Optical measurement in quality control
For quality assurance purposes, components are tested before they are used. The measured values obtained must be interpreted and compared with predetermined target values. This often requires complex mathematical calculations. If there is no suitable standard software or you want to have full control of the algorithms used, you need to perform the calculations yourself.
Example
Components of a vehicle exhaust system are measured optically by means of laser triangulation for KÜBLER & ESSIG GmbH. From the measured values obtained, the centre point can then be determined for bodies of arbitrary shapes. Using mathematical methods, the calculations can even be performed on a Siemens S7 device driver.
