Method for quickly acquiring precise position of road marking
The invention relates to a method for quickly acquiring a precise position of a road marking. The method comprises the steps of: keeping a satellite antenna, a detection light source and a detection sensor relatively fixed, and enabling them to travel in a road marking track direction; using the satellite antenna as an origin, establishing three-dimensional coordinate system, acquiring a coordinate position of the satellite antenna in an initial state as an origin coordinate; constructing projection points of the satellite antenna, the detection sensor and a to-be-detected marking on a horizontal plane; connecting the three projection points in sequence, and solving the distances and included angles of the connecting lines; and carrying out conversion to obtain the longitude and latitude of the to-be-detected marking in combination with the positioning position and direction of the satellite antenna. Compared with hand-held measurement, the method utilizes vehicle driving to complete measurement, the measurement efficiency of the scheme is several times of that of manual measurement, and meanwhile, the satellite antenna is utilized, so that the precision of the position of the marking to be measured is greatly improved, and the measurement error is reduced.
本发明涉及一种快速获取道路标线精准位置的方法，该方法将卫星天线、检测光源、检测传感器保持相对固定，使其沿道路标线轨迹方向行驶；以卫星天线作为原点，建立三维坐标系，获取初始状态下卫星天线的坐标位置作为原点坐标，构建卫星天线、检测传感器、待测标线在水平面上的投影点，将三点依次连接，求出各连线距离和夹角，结合卫星天线定位位置及方向，即可换算出待测标线的经纬度，和手持式测量相比，本方案利用车辆行驶完成测量，其测量效率是人工测量的数倍，同时利用卫星天线，极大地提高了待测标线位置的精度，减小了测量误差。
