摘要
采用侧扫声纳结合GPS、陀螺仪等,构建深水沉排水下自动成像采集系统。给出了系统数据采集、去噪、数据成像等关键技术的设计和实现方案。研究了深水沉排水下声纳成像色彩映射及图像增强关键技术,提出了一种利用伪彩技术增强深水排体声纳图像清晰度方法,构建了综合图像清晰度评价指标的图像清晰目标优化函数,实现了水下声纳成像色彩增强。
By using side-scan sonar combined with GPS and gyroscope,the key technologies of automatic imaging and image recognition were analyzed in this paper.An underwater monitoring software system which used in the process of deep-water sinking construction was developed.Meanwhile,the color mapping of imaging of underwater sonar and the key technologies of image enhancement were researched.In this paper,a method was presented that using pseudo-color technology to enhance the image clarity of sonar.Finally,an objective optimization function of image sharpness with a comprehensive evaluation was established.
