Abstract:
(EN) A distance measurement and imaging device having a high signal-to-noise ratio and distance measurement accuracy is provided. The distance measurement and imaging device is provided with: a signal generation unit for generating a light emission signal and a light exposure signal; a light source unit for receiving the light emission signal and irradiating light according to the received light emission signal; an imaging unit for receiving the light exposure signal, carrying out exposure according to the received light exposure signal, and acquiring a reflected light exposure amount; and a calculation unit for calculating distance information on the basis of the exposure amount and outputting the distance information. The imaging unit acquires a first exposure amount corresponding to the exposure during a first emission and exposure period in which the light exposure signal is received and exposure is performed at the same time that the light emission signal is received and a second exposure amount corresponding to the exposure during a second emission and exposure period in which the light exposure signal is received and exposure is performed after a delay time has passed since the reception of the light emission signal. The calculation unit calculates the distance information from the first exposure amount, which is obtained through the variation of the number of light emission signal repetitions in the first emission and exposure period, and the second exposure amount.
(FR) L'invention concerne un dispositif de mesure de distance et d'imagerie présentant un rapport signal-bruit élevé et une précision élevée de mesure de distance. Le dispositif de mesure de distance et d'imagerie comporte : une unité de génération de signal destinée à générer un signal d'émission lumineuse et un signal d'exposition lumineuse ; une unité de source lumineuse destinée à recevoir le signal d'émission lumineuse et à irradier la lumière selon le signal d'émission lumineuse reçu ; une unité d'imagerie destinée à recevoir le signal d'exposition lumineuse, à effectuer l'exposition selon le signal d'exposition lumineuse reçu, et à recueillir une quantité d'exposition lumineuse réfléchie ; et une unité de calcul destinée à calculer des informations de distance sur base de la quantité d'exposition et à sortir les informations de distance. L'unité d'imagerie recueille une première quantité d'exposition correspondant à l'exposition durant une première période d'émission et exposition durant laquelle le signal d'exposition lumineuse est reçu et l'exposition est effectuée en même temps que le signal d'émission lumineuse est reçu et une seconde quantité d'exposition correspondant à l'exposition durant une seconde période d'émission et exposition durant laquelle le signal d'exposition lumineuse est reçu et l'exposition est effectuée après qu'un délai s'est écoulé depuis la réception du signal d'émission lumineuse. L'unité de calcul calcule les informations de distance à partir de la première quantité d'exposition, qui est obtenue par la variation du nombre de répétitions de signal d'émission lumineuse dans la première période d'émission et exposition, et de la seconde quantité d'exposition.
(JA)  高S/Nで高い測距精度を有する測距撮像装置を提供する。測距撮像装置は、発光信号と露光信号とを発生する信号発生部と、発光信号を受信することにより光照射を行う光源部と、露光信号を受信することにより露光を行い、反射光の露光量を取得する撮像部と、当該露光量に基づいて距離情報を演算して出力する演算部とを備え、撮像部は、発光信号の受信タイミングと同時に露光信号を受信し露光を行う第一の発光露光期間において当該露光に対応した第一の露光量を取得し、発光信号の受信タイミングに対して遅延時間を経て露光信号を受信し露光を行う第二の発光露光期間において当該露光に対応した第二の露光量を取得し、演算部は、第一の発光露光期間における発光信号の繰り返し回数を可変することにより取得された第一の露光量と第二の露光量とから距離情報を演算する。
