On the Fast Lane
Machine vision interface standards and standards in general usually have pros and cons - it is rare to find a technology that ticks all the boxes. CameraLink is simple, relatively fast, but suffers from restricted cable lengths and ...

Image Processing Basics: Camera Models
Applications of image processing in robotics or 3D-metrology often call for the determination of coordinates for points in real space, the so-called world-coordinates, from the data in the image file. The corresponding calculations are ...

Image Processing Basics: The Background
Image processing in industrial applications often is much simplified when the lighting device provides an image with a homogeneous background. Such a situation allows for robust, stable segmentation of foreground and background. This ...
