According to an embodiment, an image processing device includes: a first acquiring unit, a second acquiring unit, a first setting unit, a second setting unit, a first calculating unit, and a second calculating unit. The first acquiring unit acquires a plurality of captured images by imaging a target object from a plurality of positions. The second acquiring unit acquires a provisional three-dimensional position and a provisional size. The first setting unit sets at least one search candidate point near the provisional three-dimensional position. The second setting unit sets a search window for each projection position where the search candidate point is projected, the search window having a size. The first calculating unit calculates an evaluation value that represents whether or not the target object is included inside the search window. The second calculating unit calculates a three-dimensional position of the target object based on the evaluation value.
