The purpose of this paper is to measure the working radius of a crane truck by using vision systems. Then, we introduce the observation device which is equipped with a CCD camera, a laser range finder and two AC servo motors. Further, we propose new algorithm for the mark recognition and then construct PID control system with an extended Kalman filter in order to realize the system without the time...
In this paper, we develop the observation device which measures the working radius of a crane. To realize the measurement, the observation device has the CCD camera and the laser range finder, and the specific mark is attached to a crane. Then, we propose methods for the object recognition and the tracking control. As for the tracking control, to realize the control system without time delay, we construct...
This paper introduces tracking control system with visual feedback to a moving target using a measurement device we developed. In order to recognize the moving object, we use two algorithm, one is the cross-shape mark algorithm and the other is orientation code matching algorithm. Then, the measurement device consists of the PID control system with extended Kalman filter in order to decrease the time...
