Title (EN) DISTANCE MEASUREMENT DEVICE AND MOVING BODY
(FR) DISPOSITIF DE MESURE DE DISTANCE ET CORPS MOBILE
(JA) 距離測定装置、および移動体
Abstract:
(EN) [Solution] This distance measurement device is configured to be provided with: a light projection unit that includes a light emission unit and that performs rotary scanning using projection light; a light reception unit; a distance measurement unit that measures the distance to an object to be measured, on the basis of emission of the projection light and light reception performed by the light reception unit; and an emission control unit that controls the light emission unit, wherein, for every n cycles (n is an integer of 1 or greater) of the rotary scanning, the emission control unit changes the output level of the projection light and the emission interval of the projection light, while keeping the average power of the projection light fixed.
(FR) La solution selon l'invention porte sur un dispositif de mesure de distance qui est configuré pour être pourvu de : une unité de projection de lumière qui comprend une unité d'émission de lumière et qui effectue un balayage rotatif à l'aide d'une lumière de projection ; une unité de réception de lumière ; une unité de mesure de distance qui mesure la distance jusqu'à un objet à mesurer, sur la base de l'émission de la lumière de projection et de la réception de lumière effectuée par l'unité de réception de lumière ; et une unité de commande d'émission qui commande l'unité d'émission de lumière, dans laquelle, tous les n cycles (n est un entier supérieur ou égal à 1) du balayage rotatif, l'unité de commande d'émission change le niveau de sortie de la lumière de projection et l'intervalle d'émission de la lumière de projection, tout en maintenant fixe la puissance moyenne de la lumière de projection.
(JA) 【解決手段】発光部を含んで投射光による回転走査を行う投光部と、受光部と、前記投射光の出射と前記受光部による受光とに基づいて計測対象物までの距離を計測する距離計測部と、前記発光部を制御する発光制御部と、を備え、前記発光制御部は、前記回転走査のn周期(nは1以上の整数)ごとに、前記投射光の平均パワーを一定として前記投射光の出力レベルおよび前記投射光の発光間隔を変化させる距離測定装置としている。
