| description | To provide an information processing device capable of preferably determining the existence of noise at a measurement point at which a distance is measured, a control method, a program and a storage medium storing the program.SOLUTION: A spatially stable point detection block 74 gives a second effective point flag F2 showing effectiveness to a measurement point at which other measurement points exist within a candidate determination threshold dDth1 about a plurality of measurement points acquired in each frame and each showing a distance from a reference point. Then, the spatially stable point detection block 74 performs grouping in each measurement point group in which a distance between measurement points is within a block determination distance threshold dDth2 to measurement points to which the second effective point flag F2 showing effectiveness is given. Then, the spatially stable point detection block 74 determines whether or not the measurement point with the second effective point flag F2 given thereto is a noise generation point in each group on the basis of a group measurement point number Ng being the number of measurement points in each group.SELECTED DRAWING: Figure 1
【課題】距離が計測された計測点においてノイズの存在を好適に判定することが可能な情報処理装置、制御方法、プログラム及びプログラムを記憶した記憶媒体を提供する。【解決手段】空間的安定点検出ブロック７４は、フレーム毎に取得された、それぞれが基準点からの距離を示す複数の計測点について、候補判定閾値ｄＤｔｈ１以内となる他の計測点が存在する計測点に対し、有効であることを示す第２有効点フラグＦ２を付与する。そして、空間的安定点検出ブロック７４は、有効であることを示す第２有効点フラグＦ２が付与された計測点に対し、計測点間の距離が塊判定距離閾値ｄＤｔｈ２以内となる計測点群毎にグループ分けを行う。そして、空間的安定点検出ブロック７４は、グループ毎の計測点の個数であるグループ計測点数Ｎｇに基づき、第２有効点フラグＦ２が付与された計測点がノイズ発生点であるか否かの判定をグループ毎に行う。【選択図】図１ |
