SYSTEM AND METHOD FOR REAL-TIME CALCULATING LOCATION

摘要

A system and a method for artificial target-based real time location calculation are provided to calculate the location of a robot regardless of the traveling state of the robot. A system comprises an image processing module(3), a location calculation module(4), and a target discriminating module(6). The image processing module detects image coordinates of the artificial target serving as a target of a light source for emitting light of a specific wavelength having a specific identification from the image signal acquired by photographing the artificial target arranged in a specific space. The location calculation module calculates the present location by matching the detected image coordinates of the artificial target and pre-stored space coordinates of the artificial target. The target discriminating module performs artificial target tracking and image coordinate estimation, and compares the estimated image coordinates and the detected image coordinates, and updates the present location position by selectively using the image coordinate estimation for discriminating artificial targets.
