Abstract
A laser scanner recognizes reflectors arranged along a travelling path. A reflector having an angle or a distance falling within an allowable range relative to the last specified reflector is determined to be the same as the previous specified reflector. Based on the locational relationship between such reflectors and those having an angle or a distance outside the allowable range, the reflectors are specified by referencing a reflector map. The reflectors can be specified without assuming the present position of an automatic guided vehicle.
