Abstract PROBLEM TO BE SOLVED: To provide a position indication method with which it is possible to indicate movement to a discretionary position to a self-propelled device.SOLUTION: The position indication method includes the steps of: storing, in a map database 24, map information in which position information relating to the position of a self-propelled cleaner 4 in a travel area and a first feature value calculated from an image photographed at the position are correlated; acquiring an object image in which a first object present at a first position in the travel area is photographed; calculating a second feature value from the object image; extracting map information that includes the first feature value that matches the second feature value from the map database 24; specifying a second position that corresponds to the first position on the basis of the extracted map information; and notifying an indication for moving the self-propelled cleaner 4 to the specified second position.SELECTED DRAWING: Figure 11 【課題】自走式装置に対して任意の位置への移動を指示することができる位置指示方法を提供する。【解決手段】位置指示方法は、自走式掃除機4の走行領域における位置に関する位置情報と、当該位置において撮影された画像から算出された第1の特徴量とが対応付けられた地図情報を地図データベース24に記憶させるステップと、走行領域における第1の位置に存在する対象物を撮影した対象物画像を取得するステップと、対象物画像から第2の特徴量を算出するステップと、地図データベース24から第2の特徴量に一致する第1の特徴量を含む地図情報を抽出するステップと、抽出した地図情報に基づいて、第1の位置に対応する第2の位置を特定するステップと、特定した第2の位置に自走式掃除機4を移動させるための指示を通知するステップとを含む。【選択図】図11
