Abstract
In this paper, a method of moving control of an automatic guided vehicle (AGV) through marker recognition is presented. The existing AGV location tracking system using infrared wireless sensor nodes and landmarks have faced at two critical problems. First of all, since there are many windows in the special circumstance such as a crematorium, they are going to let in too much sunlight in the main hall which is the moving path of AGVs. Refraction and/or reflection of sunlight disturb the correct recognition of landmarks. The second one is that a crematorium has a narrow indoor environment compared to typical industrial fields. Particularly when it changes its direction to enter a designated furnace the information provided by the landmarks cannot be utilized to estimate its location because the rotating space is too narrow to get them. To overcome such difficulties that cannot access data in a wireless sensor network, a relative distance from a marker to an AGV will be used as a fingerprinting for location estimation. Compared to the conventional method which adopts received signal strength (RSS) as fingerprinting, our proposed method results in highly reliable estimation.
