SYSTEM, METHOD, AND MEDIUM FOR DETECTING MOVING OBJECT USING STRUCTURED LIGHT, AND MOBILE ROBOT INCLUDING SYSTEM THEREOF
First Claim
1. A system for detecting a moving object, the system comprising:
- an image obtaining unit to obtain a first image at a predetermined position and a second image at a position after a movement of the system by using a light source;
an image predicting unit to predict the second image at the position after the movement of the system by using the first image and information pertaining to the movement of the system; and
a comparing/analyzing unit to compare and analyze the second image obtained by the image obtaining unit and the second image predicted by the image predicting unit to detect the moving object.

Abstract
A system, a method, and medium for detecting a moving object using a structured light, and a mobile robot including the system are provided. The system includes an image obtaining unit to obtain a first image at a predetermined position and a second image at a position after a movement of the system by using a light source; an image predicting unit to predict the second image at the position after the movement of the system by using the first image and information with respect to the movement of the system; and a comparing/analyzing unit to compare and analyze the second image obtained by the image obtaining unit and the second image predicted by the image predicting unit.
