ABSTRACT:
A position determination system comprises a first measuring apparatus and a second measuring apparatus. The first measuring apparatus includes a first sensing device having a sensing field for obtaining positional data of a first testing target, a calibration target rigidly linked to the first sensing device, wherein the positional relationship between the first sensing device and the calibration target is known. The system has a repositioning mechanism for repositioning the sensing field of the first sensing device. The second measuring apparatus includes a second sensing device having a sensing field for obtaining positional data of a second testing target, a calibration sensing device rigidly linked to the second sensing device for obtaining positional data of the calibration target, wherein the positional relationship between the second sensing device and the calibration sensing device is known, and a repositioning mechanism for repositioning the sensing field of the second sensing device. Depending on different needs, the repositioning mechanism readjust the viewing fields of the sensing devices such that the testing targets are properly within the sensing fields of the sensing devices.
