Abstract
In this paper, a new zoom and focus mechanism for a high speed-vision is proposed. The mechanism consists of a varifocal lens and two AC servo motors. It is lightweight, and it has good performance to be controlled at high speed. We propose a visual servoing control for the zoom and focus mechanism. As the image features, the area of a target and SML (Sum of Modified Laplacian) are used. The relationships between these features and the joint angles of motors are measured to decide the parameters of control.
