, be respectively levelling staff A corresponding to true horizon sight line and B reading, do not have icorrect reading when angle affects.
By above-mentioned formula, can try to achieve in real time spirit-leveling instrument iangle is:
Or:
Above-mentioned two formulas can check mutually.
Can eliminate spirit-leveling instrument simultaneously ithe impact of angle on elevation observed reading:
Further can eliminate spirit-leveling instrument ithe high difference at angle for:
Obviously, high difference and the distance in above-mentioned formula , irrelevant.The data processing principle of the utility model embodiment 1 has thoroughly overcome the spirit-leveling instrument of the spirit-leveling instrument existence of traditional single observation passage iangle and require spirit-leveling instrument to equate the technical matters of bringing apart from the horizontal range of two levelling staffs.
