Abstract
A three-dimensional map-generating apparatus and method using structured light. The apparatus for generating a three-dimensional map using structured light includes an odometer detecting the pose of a mobile robot, and a distance-measuring sensor including a light source module that emits light upward and a camera module that captures an image formed by light reflected from an obstacle, and measuring a distance to the obstacle using the captured image. The apparatus measures a distance to the obstacle using the distance-measuring sensor while changing the relative pose of the mobile robot, thereby generating a three-dimensional map.
