Abstract
A distance measurement device of an embodiment includes a first device including a first reference signal source and a first transmitter-receiver, a second device including a second reference signal source and a second transmitter-receiver, and a calculation unit configured to calculate a distance between the first device and the second device. One of a first distance measurement signal and a second distance measurement signal is transmitted once or more, and another is transmitted twice or more. The calculation unit calculates the distance based on a total of three or more pieces of first phase information and second phase information acquired through transmission of the distance measurement signals three times or more in total, a first sampling period based on a first reference signal, and a second sampling period based on a second reference signal.
