Abstract
Mobile robots can be controlled smoothly using forward course situation in the future. The course situation is analyzed in detail through the images obtained by the cmos image sensor or something like that. In this study, the quantity of the information recognized by image processing is important and the method to make the course of a mobile robot to the target point using the visual information in the future is discussed. Fundamental experiments were performed to know the accurate dimensions and the placement of the known rectangular (line segment) target based on the transformed images of it taken by a cmos image sensor.
