PROBLEM TO BE SOLVED: To improve detection accuracy of objects.SOLUTION: In a normal state where an own vehicle 501 having a laser radar device 11 loaded is indicated in a top row of a Fig. 16, an irradiation range of laser light is set to a monitor area Z11 and thus, an object 551 can be appropriately detected. However, when a concave part 542 is climbed over by a front wheel 501a as shown in a middle row of the Fig. 16, the irradiation range thereof is set to a monitor area Z21, and thus, an object 561 such as a signboard and the like not to be detected is wrongly detected. Further, when a rear wheel 501b climbs over the concave part 542, the irradiation range thereof is set to a monitor area Z22, and thus, an object 562 such as a road stud and the like not to be detected is wrongly detected. Accordingly, the laser radar device 11 is configured to halt object detection processing when amplitude of oscillation in a vertical direction accompanied by a movement of the own vehicle 501 is higher than a prescribed threshold and is in a state as shown in the middle row of the Fig. 16 or a bottom row thereof. The present invention can be applied to, for example, a vehicle laser radar device.SELECTED DRAWING: Figure 16

    【課題】物体の検出精度を向上させる。【解決手段】レーザレーダ装置11を搭載した自車両501が図16の上段で示される通常状態においては、監視領域Z11に設定されているので、物体551を適切に検出することができるが、図16の中段で示されるように、凸部542を前輪501aで乗り越える際には監視領域Z21となり、検出すべきでない看板などの物体561が誤検出される。また、後輪501bが凸部542を乗り越える際、監視領域Z22となり、検出すべきでない道路鋲などの物体562が誤検出される。そこで、レーザレーダ装置11は、自車両501の移動に伴った上下方向の振動の振幅が所定の閾値よりも高く、図16の中段または下段で示される状態のとき、物体検出処理を停止する。本発明は、例えば、車両用のレーザレーダ装置に適用できる。【選択図】図16
