In recent years, investigating moon is once again drawing attentions of several countries. In Japan, an image-based autonomous navigation method is studied for a moon investigating project by the small lunar lander. The purpose of this paper is to propose a safe landing areas detection method for lunar environmental suitability that uses brightness values and to propose a landing point determination algorithm in a limited calculating area for the actual lunar lander. In addition, we study acceleration of the processing speed for hardware implementation and robustness of the proposed method.
