Localization system and method for mobile object using wireless communication

A localization method comprising steps of:

• requesting an optical indicator to emit an optical signal by a processing unit of a localization module comprising one or more optical indicators, the processing unit, and an RF transceiving means and transmitting a localization instruction for the optical indicator to one or more sensing modules through the RF transceiving means;
• detecting the optical signal of the optical indicator by an optical sensing means of the sensing module comprising one or more optical sensing means, an RF transceiving means, and a processing unit;
• calculating location information on the optical indicator by using the detected optical signal and a predetermined location of the sensing module by the processing unit of the sensing module, and transmitting the location information to the localization module through the RF transceiving means;
• and
• calculating the position of the mobile object from the received location information on the optical indicator by the processing unit of the localization module.

A localization method for a mobile object comprising steps of:

• requesting an optical indicator of a localization module comprising one or more optical indicators, an RF transceiving means, and a processing unit to emit an optical signal through the RF transceiving means by a processing unit of a central processing module comprising the processing unit and the RF transceiving means thereof, and transmitting a localization instruction for the optical indicator to one or more sensing modules;
• detecting the optical signal of the optical indicator by an optical sensing means of the sensing module comprising one or more optical sensing means, an RF transceiving means, and a processing unit;
• calculating location information on the optical indicator by using the detected optical signal and a predetermined location of the sensing module by the processing unit of the sensing module, and transmitting the location information to the central processing module through the RF transceiving means;
