Coordinate measuring machine having a camera

A coordinate measuring machine for determining at least one spatial coordinate of a measurement point of an object to be measured, comprising:

• a base,
• a probe head comprising a tactile measuring sensor,
• a drive mechanism comprising at least one motor drive, adapted to drive the probe head relative to the base for approaching the measurement point,
• a first range camera having a range image sensor with a sensor array, wherein the range camera is adapted to be directed to a user of the coordinate measuring machine to take a sequence of user range images, and
• a controller comprising a processor and a memory, wherein the controller is adapted to:
• control the drive mechanism by actuating the at least one motor drive,
• determine changes of a current user range image to one or more of preceding user range images,
• identify, based on the changes, at least one movement of the user that corresponds to a predefined command, wherein one or more movements of the user are predefined as a command for one or more actions to be performed, and
• automatically control the coordinate measuring machine on the basis of the command corresponding to the identified movement.

• at least a first range camera having a range image sensor with a sensor array, wherein the first range camera is adapted to be directed to the object for providing a range image of the object, and
• a controller, comprising a processor and a memory, the controller being adapted to control the drive mechanism by actuating the at least one motor drive and to determine the at least one spatial coordinate by determining a drive position of the drive mechanism,
• wherein the first range camera or a second range camera is adapted to be directed to a user of the coordinate measuring machine to take a sequence of user range images,
• wherein the controller is adapted to:
• create a point cloud with the 3D-positions of the target points of the object by using the range pixels of the range image,
• determine changes of a current user range image to one or more of preceding user range images,
• determine, based on the changes, at least one movement of the user that corresponds to a predefined command, wherein one or more movements of the user are predefined as a command for one or more actions to be performed, and
• automatically control the drive mechanism on the basis of the 3D-positions of the target points and/or control the coordinate measuring machine on the basis of the command corresponding to the identified movement.
