A method for setting a test probe, - or measuring position of a sensor operating without contact

摘要

A method for setting a test probe, - or measuring position of an optical sensor (26) by means of a testing device (16) by means of at least a defined test - and the measurement task, for the control of at least one optical and / or geometrical feature (12) of an object (14), wherein the test - or measuring position by a measurement point (mp) and a measurement vector (mv) based on a surface of the object (14) is defined, wherein said object (14) by sighting of object points are (op1.. op5) by means of a laser beam, - distance sensor (24) and to a common reference - coordinate system calibrated laser beam (28) and a the measuring point (mp) is straight or having a the measuring point (mp) having a surface section to the alignment of the laser beam (28) is determined, characterized in that the laser beam (28) of the laser - distance sensor (24), as well as an optical axis of action (30) of the optical sensor (28), based on a robot hand - coordinate system (rm - ks) than the common reference - coordinate system of the robot (16) as a testing device is calibrated with respect to the direction and orientation, that the calibrated laser beam (28) on the measuring point (mp) and directed on the basis of the defined test - and measuring tasks by means of the testing device (16) based on the straight line or the surface section for the definition of the messvektos (mv) in a defined distance from and a defined angle is aligned, and in that the on the common reference coordinate system - calibrated optical axis of action (30) by rotating or pivoting of the optical sensor (26) by means of the robot hand in the by means of the laser beam (28) at a distance and angle defined measurement vector (mv) for adjusting the test - or measurement position, the method is.
