摘要

由于水下目标回波检测方法无法获得目标的轮廓和形状等特征,给水下目标的检测带来困难。成像目标检测可以克服这一困难。但成像是一个复杂的过程,所获取的图像背景复杂,信噪比低。针对这些问题,开展了成像检测实验,获取了激光图像。提出了基于相关分析、K-L变换、形态学和分数的目标检测方法。实验证明,这些方法能够有效地检测出复杂背景下的弱小水下目标。

Underwater Laser Imaging Target Detection Technology
Since underwater target echo detection method can not gain characters such as target contour and shape, it is difficult to detect it. Imaging target detection can overcome the difficulty. But imaging is a complex process and the acquired images have complicated background and low signal to noise ratio. Aimed at these, imaging detection experiment is developed and laser images are acquired. Moreover, target detecting methods based on correlation analysis, K-L transform, morphology and fraction are proposed. Experiments proved that these methods could efficaciously detect small weak underwater target in complex background.
