摘　　要：针对海面情况复杂,舰船热尾流红外图像受干扰大,目标区域不易辨别的特点,提出了一种自适应滤波平滑技术并采用动态阈值分割算法对传统的Canny边缘检测算法加以改进。在实际应用中,提取出了清晰、连通的舰船热尾流的边缘,达到了令人满意的结果。为红外探测潜艇提供了科学的水面热轨迹情况的依据。Aiming at the complex conditions of sea surface and the infrared image of thermal wake of ship which is disturbed severely and hard to be discriminated, an adaptive technology of filter-smooth is proposed and segmentation algorithm based on dynamic threshold value is used to improve the traditional Canny edge-detection algorithm. The clear and continuous edges of thermal wake of ship are get in practical application and the result is satisfied. So, scientific bases are available for the infrared detection of submarines.
