Optical positioning aid for a distance sensor, distance measuring system and corresponding method

A distance measuring system comprising:

• a distance sensor for measuring a distance between the distance sensor and a measured object;
• and
• an optical positioning aid for the distance sensor for assisting in the positioning of the distance sensor relative to the measured object, comprising:
• a light source for generating a setting light beam, wherein the setting light beam has a wavelength in a visible range and is suitable for generating a light spot on the measured object, and
• a control unit which has a distance input and is communicatively connected to the light source in order to control at least one property of the setting light beam,
• wherein the control unit is designed to evaluate an input value input into the distance input and to influence at least one property of the setting light beam on the basis of a result of the evaluation in such a way that the setting light beam allows conclusions to be drawn about the input value;
• wherein the distance sensor is communicatively connected to the optical positioning aid and inputs an input value that is representative of a measured distance value, into the distance input of the optical positioning aid, and
• wherein the distance sensor is formed by an optical sensor,
• the distance measuring system further comprising an optical coupler that couples a measuring light beam emitted by the distance sensor and the setting light beam to enable a common optical means to direct the measuring light beam and setting light beam to the measured object.
