INSTRUMENTATION SYSTEM USING ALIGNMENT SCOPE AND METHOD FOR DETERMINING SYSTEM PARAMETERS OF ALIGNMENT SCOPE

摘要

PURPOSE: An instrumentation system using the alignment system and a method for determining a system variable are provided to accurately measure a location and posture information of a working object by determining s real system variable value of an alignment system according to an installation error. CONSTITUTION: A location of a reference mark, which is inscribed on a transfer table(100), is measured. The transfer table is transferred and an installation error of an alignment system(140) is obtained. The transfer table is transferred to a changed direction as much as an obtained installation error. A coordinate location of the reference mark either before or after transferring is obtained. A system variable of the alignment system is determined.
