- Summary:
- 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. Basis for the mathematical processing is the photogrammetry. So, the spatial position or the three-dimensional shape and form are determinable.The scanners are designed modularly. They enable the serial and parallel interconnection of various scanner modules to a matrix. The measurement of large areas in short time intervals will be possible. Measuring and processing of the point cloud will be realized much faster and with higher accuracy. The use of these methods and technologies in the context of modular design of the scanner, and their combination in a matrix arrangement are the outstanding USP for this innovation. The idea was proofed and patented as "Scanning system with stereo camera set" (e.g. US7639372B2)
