| description | To provide a position estimation system, for positioning of a forklift using an image, configured to perform positioning while reducing the influence of a mast, and the like, reflected in the image.SOLUTION: A position estimation system for estimating a position of a forklift equipped with a camera includes: a position estimation unit configured to estimate a position of the forklift on the basis of a feature included in an image captured by the camera; and a reflection determination unit configured to calculate, on the basis of a position in a height direction of a mast included the forklift, a reflection range indicating a range in which the mast appears in the image and determine to stop the position estimation unit estimating the position unit when the calculated reflection range exceeds an allowable range.SELECTED DRAWING: Figure 1
【課題】画像を用いたフォークリフトの測位に関し、マスト等の画像への映り込みの影響を低減して測位を行う位置推定システムを提供する。【解決手段】位置推定システムは、カメラを備えるフォークリフトの位置を推定する位置推定システムであって、前記カメラによって撮影された画像に含まれる特徴に基づいて、前記フォークリフトの位置を推定する位置推定部と、前記フォークリフトが備えるマストの高さ方向の位置に基づいて、前記画像において前記マストが写る範囲を示す映り込み範囲と、を算出し、算出した前記映り込み範囲が許容範囲を超える場合には、前記位置推定部による前記位置の推定を停止すると判定する映り込み判定部と、を備える。【選択図】図１ |
