ABSTRACT:
A distance measuring apparatus comprises projection means, light receiving means, computation means and scanning means. The projection means projects plural laser beams in different directions. The light receiving means receives the light reflected from each of objects in respective beam directions. The computation means computes the distances to the objects on the basis of the reflected light. And the scanning means sequentially changes the projecting directions of said plural laser beams.
