A distance measuring apparatus is disclosed, which measures the entire image of a target object by employing a light-section method within a short time, without assigning any specific feature to light beams having a beam form obtained by passing through slits. The apparatus comprises a device for simultaneously emitting such light beams; first and second image taking devices for taking an image obtained by light reflected by the target object, where the distance between the first image taking device and the beam emitting device is relatively short while the distance between the first image taking device and the beam emitting device is relatively long; a section for estimating the distance to the target object based on the image taken by the first image taking device; and a section for determining the distance based on the estimated result and on the image taken by the second image taking device.
