Title:
METHOD AND APPARATUS FOR COMPENSATING MEASUREMENT ERROR IN MEASURING ROBOT
Document Type and Number:
Japanese Patent JP3032158
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To compensate for the measurement error caused by an external trouble action surely by detecting acceleration at a scanning section and an object to be measured, calculating a correction data indicative of relative movement and correcting the measurement.
SOLUTION: A measuring/scanning section is provided at the end of an arm 20 and a measuring sensor 28 scans an object 100 along a predetermined line. A path detector is provided at the scanning section in order to convert the deflection of sensor 28 accurately into a measurement. Acceleration detectors 21, 26 and also provided in order to detect acceleration acting on a head. Measurement of acceleration is fed to an A/D converter 31 which then delivers a digital data to an evaluation computer 33. The computer 33 calculates undesired relative movement at the scanning section with respect to the object 100 caused by an undesired oscillation and other trouble actions. A correction data thus calculated is removed from measurement data at the scanning section and the measurement error based on the undesired movement is corrected.
