OPTICAL RANGING DEVICE

To provide an optical ranging device capable of accurately detecting an object by reducing influence of a pseudo object.SOLUTION: An optical ranging device 200 has: a light emitting unit 40 which emits emitted light DL; a light receiving unit 60 which has a light receiving pixel for receiving incident light, and outputs a detection signal corresponding to received light intensity of the incident light received by the light receiving pixel; and a control device 100 which acquires a detection signal corresponding to the received intensity of reflected light from the light receiving unit 60 which receives reflected light RL corresponding to emitted light reflected by an object OB as the incident light, and detects distance to an object by using the detection signal corresponding to the received light intensity of the reflected light. The control device 100 may remove a detection result of a second object OB, when a first object OB and the second object OB located at a distance which is N times the distance to the first object OB (N is a natural number of 2 or more) on an extension of the straight line connecting the optical ranging device 200 are detected, and it is determined that the second object OB is a pseudo object corresponding to the first object OB.SELECTED DRAWING: Figure 1 【課題】疑似物体の影響を低減して、物標を正確に検出することができる光測距装置を提供する。【解決手段】光測距装置２００は、出射光ＤＬを出射する発光部４０と、入射光を受光するための受光画素を有し、受光画素に受光した入射光の受光強度に対応する検出信号を出力する受光部６０と、物体ＯＢによって反射された出射光に対応する反射光ＲＬを入射光として受光した受光部６０から、反射光の受光強度に対応する検出信号を取得し、反射光の受光強度に対応する検出信号を用いて物体までの距離を検出する制御装置１００と、を備える。制御装置１００は、第一物体ＯＢと、光測距装置２００と第一物体ＯＢとを結ぶ直線の延長上であって第一物体ＯＢまでの距離のＮ倍（Ｎは２以上の自然数）の距離に位置する第二物体ＯＢとが検出され、かつ、第二物体ＯＢが第一物体ＯＢに対応する疑似物体であると判定した場合に、第二物体ＯＢの検出結果を除去してよい。【選択図】図１
