System and method for real-time calculating location

A computerized method of calculating a location in real time based on an artificial mark, comprising the steps of:

• a) calculating by a processor a current initial location using an image coordinate recognized through turning on and off an artificial mark or assigning the current initial location as a predetermined location;
• b) identifying detected artificial marks through an artificial mark tracing process while traveling at a mark identifying module, where the artificial mark tracing process identifies an artificial mark detected at a current time as one of artificial marks detected at a previous time which is closest to the currently detected artificial mark;
• and
• c) updating a current location at a location calculating module based on the image coordinate of the detected and identified artificial mark and a pre-stored space coordinate in a main control module.

• b) identifying artificial marks detected while traveling at a mark identifying module by estimating an image coordinate of artificial mark at an image estimating module based on current location information of artificial mark calculated at a location calculating module and a space coordinate of artificial mark stored in the main control module, and comparing the estimated image coordinate and newly detected image coordinate;
• and
• c) updating a current location at a location calculating module based on the image coordinate of the detected and identified artificial mark and a pre-stored space coordinate in a main control module.

• a) calculating by a processor a current initial location using an image coordinate recognized through turning on and off an artificial mark or assigning the current initial location as a predetermined location;
• b) identifying artificial marks detected while traveling at a mark identifying module by performing an artificial mark tracing process on an image where the closest one of artificial marks detected a previous time stage is identified as an identical artificial mark or by estimating an image coordinate of artificial mark at an image estimating module based on current location information of artificial mark calculated at a location calculating module and a space coordinate of artificial mark stored in the main control module and comparing the estimated image coordinate and newly detected image coordinate when the artificial marks detected at the previous state are disappeared;

• c) updating a current location at a location calculating module based on the image coordinate of the detected and identified artificial mark and a pre-stored space coordinate in a main control module.
