To provide a movement distance measurement system which can specify a movement distance using image data under such a situation that it is difficult to acquire position information by a GPS, and an underwater robot including the movement distance measurement system.SOLUTION: A movement distance measurement system for measuring a distance of movement of a mobile machine body including a first imaging device 13 and a second imaging device 14 that can simultaneously image the same reference object comprises: first distance specification means 16 which specifies the distance from the mobile machine body to the reference object as the first distance by imaging the reference object by the first and second imaging devices at the first point; second distance specification means 16 which specifies the distance from the mobile machine body to the reference object as the second distance by imaging the reference object that moves to the second point different from the first point by the first and second imaging devices; and movement distance specification means 16 which specifies the movement distance of the mobile machine body from the difference between the first distance and the second distance.SELECTED DRAWING: Figure 2

    【課題】GPSによる置情報の取得が困難な状況下で、画像データを用いて移動距離を特定可能とする移動距離計測システム、及びこの移動距離計測システムを備えた水中ロボットを提供する。【解決手段】同一の基準物体を同時に撮影可能とした第1の撮像装置13と第2の撮像装置14とを備えた移動機体が移動した距離を計測する移動距離計測システムであって、第1の地点で基準物体を第1と第2の撮像装置で撮影して移動機体から基準物体までの距離を第1の距離として特定する第1距離特定手段16と、移動機体が第1の地点と異なる第2の地点まで移動して基準物体を第1と第2の撮像装置で撮影して移動機体から基準物体までの距離を第2の距離として特定する第2距離特定手段16と、第1の距離と第2の距離との差から移動機体の移動距離を特定する移動距離特定手段16とを有する。【選択図】図2
