Abstract :
Data is sampled manually on a single underground metal pipe at a worksite with an existing electromagnetic induction underground metal pipe detector. Then the off-line computer processing is performed. Thus a fitted experiential formula of the secondary electromagnetic field of a single underground metal pipe is obtained. According to this experiential formula, identification of multiple pipes can be performed by fitting for experimental data
