摘　　要：为了结合多种传感器的优点,得到更加符合实际的信息,在墙体渗漏检测中多层次运用了信息融合技术:对来自立体视觉系统的左、右两幅图像通过基于小波的多分辨率融合技术进行数据级融合;对视觉图像和墙体表面电阻信息进行特征级融合,可以为专业技术人员判断渗漏程度和渗漏原因提供更可靠的依据。In order to combine with advantages of multiple sensors, obtaining information which is more conformed to reality, multi-level information fusion technology is applied to wall water-leakage detection： Wavelet-Based Multi-resolution fusion method being used to fuse left and right images from stereoscopic system on data level： fuse vision image and information of resistance of wall surface on feature level. These methods can provide more reliable basis for leakage extent and cause evaluation made by the professional technical personnel.
