Abstract
NDE probes provide unique data signals from a remote object such that can be used to accurately and precisely locate a position. With a computer processor, the data signals are converted into a positional fingerprint that is compact and easily analyzed as a file or information of probe position. The positional fingerprint is stored in association with the position or object to verify a same position at another time. Another probe detects other data signals for the object at another time. Under a similar transformation into a positional fingerprint, the position of the other probe can be matched to the first by comparing positional fingerprints. The comparison may use a probabilistic comparison and/or compare several different fingerprints from several different locations and times to ensure a best match. Position verification between probes may ensure a repair has been completed in the proper location, verify system integrity or investigate potential problems.
