Embodiment Construction
[0049] Before the measurement, fix the leveling distance measuring prism to the centering rod, adjust them to the same height, and fix the centering rod to ensure that its height remains unchanged during the measurement process.
[0050] The form of measurement is similar to that of leveling. The total station is leveled between the front and rear viewpoints, and the centering rod leveling distance measuring prisms of equal height are respectively erected on the front and rear viewpoints.
[0051] The erection point of the total station is as far as possible in the middle of the front sight point and the rear sight point, so that the front and rear sight distances are nearly equal. In this way, the measurement errors caused by spherical aberration, air difference and i-angle of the total station can all be offset.
[0052] First align the center of the reticle of the total station telescope with the center of the backsight point reflective prism, measure the distance, and reco...
