Abstract:
1. A system for measurement of spatial coordinates, the system comprising a probing tool, a main measuring unit, and at least two targets located in known positions relative to said distance measuring device, said probing tool disconnected from said measuring unit, wherein said probing tool comprises: a) a reflective object element, b) an observation mechanism located in a known position and orientation relative to said reflective object element and capable of observing said at least two targets, c) an offset mechanism connected to said reflective object element for measuring points other than the center of said reflective object element by using a know orientation and position of said reflective object element, wherein said offset mechanism is connected with said reflective object element and with said observation mechanism via a mechanism constructed for relative rotation, said mechanism including a mechanism constructed and adapted to measure said rotation; and wherein said main measuring unit comprises: d) a distance measuring device constructed and adapted to measure a distance from said device to said reflective object element; and e) a direction determining mechanism constructed and adapted to determine a direction of a measuring beam; whereby the orientation of said reflective object element can be determined from observations of said targets by said observation mechanism, using the direction of the measuring beam and the distance from the measuring device to the reflective object element.
