DISTANCE MEASURING SYSTEM

摘要

[Object] To achieve high-precision distance measuring with a reduced error in a distance measuring system which calculates a distance from an arrival time of each pulse signal constituting a pulse sequence. [Solving Means] For an oscillator which generates pulse signals by counting the number of pulse signals constituting a received pulse sequence, a relative time difference between a transmitting device 2 and a return device 3 is acquired, a distance from the transmitting device 2 to the return device 3 is calculated, and the calculated distance is corrected based on the calculated relative time difference.
