Example 1
And measuring the horizontal distance and the elevation of the point to be measured along the roadway with the slope along the straight line.
As shown in figure 2, when a steep slope is arranged in front of a straight roadway and a total station cannot be erected at a slope rising position due to factors such as water damage, the elevation of a point to be measured needs to be measured at the top of the slope, an instrument can only be erected at a lead point far away from the slope rising position to observe the point to be measured and cannot see the point to be measured, when the instrument is applied, a refractor is arranged at the slope rising position, laser infrared rays of the total station instrument are turned on, the laser infrared rays irradiated on the top of the refractor (the vertical angle of the refractor is 90 degrees under the condition that the vertical angle of the refractor is not displayed in an 'angle setting state') are irradiated on the top of the refractor, the laser infrared rays are irradiated on the point to be measured through adjustment, a measurer aligns to the laser infrared rays through a single prism, then the laser is turned off, the vertical angle of the instrument is locked, the zenith distance is recorded, the distance measured at the center of the single prism is calibrated through the instrument, the height, and the elevation of the point to be measured can be obtained through calculation.

d + e is the horizontal distance from the wire point to the point to be measured.
c=a*cosδ+b*cos(180°－δ）
H = wire point elevation-instrument height + occupied elevation + c
d+e=(a+b)*sinδ
Example 2
