Application and Method of Stadia Asymmetrical-like Leveling

Other than the traditional stereotype of rigid symmetry should be observed between the back and fore sight range of optical simulation leveling,the method introduced in this paper takes the level's i-angle error as an unknown variable involving in the process of adjustment.This sees no less precision of measurement or even a better one,and makes the leveling much easier and more efficient.This paper demonstrates the effectiveness of such method form the angle of physical mechanism,mathematical deduction and practical tests.
