Abstract
(EN)
In a laser rangefinder (100) according to the present invention, an optical device (101) projects a scanning grid pattern (60) onto an object by irradiating laser light onto the object, a camera unit (40) photographs the projected image at that time as a photographed scanning grid pattern (70), and a measurement unit (53) measures the distance to the object on the basis of the distance between the lines represented by the photographed scanning grid pattern (70). As a result, even if the rangefinder is mounted onto a small robot, a vehicle, or the like, the distance from the rangefinder to an object can be easily measured.
(FR)
La présente invention porte sur un télémètre à laser (100) dans lequel un dispositif optique (101) projette un motif de grille de balayage (60) sur un objet par rayonnement d'une lumière laser sur l'objet, une unité d'appareil photographique (40) photographie l'image projetée à ce moment sous la forme d'un motif de grille de balayage photographié (70), et une unité de mesure (53) mesure la distance par rapport à l'objet sur la base de la distance entre les lignes représentées par le motif de grille de balayage photographié (70). Par conséquent, même si le télémètre est monté sur un petit robot, un véhicule ou autre, la distance du télémètre à un objet peut être facilement mesurée.

レーザ測距装置(100)では、光学ユニット(101)が、対象物にレーザ光を照射することにより格子走査パターン(60)を対象物に投影し、カメラ部(40)が、そのときの投影像を撮影格子走査パターン(70)として撮影し、計測部(53)が、撮影格子走査パターン(70)が表す線の間隔に基づいて、対象物までの距離を計測する。これにより、例えば自装置を小型ロボットや車両等に搭載した場合であっても、自装置から対象物までの距離を容易に測定することができる。
