The invention discloses a traffic scene twinning method and device, and the method comprises the steps: obtaining the geographic information data of a road, enabling the geographic information data to comprise the geographic coordinates of the road, mapping the center line direction of the road to be the x direction and the width direction of the road to be the y direction in a twinning image of the traffic scene, building a rectangular coordinate system, and generating a two-dimensional graph of the road, and determining the x coordinate of any point in the two-dimensional graph and the cumulative length of the position of any point in the three-dimensional geographic information data corresponding to the road along the direction parallel to the center line of the road. The invention further comprises a device for implementing the method. By adopting the method, the actual road condition and the road equipment can be accurately and synchronously reflected to a picture, and accurate road monitoring is facilitated.
本申请公开了一种交通场景孪生方法和装置,该方法包括获取道路地理信息数据,地理信息数据中包含道路的地理坐标,在交通场景的孪生图景中,道路的中心线方向映射为x方向,道路的宽度方向映射为y方向,建立直角坐标系,生成道路的二维图形,确定二维图形中任意一点的x坐标,对应于道路的三维地理信息数据中的任意一点的位置沿平行于道路中心线方向的累积长度。本申请还包含用于实现所述方法的装置。采用该方法能够达到将实际路况和道路设备精准且同步反映至画面,便于道路精准监控。
