ABSTRACT:
A light wave distance measuring method, using a light wave distance measuring system with a focusing function, comprising a step of comparing a reference distance to an object to be measured obtained based on a position of a focusing lens with a measuring distance obtained by light wave distance measurement, and a step of defining the measuring distance approximately equal to the reference distance as a result of measurement.
