摘　　要：水下无线激光通信相比于水声、长波甚长波等传统水下无线通信手段具有明显的技术优势,而在水下特殊信道环境影响下,信号光斑易产生形变、闪烁,导致通信链路建立和维持难以进行。针对这一问题,提出了一种基于Qt和MATLAB混合编程的水下光斑目标跟踪软件设计方法,通过均值漂移(Mean shift)迭代算法实现水下目标光斑的识别和定位,采用MATLAB和Qt混合编程手段编写软件界面,搭建水箱实验平台并导入采集到的光斑序列图像。通过软件完成光斑目标识别和移动轨迹绘制,计算结果与实际光斑移动轨迹基本吻合,最大误差偏移量为7.28 pixel,验证了算法功能的有效性。Underwater laser communication has significant technological advantages over traditional underwater wireless communication methods such as acoustic,longwave,and verylongwave communication.However,the underwater environment makes the signal spot vulnerable to deformation and flicker,thus hindering the establishment and maintenance of a reliable optical link.To overcome this problem,we devise an underwater spot tracking software design approach based on Qt and MATLAB mixed programming.The approach adopts the Mean shift iterative algorithm for underwater spot target recognition and localization.A mixed programming method of MATLAB and Qt is used to create the software interface,build a water tank experimental platform,and import the spot photographs.Spot target recognition and movement trajectory drawing are realized using the software,thus verifying the effectiveness of the algorithm.The final result is essentially consistent with the actual spot trajectory,and the maximum error offset is 7.28 pixel.
