Smart Self Calibrating Camera System

Abstract

The present invention describes a system for calibrating a plurality of cameras in an area. The system functions by using certain patterns with visible or invisible properties In addition, the system implements automatic re-calibration in a specific way to reduce human intervention, cost and time.

1 . A method for calibrating a plurality of cameras in an area, comprising:
 Detecting feature points of a person, wherein the feature points are specific body area of the person, wherein the feature points are within range of the plurality of cameras, wherein dimensions of the specific body area of the person are measured and recorded;   Capturing a first set of one or more images of the feature points by a first one of the plurality of cameras and a second set of one or more images of the feature points by a second one of the plurality of cameras; and   Calibrating the first one of the plurality of cameras and the second one of the plurality of cameras by matching same feature points between the first set of one or more images of the object and the second set of one or more images.   
     
     
         2 . The method for calibrating a plurality of cameras in an area of  claim 1 , wherein the at least one feature points are not visible to human eyes and RGB cameras, wherein the at least one feature points are visible to infrared cameras. 
     
     
         3 . The method for calibrating a plurality of cameras in an area of  claim 1 , wherein the at least one feature points are lines, dots or polygons. 
     
     
         4 . The method for calibrating a plurality of cameras in an area of  claim 1 , wherein a user can manually be involved in the calibrating.
