Abstract
A position measuring system, comprising a distance measuring unit for projecting and scanning a pulsed beam for measurement to a measurement area and for measuring a distance based on a reflected light of the pulsed beam for measurement and for obtaining a position data group in the measurement area, a digital image pickup unit for acquiring an image data by taking an image of the measurement area, a storage unit for storing at least two sets of the position data groups and the image data acquired from at least two directions by interrelating and associating the position data groups with the image data, and an arithmetic unit for synthesizing the at least two position data groups through matching of the two images based on the two stored image data.
