Abstract
A function of image recognition is indispensable to an intelligent robot, which can coexist with a human being. Furthermore, the intelligent robot needs to understand the environment of their action range by getting information of characters and maps on signboards in order to act autonomously. In this research, a method using the Color Distance to extract the ground of signboard from one piece of picture by robot's camera and revising the distortion by virtual movement of a viewpoint is described. It is shown that character strings on the signboard is recognized by an optical character reader after revising the distortion. © Springer-Verlag Berlin Heidelberg 2005.
