; and determining the corresponding first signal lamp state when the updated counting value reaches a preset threshold value as the signal lamp state of the signal lamp to be recognized. And after the counting value is accumulated to the preset threshold value, the first signal lamp state at the current moment is output, so that the probability of signal lamp state recognition errors caused by jumping of the to-be-recognized traffic signal lamps in the process of analyzing the to-be-recognized traffic signal lamps is greatly reduced, and the signal lamp data of the plurality of to-be-recognized traffic signal lamps are obtained, thereby improving the recognition accuracy of the to-be-recognized traffic signal lamps. And the signal lamp state is obtained by combining the signal lamp data of the plurality of to-be-recognized traffic lamps, so that the influence of a complex scene on an recognition result can be reduced.

    本发明提供了一种交通信号灯识别方法及装置,其中,该方法包括:获取待识别交通信号灯的信号灯数据;根据信号灯数据识别待识别交通信号灯当前时刻的第一信号灯状态;根据第一信号灯状态和上一时刻的第二信号灯状态更新计数数值;将更新后的计数数值达到预设阈值时所对应的第一信号灯状态确定为待识别信号灯的信号灯状态。在计数数值累加到预设阈值后输出当前时刻的第一信号灯状态,极大地减小了在对待识别交通灯进行分析过程中待识别交通信号灯出现跳变导致的信号灯状态识别出现误差的概率,并且,获取多个待识别交通信号灯的信号灯数据,并结合多个待识别交通灯的信号灯数据得到的信号灯状态,也可以减小复杂场景对识别结果的影响。
