Abstract
Provided is a system and method for providing location information of robot in real time using an artificial mark. The system includes: an image processing module for obtaining an image signal by photographing artificial marks installed at a predetermined space with a space coordinate and detecting an image coordinate of artificial mark from the obtaining the image signal; a location calculating module for calculating a current location by comparing the image coordinate of detected artificial mark and a pre-stored space coordinate of artificial mark; and an artificial mark identifying module for updating current location information by selectively using one of an artificial mark tracing process and an image coordinate estimating process.
