In this paper, we propose a method to estimate a robot position and orientation in a room by using a map of color histograms. The map of color histograms is a distribution map of colors measured by a mobile robot in multiple directions at various points. The size of the map should be strongly compressed because the memory capacity of the robot is restricted. Thus, the histograms are converted by the discrete cosine transform, and their high-frequency components are cut. Then, residual low-frequency components are stored in the map of color histograms. Robot localization is performed by matching between the histogram of an obtained image and reconstructed histograms out of the map by means of histogram intersection. We also introduce a series of estimations with the aid of odometry data, which leads to accuracy improvement.
