In this research, we study that information acquisition from guide sign in the indoor environment, such as airport, building, and station premises. The information helps robot to understand the meanings of environment, and to decide the path to the destination. Generally, guide sign hanged up on the ceiling consists of an arrow and some words. Our strategy is that the robot detects only the arrow, and the words around it. In the future, we will make a mobile robot to create topological map. In this paper, we try to use machine learning for the detection, assumed a guide sign place, and estimation examines indicating direction of guide sign.
