Abstract:
A system for determining spatial coordinates of points, wherein the system involves a fixed array of a network of control points, comprising:a manually or mechanically manipulatable measuring probe containing at least one camera and wherein the measuring probe is designed for physical contact with a measuring point on an object which is to be measured via a fixedly mounted contact unit projecting from the measuring probe, which has a known, defined position in the coordinate system of the measuring probe; and a system unit which computes the position of contact unit relative to a coordinate system defined by said control points on the basis of the measuring probe's image making of the control points, and the known position of the contact unit in the coordinate system of the measuring probe, wherein the measuring probe has a contact sensor which is functionally connected to the contact unit for registering mechanical contact between the contact unit and the object which is to be measured at the measuring point, the contact sensor on said registration causing automatic position measurement.
