Abstract
A coordinate measuring apparatus carries a video camera 6 and a mechanical probe head 7 having a probe element 8 for contact-measuring the workpiece surface. With the aid of the coordinate measuring apparatus, the locations on the workpiece 9 to be mechanically contacted are driven to under visual control with the aid of the monitor 10 connected to the video camera. For this purpose, the probe element 8 is located in the viewing field of the video camera 6.
Claims15
A method of making coordinate measurements on a workpiece with a coordinate measuring apparatus carrying a video camera and a mechanical probe element for contact measuring the workpiece surface, the method comprising the steps of:
- mounting said probe element on a probe head of the coordinate measuring apparatus;
- changing the position of an articulated joint so as to align the mechanical probe element and the video camera to each other so that the probe element is located in the viewing field of the video camera;
- and,
- driving to the locations on the workpiece to be mechanically contacted with the probe element under visual control with the aid of a monitor connected to the video camera.
A coordinate measuring apparatus for making measurements on a workpiece, the coordinate measuring apparatus comprising:
- a monitor for displaying an image of the workpiece;
- a video camera having a field of view and being connected to said monitor for supplying said image thereto;
- a movable mechanical probe head having a probe changing unit and a probe element being mounted on said probe head via said probe changing unit to obtain measurements of the workpiece and said probe head including means for emitting signals indicative of said measurements;
- computer and control means for processing said signals and for controlling the movement of said probe head relative to the workpiece;
- and,
- an articulated joint connected between said video camera and said mechanical probe for aligning said mechanical probe head and said video camera so as to cause said probe element to be in said field of view.
A coordinate measuring apparatus for making measurements on a workpiece, the coordinate measuring apparatus comprising:
- a monitor for displaying an image of the workpiece;
- a video camera having a field of view and being connected to said monitor for supplying said image thereto;
- a movable mechanical probe head having a probe changing unit and a probe element being mounted on said probe head via said probe changing unit to obtain measurements of the workpiece and said probe head including means for emitting signals indicative of said measurements;
- computer and control means for processing said signals and for controlling the movement of said probe head relative to the workpiece;
- a deflector for deflecting the beam path of said video camera in the direction toward the probe element;
- and,
- a pivot joint connecting said deflector to said video camera for adjusting said beam path of said video camera so as to cause said probe element to be in said field of view.
