Advantages of the digital Vision system:
▪ Robust and fast computing algorithms
▪ Flexible measurement processes
▪ Intuitive graphical user interface
▪ Geometric description of components at the machine
▪ State-of-the-art digital camera hardware
▪ Homogenous illumination of camera field of vision and components
Each C&P head has its own digital component camera.
