Distance measuring method and distance measuring device

摘要

A distance measuring method for performing distance measurement by projecting a distance measuring light to an object to be measured and by receiving a reflected light, comprising: a step of projecting for scanning the distance measuring light which has at least one luminous flux with a predetermined spreading angle; a step of emitting the light by pulsed light emission at least two times during a period when the luminous flux traverses the object to be measured; a step of measuring a distance by receiving the reflected light at least two times; and a step of averaging the results of the distance measurement.
