Problems solved by technology

[0008] However, in the case of a wafer-level stereo camera, since two image sensors are arranged on one wafer, the distance between the centers of the two image sensors must be shortened, so that the distance information of objects from the camera cannot be accurately analyzed.

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.

Description

technical field [0001] The present invention relates to a distance measuring device, more particularly to a distance measuring device with dual stereo cameras, which can extract more accurate distance information by matching the depth maps of reference objects obtained by the two stereo cameras, wherein the two The stereo cameras each have two image sensors provided on one board. Background technique [0002] With the development of information communication technology, digital terminals that process characters, sounds, and images at high speeds have provided multimedia services that can support two-dimensional images and sounds, and regulations on three-dimensional information communication services that provide three-dimensional real multimedia services have been actively implemented Research. [0003] Generally, a three-dimensional image with a three-dimensional effect is obtained through the principle of stereo vision of two eyes. An important factor of the three-dimen...
