在行车繁忙的线路上,采用光电测距仪任意点置镜极坐标法(简称“坐标法”)测量曲线,可以减少置镜次数和行车干扰,是行之有效的方法,文中详细介绍了该法的外业作业要求。外业资料可按[1]所述的方法,即三点坐标法进行内业校正计算。针对三点坐标法存在的问题,建议将实测坐标化为实测偏角,按改进后的偏角方法进行内业校正计算,通过实例计算比较,证明是可行的,且有一定的优越性。
It is an effective method to measure the curve by using any point of the photoelectric range finder (referred to as “coordinate method”) on busy lines to reduce the number of mirrors and driving interference. France’s job requirements. Field data can be described in [1], that is, three-point coordinate method for home calibration. According to the existing problems of three-point coordinate method, it is suggested to coordinate the measured data into the actual measured one. Based on the improved two-point method, the calibration of the inner area is proposed. It is proved that it is feasible and has certain advantages.
