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 from each of two or more known positions so that two or more objects to be measured are commonly included, a step of detecting reflected lights from the two or more objects to be measured for each pulsed laser beam by discriminating the reflected lights for each emitted pulse, a step of measuring distances to the two or more objects to be measured from each of the known points based on the results of detection of the discriminated reflected lights, and a step of measuring coordinate positions of the two or more objects to be measured based on the measured distances.
