  • Device and method for non-contact recording of spatial coordinates of a surface
    Patent number: 8791997
    Abstract: A device and a method for non-contact recording of spatial coordinates of a surface includes a sensor head and a controller connected to the sensor head. The sensor head is designed as a portable hand-held device, a projector and two cameras. The controller is also designed as a portable device, with an electrochemical energy source housed in the controller or in the sensor head for power supply to the sensor head and the controller and no cable connection of the sensor head or the controller is provided to further stationary components of the device.

  • Method and device for determining the spatial co-ordinates of an object
    Patent number: 7136170
    Abstract: The invention relates to a method for determining the spatial co-ordinates of an object, whereby the object is illuminated with patterns of light from at least two directions by means of a projection device. A calibrating camera and at least one measuring camera at least partially record the patterns of light projected onto the object, the calibrating camera being fixed in relation to the object. The projection device is calibrated by means of at least four phase measuring values, the measuring camera is calibrated using at least two phase measuring values, the three-dimensional co-ordinates of the object are calculated using at least one phase measuring value. The projection device and the measuring camera are thus transferred together into the desired positions.

  • Device for non-contact measurement of the surface of a three dimensional object
    Patent number: 6055056
    Abstract: This invention concerns a device for non-contact measurement of the surface of a three dimensional object in a measuring chamber with a projection device which projects a strip structure on the surface of an object, an observing device for recording the strip structure at measuring points on the surface of the object, a device for moving the object together with the observing device around a first axis of rotation, and an evaluation unit for determining the co-ordinates of the measuring points using the phase values of the strip structure in a predetermined co-ordinate system. A device (8) for moving the object about at least a second axis of rotation (D2) independent of the first axis of rotation (D1) and a calibration unit are provided, where the calibration unit (10) can determine the position of the second rotational axis (D2) in the predetermined co-ordinate system.
