Abstract:

In view of the characteristics of new high-speed bilateral observation digital level and staff(HSBODLS),the principle and method of measuring parameters both collimation axis height and angle i for HSBODLS are put forward based on the exchange measurement concept.The method of independent determination and non independent determination of collimation axis height and angle i are discussed in detail.The parameter equations and formulas are derived.Theoretical analysis and practical calculation show that non independent determination method for collimation axis height and angle i is more general and can be used as a standard determination method.At the same time,in practice,this paper holds that combined application of non independent determination method and independent determination method may be the best choice.Non independent determination method should be used when HSBODLS is installed initially and independent determination method should be used when the instrument height has been determined and unchanged in order to save time of measurement.

Key words: high-speed bilateral observation digital level and staff (HSBODLS), parameter determination, principle and method, collimation axis height and angle i.
