The invention discloses a road congestion reason acquisition method, system and device based on an intelligent traffic light, and the method comprises the steps: obtaining the current traffic light information of the intelligent traffic light if a background server determines that a plurality of vehicles are parked at an intersection based on an image collected by an image collection device; if yes, obtaining a congestion identification result based on a congestion identification model; if the congestion identification result is determined to be traffic jam, generating an unmanned aerial vehicle aerial photographing instruction and sending the instruction to the intelligent unmanned aerial vehicle; the intelligent unmanned aerial vehicle correspondingly collects multiple frames of aerial traffic pictures at the current intersection based on the unmanned aerial vehicle aerial photographing instruction and sends the aerial traffic pictures to the background server; and identifying and determining road congestion reason information based on the aerial traffic picture of the current intersection. According to the embodiment of the invention, when it is determined that the road congestion exists based on the current road condition picture set uploaded by the image acquisition device, the intelligent unmanned aerial vehicle carries out aerial photography to acquire the aerial photography traffic picture set of the current intersection, so that the reason of the road congestion can be determined more quickly and accurately.

    本发明公开了基于智能交通灯的道路拥堵原因获取方法、系统及设备,方法包括:若后台服务器基于图像采集装置采集的图片确定路口存在多车辆停车,则获取智能交通灯的当前红绿灯信息;若其对应绿灯显示状态,则基于拥堵识别模型得到拥堵识别结果;若确定拥堵识别结果为存在堵车,则生成无人机航拍指令并发送至智能无人机;智能无人机基于无人机航拍指令对应采集多帧当前路口航拍交通图片并发送至后台服务器;基于当前路口航拍交通图片进行识别确定道路拥堵原因信息。本发明实施例可以基于图像采集装置上传的当前道路路况图片集确定存在道路拥堵的情况下,由智能无人机进行航拍采集当前路口航拍交通图片集以用于更快速精准的确定道路拥堵原因。
