Abstract
One or more non-contacting gauging sensors are calibrated to a common external coordinate system by providing each sensor to be calibrated with a target which can be simultaneously viewed by the sensor and an external measuring system for determining coordinates of the target in terms of the external coordinate system and in terms of the sensor coordinate system. With the resulting spatial coordinates of the target expressed in both frames of reference, transform matrix coefficients can be calculated, for example with a programmable computer, to calibrate each sensor to the preselected common external coordinate system.
