Abstract
A distance measuring apparatus having dual stereo cameras includes a first stereo camera including left and right CMOS image sensors provided on one board and detecting parallax of a reference object to extract distance information, the left CMOS image sensor being spaced apart from the right CMOS image sensor at a predetermined interval, a second stereo camera separated from the first stereo camera at a predetermined distance, including left and right CMOS image sensors provided on one board, and detecting parallax of the reference object to extract distance information, the left CMOS image sensor being spaced apart from the right CMOS image sensor at a predetermined interval, and a depth map matching unit that extracts distance information on the reference object by comparing the distance information on the reference object acquired through the first stereo camera with the distance information on the reference object acquired through the second stereo camera.
