<p>An inline inspection system and method for calibrating an acoustic monitoring structure installed along a pipe. The system includes a pipe inspection vehicle, an acoustic source configured to generate sound waves inside the pipe, a mapping unit configured to record three dimensional motion data associated with the mapping unit, a microprocessor configured to attach time stamps to the three dimensional motion data; plural sensors disposed along the pipe and configured to record time of arrivals, intensities and frequencies of the sound waves generated by the acoustic source, and a processing unit configured to calibrate the acoustic monitoring structure based on the received time of arrivals, amplitudes and frequencies of the sound waves from the plural sensors, and calculated three dimensional spatial positions of the vehicle and associated time stamps.</p> |
