Sažetak
The use of vision systems in motion control applications puts hard real-time constrains in image processing. However, constantly increasing performances and decreasing prices of vision hardware make vision measuring systems concurrent to other measureing systems in these applications, where vison systems can be used to precisely measure number of variables such as length, angle, position, orientation, etc. The main advantage of a vision measuring system in these applications is tis non-contact measurement principle, which is important in cases when it is difficult to implement contact measurements. Apart from real-time constraints, the biggest problem that limits the applications of a macine vision system is its robustness to the noise present in the image as well as to the scene disturbances caused by background and foreground objects and to the non-ideal illumination conditions. A simple, computationally efficient and robust machine vision measuring system is described, which is suitable for real-time angle measurement. Its behavior is experimentally tested on a ball and beam bemchmark process, where high quality measurement of the beam angle is achieved even in non-ideal lighting condition and also whe no white background is used. Implemented vision system is used for feedback control of the ball and beam.
