The damage imaging method based on evidence theory data fusion is proposed in order to improve the contrast ratio and reliability of damage detection image. Time delay of sensing path is determined by continuous wavelet transform. Damage location image is carried out by using the ellipse location method.The weight value of the sensing path is determined by the frequency band energy rate of the signal. A weighted proportional conflict redistribution (PCR) evidence fusion algorithm is proposed, which is used to fuse the multi sensor path. The test results show that the algorithm has better image contrast ratio, and can reduce the influence of imaging result by the incorrect time delay of some sensing paths.
