Abstract

A device for position determination of measuring points of a measuring object comprises a measuring means for determining the position of the measuring points relative to the position of the measuring means and a reference measuring means for determining the position of the measuring means relative to a reference system. The reference measuring means comprises a measuring arm or a robot arm, the proximal end of which is fixed with respect to the reference system, and the measuring means comprises an optical sensor means disposed at the distal end of the measuring arm or robot arm. The optical sensor means comprises at least two single or multiple image sensors which record images of at least part of the measuring object. A processing means determines the position of the measuring points of the measuring object from the recorded images. The processing of the recorded images is effected at least as rapidly as the recording frequency of the single and multiple image sensors, in real time (real time processing).

Dependent claims

A device for position determination of measuring points of a measuring object, the device comprising:

a stationary support defining a reference system;
a measuring arm having a proximal end mounted to said stationary support and fixed with respect to said reference system;
reference measuring means for detecting, at a reference measuring frequency, a position of a distal end of said measuring arm relative to said reference system;
at least two image sensors mounted to said distal end of said measuring arm, said image sensors generating recorded images of the measuring object at a recording frequency for detecting positions of the measuring points relative to said image sensors and relative to said distal end of said measuring arm;
and
a processing means connected to said reference measuring means and connected to said image sensors for determining, at a processing frequency, positions of the measuring points relative to said reference system from said recorded images, wherein said processing frequency is greater than or equal to said recording frequency and said reference measuring frequency, for real time processing.
