The Determination of Total Station's Additive Constant with Triangle Method

摘要

Aiming at the situation that surveyors are difficult to determinate the additive constant and unable to set corresponding constant of the totall station when the lens's constant is unknown, propose the triangle law, which could determinate the lens's additive constant neglecting the effection of multiplication constant. As the triangle law's model is quite complex, it is too difficult to known the formula of precision, monte-carlo principle is used to calculate the additive constant and assess additive constant's accuracy in this model. Finally, illustrated the application of triangle method by an example.
