The invention discloses a vehicle driving track calculation and restoration method, and belongs to the technical field of vehicle driving track restoration. The problems that in the prior art, historical data needs to be manually called for analysis when traffic road condition analysis is conducted through a traditional vehicle driving track reduction method, and the analysis data size is large are solved. The method comprises the following steps: performing multi-attribute data identification calculation on a vehicle running on a road through a common camera on a road side to obtain running track point data; according to the vehicle driving direction and the driving track point data, a vehicle head driving angle is obtained through calculation, conversion between a two-dimensional coordinate system and a real world coordinate system is carried out, and the driving speed of the vehicle is obtained; and packaging and uploading the collected driving track point data to a database, finally performing curve fitting processing on the vehicle track point data in a certain time period in the database, and drawing a restored vehicle driving track. The method effectively improves the precision and efficiency of vehicle driving track restoration, and can be applied to traffic road condition analysis.
本发明公开了一种车辆行驶轨迹计算还原方法,属于车辆行驶轨迹还原技术领域。解决了现有技术中传统的车辆行驶轨迹还原方法在进行交通路况分析时需要人工调用历史数据分析且分析数据量较大的问题;本发明通过道路侧普通摄像头,对道路上行驶的车辆进行多属性数据识别计算,得到行驶轨迹点数据;根据车辆行驶方向和行驶轨迹点数据,计算得到车头行驶角度,进行二维坐标系和真实世界坐标系的转换,得到车辆的行驶速度;将采集到的行驶轨迹点数据打包上传到数据库,最后对数据库某个时间段的车辆轨迹点数据进行曲线拟合处理,绘制还原后的车辆行驶轨迹。本发明有效提升了车辆行驶轨迹还原的精度和效率,可以应用于交通路况分析。
