DISTANCE MEASUREMENT DEVICE, DISTANCE MEASUREMENT SYSTEM, DISTANCE MEASUREMENT METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2019/188374

Kind Code:

A1

Abstract:

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.
