Absolute position detection system

An absolute position detecting system comprising:

• multiple pattern parts arranged on a traveling path of a vehicle at a predetermined distance and including at least one or more of first and second patterns;
• a pattern scanning part installed in the vehicle and scanning each of the multiple pattern parts using laser beams and measuring a light reflection time for each of the first and second patterns;
• a data processing part comparing the measured light reflection time with a predetermined reference light reflection time, processing the comparison result into binary data and recognizing the multiple pattern parts;
• and
• a position detecting part detecting absolute positions of the multiple pattern parts using the processed binary data and information on a distance between the multiple pattern parts.

An absolute position detecting system comprising:

• multiple pattern parts arranged on a traveling path of a vehicle at a predetermined distance and including at least one or more of first and second patterns;
• a pattern photographing part installed in the vehicle, photographing each of the multiple pattern parts and measuring a brightness value for each of the first and second patterns;
• a data processing part comparing the measured brightness value with a predetermined reference brightness value, processing the comparison result into binary data and recognizing the multiple pattern parts;
• and
• a position detecting part detecting absolute positions of the multiple pattern parts using the processed binary data and information on a distance between the multiple pattern parts.
