This work describes a real-time method, based on motion energy detection, for detecting and tracking moving object in the consecutive image sequences. The motion of moving objects is detected by taking the difference of the two consecutive image frames. In addition an edge information of the current image is utilized in order to further increase the accuracy of detection. We can track the moving objects continuously by detecting the motion of objects from the sequence of image frames. A prototype system has been implemented using a TI TMS320C6201 EVM fixed-point DSP board, which can successfully track a moving human in real-time.

A two-dimensional moving target is necessarily captured by a 5 dot robot system using a robot vision technique. Here, a robot vision system with a visual skill so that it can take information for a moving target or object, specially two dimensionally moving, is introduced and its algorithm and control strategy are presented associated with it. The tracking algorithm is proposed and its performance is verified by experiment. The camera first captures the object, then it captures again after certain second. The position difference generates the horizontal and vertical velocities of the moving target, hence the final destination is estimated at gripping line. At the same time, the robot s...

This paper presents a coupling scheme of LSM(Level Set Method) and Poisson's equation to analyze the dynamic performance of electromagnetic system with moving parts. Remeshing process is necessary to analyze the dynamics of moving object using finite element method. LSM is useful for analysis of moving objects or propagating models in time varying system. In this paper, we proposed the material setting technique of mover using level set function. To validate the algorithm, we adopted the simple hinged electromagnet model with moving arm. The results of simulation are reasonable as expect.

In this paper, we propose a predictive system for the avoidance of the moving obstacle. In the dynamic environment, robots should travel to the target point without collision with the moving obstacle. For this, we need the prediction of the position and velocity of the moving obstacle. So, we use the Kalman filer algorithm for the prediction. And for the application of the Kalman filter algorithm about the real time travel, we obtain the position of the obstacle which has the future time using Fuzzy system. Through the computer simulation studies, we show the effectiveness of the proposed navigational algorithm for autonomous mobile robots.

This paper proposes trajectory tracking of the moving object based on one camera vision system. And, this system proposes a method which robot manipulator grips moving object and predicts coordinate of moving objcet. The trajectory tracking and position coordinate are computed by vision data acquired to camera. Robot manipulator tracks and grips moving object by vision data. The proposed vision systems use a algorithm to do real-time processing.

자동차, 보행자 등 다양한 교통 요소와 도로를 공유하는 자전거를 이용하는 이용자의 수가 증가함에 따라 자전거 관련 사고도 증가하고 있다. 특히 복잡한 교통 환경에서 자전거 이용자는 보행자 등 이동 객체를 사전에 인지하지 못해 발생하는 자전거 사고도 자전거 사고의 많은 부분을 차지하고 있다. 본 논문에서는 자동차간 네트워크에 자전거를 연결하여 객체의 이동 방향 등의 정보를 획득함으로써 자전거 사고 감소 또는 방지하기 위한 자전거 충돌 회피 시스템 구조를 제안한다. 이 구조에서는 자동차 등의 교통 요소가 이동 객체를 인지하고 이 객체의 위치와 이동 방향을 네트워크를 통해 전송하며, 이 정보를 수신한 자전거의 시스템은 자전거 이용자에세 경고를 하여 충돌 사고를 방지할 수 있다.

This paper describes vibration control of a suspended system using wave absorption method. A moving multiple-pendulum system and a moving wire-and-load system are treated. The wire-and-load system is extended to a model crane system that has a motor system to roll up and down the suspended mass like a real crane. The same program with different parameter values controls these three systems. Both numerical simulation and experiment have been conducted, and the present control method has shown to be quite effective.

In this paper, an active vibration control of a translating steel strip in a zinc galvanizing line is investigated. The control objectives in the galvanizing line are to improve the uniformity of the zinc deposit on the strip surfaces and to reduce the zinc consumption. The translating steel strip is modeled as a moving belt equation by using Hamilton’s principle for systems with moving mass. The total mechanical energy of the strip is considered to be a Lyapunov function candidate. A nonlinear boundary control law that assures the exponential stability of the closed loop system is derived. The existence of a closed-loop solution is shown by proving that the closed-loop dynamics is dissipative. Simulation results are provided.
