The invention discloses a road section multi-radar detection area track connection optimization method, which overcomes the problems that the detection range of a single radar is incomplete, the complete track of a vehicle on a middle road section cannot be obtained and the obtained track is easy to jump in the prior art, and comprises the following steps: S1, selecting a radar layout point location, and defining a radar connection area; s2, acquiring a target track set detected by a radar, and screening the target track set to obtain a target track set after duplicate removal; s3, judging whether the de-duplicated target track set is a multi-radar connection area or not, and performing same radar track connection or multi-radar track connection according to a judgment result; and S4, traversing all the target trajectories, and analyzing the remaining candidate trajectories to obtain a complete trajectory of the road section. By arranging the radars on the middle road section for same radar track connection and multi-radar track connection, complete track information of vehicles on the middle road section is obtained, the accuracy is high, matching is rapid, and meanwhile jumping is effectively prevented.
本发明公开了一种路段多雷达检测区域轨迹衔接优化方法,克服了现有技术中存在的单个雷达检测范围不全,无法获得中间路段上的车辆的完整轨迹、且获得的轨迹易出现跳变的问题,包括以下步骤:S1:选取雷达布设点位,界定雷达衔接区域;S2:获取雷达检测到的目标轨迹集合,对目标轨迹集合进行筛选,得到去重后的目标轨迹集合;S3:判断去重后的目标轨迹集合是否为多雷达衔接区域,根据判断结果进行同雷达轨迹衔接或多雷达轨迹衔接;S4:遍历所有目标轨迹,对剩余的候选轨迹进行分析,得到路段完整轨迹。通过在中间路段布设雷达进行同雷达轨迹衔接和多雷达轨迹衔接,得到了中间路段车辆完整的轨迹信息,准确度高、匹配快速、同时有效防止了跳变。
