Color image processing system BV

The basic equipment of most optical and multi-sensor coordinate measuring machines Compared to other sensors, measurement with image processing usually leads to much shorter measurement times and can therefore be used for a wide variety of applications. Many measurement points are captured quickly or even simultaneously. • Fast detection of multiple geometric elements and freeforms in the measuring window through intelligent contour image processing • Reliable edge detection even with minimal contrast thanks to image, contour and element filters • Patented raster scanning HD generates an overall image of the workpiece while the device axes are moving, independent of the sensor's field of view • Automatic adjustment of light intensity for changing surface properties and colours • Standardisation of illumination characteristics for easy exchange of control files from different optical coordinate measuring machines possible • Special solutions are offered by Werth Zoom and MultiRing® with variable working distance and illumination angle Sensor principle Optical-lateral Measuring range Field of view "in the image" 0.065 mm x 0.05 mm to 225 mm x 190 mm Accuracy Permissible probing error up to 0.2 µm Functionality In the camera a) an image of the measuring object c) is created with the aid of the imaging optics b), here with transmitted light illumination d).
