Method for estimating characteristic of the other signal using a correlation model in acoustic and video signal characteristic to air bubble wake of a ship

摘要

PURPOSE: A method for estimating the property of a corresponding signal is provided to estimate the property of a corresponding signal using a correlation model of an aquatic and video signal property. CONSTITUTION: A method for estimating the property of a corresponding signal is as follows. The acoustic signal about the bubble resistance of the aquatic box and video signal are obtained(S901). It is determined whether the signal obtaining as the source signal for the property estimation of the corresponding signal is the acoustic signal(S902). If the obtained signal is the video signal, the property of the bubble resistance using the video signal is analyzed and the characteristic values of the bubble resistance are extracted(S903). The video property value in which the acoustic signal and correlation have among the characteristic values of the extracted bubble resistance is extracted(S904). The property estimate of the acoustic signal about the bubble resistance is gotten with the application of the correlation model of acoustic and video signal(S906).
