Abstract
A device for measuring and calculating the geometrical parameters of an object includes a basic body, a movable and rotatable supporting apparatus for the object, two movable optical area measuring sensors, two illuminating devices allocated to the area measuring sensors, displacement and angle detectors allocated to the supporting apparatus and to the movable optical area measuring sensors, a monitor which is coupled to the area measuring sensors, a computer coupled to the displacement and angle detectors and to the optical area measurement sensors or the monitor, which computer includes a data input device and controllable displacement and rotation devices for the supporting apparatus as well as area measuring sensors being aligned at a right angle to each other and at a right angle or parallel to the axis of rotation of the supporting apparatus. A first area measuring sensor is arranged as a transmitted light measuring sensor and is arranged on a first slide which is movable perpendicularly to the axis of rotation of the supporting apparatus. A second area measurement sensor is arranged as an incident light measuring sensor and is arranged on the second movable slide. The second…
