The invention provides a traffic light state acquisition method and device, electronic equipment and a storage medium, and the method comprises the steps: determining the ID of an intersection which is about to pass through in a vehicle driving path through the current position of a vehicle, obtaining the phase ID of a traffic light through the matching of the intersection ID, and further determining the light state of the traffic light. The method for obtaining the lamp state and the countdown time of the traffic light phase at the current position of the vehicle according to the map matching algorithm can be achieved based on an existing traffic guidance platform, a road network map and a vehicle-mounted intelligent terminal, traffic light equipment does not need to be transformed, the method is not affected by weather, the required data size and the calculated amount are calculated, and the recognition accuracy is high.
本发明提供了一种红绿灯状态获取方法、装置、电子设备和存储介质,通过车辆的当前位置确定车辆行驶路径中即将经过的路口ID,并根据路口ID匹配得到红绿灯相位ID,以进一步的确定红绿灯的灯态,相对现有技术而言,本发明根据地图匹配算法获取车辆当前位置红绿灯相位的灯态与倒计时时间的方法,基于现有的交通指挥平台、路网地图、车载智能终端即可实现,不需要对红绿灯设备进行改造,且不受天气影响,计算所需的数据量、计算量小,识别准确率高。
