Patent ID: 7117109

Claim:
A method for processing measuring data from a measuring system, wherein the method comprises: a) calibrating the measuring system, wherein said calibrating includes: a 1 ) stimulating the measuring system by changing cause variables responsible for systematic measuring errors of the measuring system, and determining corresponding measuring data; and a 2 ) determining effect vectors corresponding to systematic measuring errors from the measuring data obtained in step a 1 ) by using a mathematical method, wherein the effect vectors are based on a mathematical model with which the measuring data is estimated, wherein the mathematical model contains an error term containing an effect vector assigned to a measuring error and a corresponding error contribution; b) measuring, using the measuring system, wherein said measuring includes: b 1 ) obtaining measuring data that corresponds to information concerning a process, while the process is taking place, and that depends on at least two variables; and b 2 ) transforming the measuring data gathered in step b 1 ) to linear components, based on the effect vectors determined in step a 2 ), b 3 ) using a mathematical method that corrects said transformed measuring data from step b 2 ) for said systematic measuring errors; and b 4 ) outputting the corrected transformed measuring data from step b 3 .
