Abstract
The purpose of a system for measuring the location and orientation of an ect is to align one object with another by simultaneously measuring the six degrees of freedom of the objects. The system accomplishes the purpose by employing a linear optical detector array sensor on the first object and a pre-selected target pattern on a second object to measure the six degrees of freedom and converting them to six position measurement via a microprocessor which has suitable algorithms residing in it. The six position measurements (azimuth, elevation, range, pitch, yaw and roll) are displayed for viewing by the operator who, then, manipulates the objects until pre-determined desired values of the six position measurements are obtained, indicating a complete alignment between the objects.
