The invention discloses a traffic signal information acquisition method and related equipment. The method comprises the steps that first scores of all traffic light groups are acquired based on intersection image information and an intelligent recognition algorithm, and the first scores are determined based on the matching degree of the intelligent recognition algorithm and traffic light feature information; a second score is determined according to the distance between the image position of the traffic signal lamp group and a preset position, and the preset position is a position where a target traffic signal lamp group obtained based on feature training is most likely to appear; determining the traffic signal lamp group with the maximum product of the first score and the second score as a target traffic signal lamp group; and identifying the color information and the shape information of the target traffic signal lamp group to obtain the traffic signal information of the current intersection. According to the method provided by the invention, traffic signal lamp matching is completed by taking deep learning traffic signal lamp group detection as assistance, the computing power is saved, the construction is fast, the cost is low, the precision is high, and sustainable development and optimization can be realized.

    本发明公开了一种交通信号信息获取方法及相关设备。该方法包括:基于路口图像信息和智能识别算法获取所有交通信号灯组的第一得分,其中,第一得分是基于智能识别算法和交通灯特征信息的匹配程度确定的;根据交通信号灯组的图像位置与预设位置的距离确定第二得分,其中,预设位置是基于特征训练后得到的目标交通信号灯组最容易出现的位置;将第一得分和第二得分的乘积最大的交通信号灯组确定为目标交通信号灯组;对目标交通信号灯组的颜色信息和形状信息进行识别以获取当前路口的交通信号信息。本申请提出的方法,通过深度学习的交通信号灯组检测作为辅助,完成交通信号灯匹配,节省算力,搭建快捷、成本低、精度高、可持续开发优化。
