Abstract
(EN)
Provided are a distance measurement device, a distance measurement system, a distance measurement method, and a program which make it possible to improve the resolution of a measurement distance. A distance measurement device (10) is connected to: a wave transmitting module (2) that transmits a measurement wave (W1); and a wave receiving module (3) that includes a first wave receiving unit and a second wave receiving unit for receiving the measurement wave (W1) which has been reflected by a target object (4). The distance measurement device (10) is configured such that a first wave receiving period in which the first wave receiving unit receives the measurement wave (W1) and a second wave receiving period in which the second wave receiving unit receives the measurement wave (W1) overlap each other temporally, and such that a start timing for the first wave receiving period and a start timing for the second wave receiving period are offset from each other by a temporal difference that is shorter than either the first wave receiving period or the second wave receiving period.

L'invention concerne un dispositif de mesure de distance, un système de mesure de distance, un procédé de mesure de distance et un programme qui permettent d'améliorer la résolution d'une distance de mesure. Le dispositif de mesure de distance (10) est connecté à : un module de transmission d'onde (2) qui transmet une onde de mesure (W1); et un module de réception d'onde (3) qui comprend une première unité de réception d'onde et une deuxième unité de réception d'onde permettant de recevoir l'onde de mesure (W1) qui a été réfléchie par un objet cible (4). Le dispositif de mesure de distance (10) est conçu de telle sorte qu'une première période de réception d'onde dans laquelle la première unité de réception d'onde reçoit l'onde de mesure (W1) et une deuxième période de réception d'onde dans laquelle la deuxième unité de réception d'onde reçoit l'onde de mesure (W1) se chevauchent temporellement l'une et l'autre, et de telle sorte qu'un moment de début pour la première période de réception d'onde et un moment de début pour la deuxième période de réception d'onde soient décalés l'un par rapport à l'autre par une différence temporelle qui est inférieure soit à la première période de réception d'onde, soit à la deuxième période de réception d'onde.
