The invention discloses a method and a system for guiding parking spaces in a parking lot based on video streams. The method comprises the following steps: collecting video streams of intersections and corresponding roads in the parking lot in real time; performing image recognition according to the video stream, and analyzing to obtain license plate information and a driving track of the vehicle; taking cameras of all intersections in the parking lot as nodes, taking roads corresponding to the intersections as paths, and constructing the parking lot into a graph structure which is divided into regions according to the paths; analyzing the driving track of a single vehicle, and dynamically calculating the number of vehicles entering and exiting each area in the graph structure based on graph calculation; and dynamically calculating the number of empty parking spaces in each region according to the preset number of parking spaces in each region, and dynamically displaying the number of the empty parking spaces in the corresponding intersection region by region. Through the technical scheme of the invention, the number of the empty parking spaces guided to each area can be calculated and displayed in real time, rapid and accurate empty parking space guiding in the parking lot is realized, the parking space searching time of a vehicle owner is reduced, and the parking experience is improved.

    本发明公开了一种基于视频流的停车场内部车位引导方法及系统,方法包括:实时采集停车场内部交叉路口和对应道路的视频流;根据视频流进行图像识别,分析得到车辆的车牌信息和行驶轨迹;以停车场内所有交叉路口的相机为节点、以交叉路口对应道路为路径,将停车场构建为以路径进行分区域的图结构;对单个车辆的行驶轨迹进行分析,并基于图计算动态计算进出图结构中各区域的车辆数;根据各区域的预设车位数动态计算每个区域的空车位数量,并在相应的交叉路口分区域进行动态展示。通过本发明的技术方案,能够实时计算并显示引导至各个区域的空车位数量,实现了停车场内部快速、准确的空车位引导,减少了车主的寻找车位时间,提升了停车体验。
