Zusammenfassung: | To provide a technology capable of accurately ranging even when using an optical ranging device for a long time or outdoors.SOLUTION: An optical ranging device 100 includes: a light-emitting optical system 20 which emits pattern light having an irradiation area and a non-irradiation area; a light-receiving sensor 40 having an array-like light-receiving element 41; a light-receiving optical system 30 which receives reflection light of the pattern light from an object, enlarges a portion of the reflection light corresponding to the irradiation area larger than one light-receiving element to be incident on the light-receiving sensor 40; a distance measurement section 55 which measures a distance to the object on the basis of an output from the light-receiving sensor; and a position adjustment section 33 which adjusts a position of at least a part of the light-emitting optical system and the light-receiving optical system on the basis of the output from the light-receiving sensor.SELECTED DRAWING: Figure 1
【課題】光測距装置において、長期間使用した場合や屋外で使用する場合においても精度よく測距を行うことのできる技術を提供する。【解決手段】光測距装置100は、照射領域および非照射領域を有するパターン光を投光する発光光学系20と、アレイ状の受光素子41を有する受光センサ40と、対象物からパターン光の反射光を受光し、反射光のうちの照射領域に対応する部分を、1つの受光素子よりも大きく拡大して受光センサ40に入射させる受光光学系30と、受光センサからの出力に基づいて対象物までの距離を測定する距離測定部55と、受光センサからの出力に基づいて、発光光学系および受光光学系の少なくとも一部の位置調整を行う位置調整部33と、を備える。【選択図】図1 |
