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 propertiesIn 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 patterns in the area, wherein location of the patterns are pre-determined, wherein shape of the patterns are pre-determined, wherein color of the patterns are pre-determined, wherein the patterns are configured to contain encoded coordinate information, wherein the patterns are configured to be detected by optical or infrared means;   Capturing a first set of one or more images of the patterns by a first one of the plurality of cameras and a second set of one or more images of the patterns by a second one of the plurality of cameras;   Decoding the encoded coordinate information; and   Calibrating the first one of the plurality of cameras and the second one of the plurality of cameras by matching same pattern between the first set of one or more images of the object and the second set of one or more images and utilizing the encoded coordinate information that was decoded.   
     
     
         2 . The method for calibrating a plurality of cameras in an area of  claim 1  wherein the plurality of cameras are configured to move. 
     
     
         3 . The method for calibrating a plurality of cameras in an area of  claim 1  wherein a neural network is configured to match and identify the at least one feature points. 
     
     
         4 . The method for calibrating a plurality of cameras in an area of  claim 1 , further comprising:
 Recalibrating a subset of the plurality of cameras after a time period or when any of the re-projection errors exceeds a certain value.   
     
     
         5 . The method for calibrating a plurality of cameras in an area of  claim 1 , wherein translucent stickers covered with some infrared ink to mark the patterns.
