To provide a position determination method which allows for detecting the position of any point on a target.SOLUTION: A position determination method provided herein comprises extracting a boundary between point clouds with different brightness according to a brightness pattern of reflected light when an object is irradiated with light from a light source of a light detection and ranging device, allocating a line segment or curve to the boundary, and determining the target position based on the line segment or curve.SELECTED DRAWING: Figure 1 【課題】ターゲットにおける任意の点の位置を検出することができる位置特定方法を提供する。【解決手段】位置特定方法は、光検知測距装置の光源から対象物へ光を照射したときの反射光の輝度パターンに基づいて、輝度が異なる点群の境界を抽出するステップと、境界に線分または曲線を割り当てるステップと、線分または前記曲線に基づいて目標位置を特定するステップと、を有する。【選択図】図１
