Abstract
A positioning device for a measuring machine wherein a measuring head is movable in a three-dimensional space with respect to a first reference system, and supports a visual sensor having a television camera and a source of a laser beam. The device displays on a monitor the two-dimensional image picked up by the camera and on which is positionable a pointer movable by manual control to select a point of interest in the displayed two-dimensional image. The device moves the measuring head automatically into a position in which the origin of a second reference system, proper to the visual sensor and having two coordinate axes in the two-dimensional image plane, is located at a point, in the three-dimensional space, corresponding to the point of interest selected on the two-dimensional image.
