侧扫声纳图像增强技术

Processing Techniques of Enhancement for Side Scan Sonar Images

随着海洋探测技术的飞速发展,侧扫声纳的图像质量和定位精度迅速提高,其应用日益广泛和深入。在声纳图像判读分析时,常常需要进行辐射改正和均衡增强。根据海底地貌声纳图像的特点,归纳了几种有效、适用的图像增强方法,并建立了声纳图像分析软件。

With the rapid development of hydrographic survey technology, the image quality and orientation precision of side-scan sonar are improved rapidly, and their application are abroad, When sonar images are interpreted and analyzed, it is often necessary that the radiometric distortion and the histogram equalization are processed, According to the characteristic of the sonar image of seafloor relief,some effective and applicable image enhancement methods are concluded, and the sonar images analysis software is established,
