| 摘 要： | 针对高频成像声呐多目标跟踪中声成像的不稳定问题，在基于检测前跟踪的声呐图像序列尺度不变特征变换（Scale Invariant Feature Transform，SIFT）的基础上，提出了一种结合对数变换的声呐图像序列SIFT特征跟踪方法。该方法利用对数变换进行图像预处理，进而利用声呐图像序列SIFT特征进行多目标跟踪。水池试验数据的处理结果表明：与中值滤波和动态亮度分配的方法相比，结合对数变换的声呐图像序列SIFT特征跟踪方法具有更好的多目标跟踪效果。

| Abstract: | The instability of acoustic imaging is still a challenge in multi-target tracking of high-frequency imaging sonar. Based on the SIFT (scale-invariant feature transform) feature tracking method using TBD (track-before-detect) technique, a SIFT feature tracking method with logarithm transformation for sonar image sequences is proposed. This method uses logarithmic transformation to preprocess images, and then uses the SIFT features of sonar image sequence to perform multi-target tracking. Logarithmic transformation can compress high gray-scale pixel values to improve the detection ability of weak targets and the stability of sonar imaging. The results of pool experiment show that the SIFT feature tracking method with logarithm transformation performs better in multi-target tracking of sonar image sequences, compared with the median filtering and dynamic brightness allocation method. |
