| 摘 要： | 为了综合利用不同反演参数下混凝土超声波层析成像的结果，采用基于小波变换的图像融合算法对两种射线追踪下的反演结果进行信息融合处理。应用实例表明，基于小波变换的图像融合可以有效综合不同图像的信息。该融合规则具有减少背景噪声、突出缺陷细节的效果，适用于混凝土超声波层析成像的图像融合。

| Abstract: | To comprehensively utilize the inversion results of different parameters, the image fusion algorithm based on wavelet transform was adopted to synthesize the images by straight ray tracing and bend ray tracing. The application example shows that the image fusion can effectively integrate the image information. And the fusion rule can significantly reduce background noise and highlight the defect details, which is suitable for the concrete ultrasonic tomography image. |
