Non-contact optical sensors – Image processing

With the image processing sensor, the illuminated measuring object is imaged onto a matrix camera using a lens. The measurement points are calculated in an evaluation computer with corresponding image processing software. Werth contour image processing recognises not only points, but also contiguous contours in the image. This enables specific contour selection for reliable edge detection and rigid scanning. Contour, image and element filters ensure reliable measurements.
In the patented Raster Scanning HD mode, many single images (yellow squares) are captured while moving along a predefined path (blue line) and merged to form a high-resolution image (blue rectangle). All contours (red) in the measurement window (green) are captured automatically.
