BEACON TO MEASURE DISTANCE, POSITIONING SYSTEM USING THE SAME, AND METHOD OF MEASURING DISTANCE |
摘要 |
A beacon to measure a distance based on a time difference between a transmitted light and a reflected light and to put the measured distance information into the lights, and a positioning system to detect a position of a moving body using the beacon, and a method thereof. Since a relative position of the moving body with respect to the beacon is precisely detected and infrared laser having directionality is used as a light source, the moving body can travel in a wide working area.
