In recent years, many researchers try to observe the state of the global environment from marine information. In this paper, we introduce the recording system of underwater environment. By using this system, we want to observe the change of global environment from the coral bleaching. Especially, we propose the generation method of marine tag in order to measure the 3D position of robot which is used...
To maintain the safety operation for the crane track, it is important to measure the high accurate three-dimensional position of a crane hook. However, it is not easy to obtain the position information of the swinging crane hook by using sensors. In this paper, we introduce the measurement method of three-dimensional position of the moving crane hook based on the image data obtained by one single...
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...
