Methods and systems for generating a fingerprint for verification of a reference object

摘要

METHODS AND SYSTEMS FOR GENERATING A FINGERPRINT FOR VERIFICATION OF A REFERENCE OBJECT Disclosed herein are a method (300) and systems (100, 200) for generating a 5 fingerprint (146) for verification of a reference object (104), such as a layer or ply during a composite laminate layup procedure. An exemplary method includes the steps of generating (302) at least one reference image (144) of the reference object; removing (304) lighting effects from the at least one reference image to generate at least one processed image; generating (306) a reference fingerprint (146) for the reference object 10 based on the at least one processed image; generating (308) at least one candidate image of a candidate object; generating (310) a candidate fingerprint for the candidate object based on the at least one candidate image; and comparing (312) the candidate fingerprint and the reference fingerprint to determine a correlation. An alert is generated (314) based on the comparison. The alert is indicative that the correlation between the candidate 15 fingerprint and the reference fingerprint exists. 11293105v1 30 300-> 3/3 GENERATING AT LEAST ONE REFERENCE IMAGE OF A REFERENCE OBJECT 304 GENERATING AT LEAST ONE PROCESSED IMAGE FROM AT LEAST ONE REFERENCE IMAGE (OPTIONALLY REMOVING LIGHTING EFFECTS) 306 GENERATING A REFERENCE FINGERPRINT FOR THE REFERENCE OBJECT BASED ON AT LEAST ONE PROCESSED IMAGE GENERATING AT LEAST ONE CANDIDATE IMAGE OF A CANDIDATE OBJECT 310 GENERATING A CANDIDATE FINGERPRINT FOR THE CANDIDATE OBJECT BASED ON AT LEAST ONE CANDIDATE IMAGE 312-, 7 COMPARING THE CANDIDATE FINGERPRINT AND THE REFERENCE FINGERPRINT TO DETERMINE A CORRELATION BETWEEN THE CANDIDATE FINGERPRINT AND THE REFERENCE FINGERPRINT GENERATING AN ALERT BASED ON THE COMPARISON OF THE CANDIDATE FINGERPRINT AND THE REFERENCE FINGERPRINT, WHEREIN THE ALERT IN INDICATIVE THAT THE CORRELATION BETWEEN THE CANDIDATE FINGERPRINT AND THE REFERENCE FINGERPRINT EXISTS
