The present invention addresses the problem of providing a position estimation system for positioning a forklift using an image by reducing the influence of a gantry or the like reflected on the image. A position estimation system according to the present invention, which estimates the position of a forklift equipped with a camera, is provided with: a position estimation unit that estimates the position of the forklift on the basis of features included in an image captured by the camera; and a reflection determination unit that calculates a reflection range indicating a range in which the gantry is reflected in the image on the basis of the position of the gantry provided in the forklift in the height direction, and determines that the position estimation by the position estimation unit is stopped when the calculated reflection range exceeds an allowable range.

    技术问题本发明提供一种关于使用了图像的叉车的定位,降低门架等映入到图像的影响来进行定位的位置推定系统。解决方案本发明的位置推定系统是对具备摄像机的叉车的位置进行推定的位置推定系统,具备:位置推定部,基于由所述摄像机拍摄到的图像中所包含的特征,对所述叉车的位置进行推定;以及映入判定部,基于所述叉车所具备的门架的高度方向的位置来计算出表示在所述图像中映现所述门架的范围的映入范围,在计算出的所述映入范围超过容许范围的情况下,判定为停止由所述位置推定部进行的所述位置的推定。
