Carrier tracking system and method thereof

A carrier tracking system, applied in a predetermined space where a mobile carrier having an optical recognizable mark is in operation, and the carrier tracking system comprising:

• at least one optical capturing device, fixedly arranged in the predetermined space, the at least one optical capturing device configured to capture an image of the predetermined space;
• and
• a computing unit, communicatively coupled to the at least one optical capturing device, the computing unit configured to recognize optical recognized coordinate corresponding to the optical recognizable mark being captured in the image,
• wherein the optical recognizable mark is associated with information of materials carried by the mobile carrier, the computing unit is further configured to convert the optical recognized coordinate to real-space coordinate in the predetermined space, to associate the real-space coordinate with the information of materials, and to locate the mobile carrier.
