一、全站仪光电测距径向偏差法的测量方法全站仪光电测距径向偏差法测量的基本原理与光学垂准线法基本相同。如图1所示,全站仪架设在立式罐外侧周围的地面上,首先对基圆标志线进行圆周长测量(该基圆同样需要用围尺法求得半径),记录平距观测值,然后沿立式罐的母线,上下俯仰望远镜,把 First, the total station photoelectric measurement radial deviation method of measurement Total station photoelectric measurement of the radial deviation method of measuring the basic principles and optical vertical alignment method is basically the same. As shown in Figure 1, the total station is erected on the ground around the outside of the vertical tank. First, circle circumference measurement is performed on the marked circle of the base circle (the radius of the circle also needs to be determined by the radius method), and the observed horizontal distance , And then vertical bus along the tank, pitch telescope up and down, put
