Abstract
Although the technique of performing 3-dimensional measurement of circumference environment had been proposed using the optical flow of a certain time obtained by Active Vision, it was difficult to perform reliable environmental recognition because of the error vector contained in optical flow. In consideration of the hysteresis of optical flow until it results current state from the past, the influence of error vector is mitigated and by using the dynamics of a neural circuits, aims at the system of environmental recognition configuration which can detect the move direction and the improvement in reliability of position detection a still object, or a moving object.
