Device and Method For Determining the Change of Position of a 3D Measuring Head

摘要

The invention relates to a device for determining the change of position of a 3D measuring head, comprising a 3D measuring head; at least one sensor device, connected to the 3D measuring head, to detect a respective position-dependent measured quantity; and an evaluating device for determining a change of position of the 3D measuring head at a final position relative to a starting position from the at least one detected measured quantity; wherein the change of position includes a displacement in space and a rotation in space. The invention further relates to a corresponding method.

1. Device for determining the change of position of a 3D measuring head, comprising:
a 3D measuring head; at least one sensor device, integrated in the 3D measuring head, to detect a respective position-dependent measured quantity, the position-dependent measured quantity comprising a spatially inhomogeneous field; and an evaluating device for determining a change of position of the 3D measuring head at a final position relative to a starting position from the at least one detected measured quantity; wherein the change of position includes a displacement in space and a rotation in space; and wherein the change of position in space can be determined with respect to three linearly independent axes of displacement of the internal coordinate system of the starting position or the final position, and the rotation in space can be determined with respect to three linearly independent axes of rotation of the internal coordinate system of the starting position or the final position.
