ABSTRACT:
An electro-optical distance measuring method for measuring a distance to an object to be measured by receiving a reflected light from the object to be measured, comprising: a step of projecting a pulsed laser beam with a predetermined spreading angle so as to include two or more objects to be measured; a step of discriminating and detecting the reflected lights from the two or more objects to be measured for each emitted pulse; and a step of measuring distances to the two or more objects to be measured based on the results of detection of the discriminated reflected lights.
