The invention discloses a vehicle lane line crossing identification method and system based on a vehicle-mounted camera, and the method comprises the following steps: obtaining a traffic video in front of a vehicle through an automobile data recorder, and carrying out the frame extraction of the video according to a fixed frame interval through a computer, and dividing the video into a plurality of pictures; obtaining lane coordinate information and vehicle feature information of which the confidence degree reaches the standard through a lane detection module and a vehicle detection module on the picture subjected to frame extraction; the vehicle tracking module compares the similarity of the detected vehicles through the vehicle feature information, and continuously tracks the detected vehicles and updates the vehicle coordinate information in real time if the similarity reaches the standard; and finally, inputting the lane coordinate information and the vehicle coordinate information into a vehicle lane change identification module to judge whether the vehicle changes a lane or not. The method has the advantages of wide detection range, high detection precision, low detection cost and the like.
本发明公开了一种基于车载摄像头的车辆越车道线识别方法及系统,所述方法包括如下步骤:通过行车记录仪获取车辆前方的交通视频,计算机通过对视频进行按固定帧间距抽帧将视频分为若干张图片;经过抽帧后的图片分别通过车道检测模块和车辆检测模块得到置信度达标的车道坐标信息和车辆特征信息;车辆追踪模块通过车辆特征信息来比较检测车辆的相似度,相似度达标则持续追踪检测车辆并实时更新车辆坐标信息;最后将车道坐标信息和车辆坐标信息输入到车辆变道识别模块中来判断车辆是否变道。所述方法具有检测范围广、检测精度高且检测成本低等优点。
