The invention relates to an intersection overflow state recognition method, system and device based on radar data and a medium, and the method comprises the steps: obtaining the position information of an entrance stop line through radar software or a trajectory analysis radar, and introducing a map and/or trajectory analysis to calibrate the exit overflow detection range of each entrance of a target intersection; screening track points in an outlet overflow detection range to obtain a track point set; solving at least one state evaluation index based on the track point set; determining an outlet overflow state by comparing the state evaluation index with a preset state threshold value; and if it is determined that exit overflow occurs, determining existence and ending of an exit overflow event of the target intersection according to the collected continuous overflow times and continuous non-overflow times. According to the invention, through accurate space calibration, efficient data processing, scientific state evaluation and comprehensive event determination, the problem that the overflow identification capability of the existing radar trajectory technology in a complex and changeable urban traffic environment is limited is effectively solved.
本发明涉及一种基于雷达数据的路口溢出状态识别方法、系统、设备以及介质,其中,方法包括:通过雷达软件或轨迹分析雷达获取进口停车线的位置信息,引入地图和/或轨迹分析标定目标路口各进口的出口溢出检测范围;筛选出口溢出检测范围内的轨迹点,得到轨迹点集合;基于轨迹点集合,求取至少一项的状态评估指标;通过对比状态评估指标和预设的状态阈值,确定出口溢出状态;若确定发生出口溢出,根据采集的连续溢出次数和连续未溢出次数进行目标路口的出口溢出事件的存在和结束判定。本发明通过精确地空间标定、高效地数据处理、科学地状态评估及全面地事件判定,有效解决了现有雷达轨迹技术在复杂多变的城市交通环境中溢出识别能力受限的问题。
