Achieving and sustaining high levels of quality is an essential prerequisite for successful and sustainable development. The requirement for the description of the existing quality levels are measurement parameters and comparative values for defining the state of the art. The quality of products is defined by measurements determining information for comparing with the planned parameters. The measurement results are used to determine absolutely and relatively the achieved quality. Products change shape and form within the whole product lifecycle. The more accurate and safe the measurement of form and shape become, the better the product quality can be defined. The methods of 3D-measurement are divided into contact (mechanical) and non-contact (optical) using CMMs, 3D scanners and 3D cameras. Advanced methods exploit e.g. the stereo photography. Therefore, a scanner technology has been developed based on 3D surface stereo photography.
