To prevent distance information from becoming discontinuous in a portion where angles of view overlap each other when constituting a TOF camera with a wide angle of view.SOLUTION: A distance measuring device comprises: a plurality of TOF cameras that are arranged such that the angles of view overlap each other; and a control unit that corrects distance information acquired by each of the plurality of TOF cameras based on reference distance information in an angle-of-view overlapping area.SELECTED DRAWING: Figure 1 【課題】画角の広いＴＯＦカメラを構成する場合に画角の重なり合う部分で距離情報が不連続にならないようにする。【解決手段】測距装置は、互いの画角が重複するように配置された複数のＴＯＦカメラと、複数のＴＯＦカメラの各々が取得した距離情報を、画角重複領域での基準距離情報に基づいて補正する制御部と、を備える。【選択図】図１
