摘　　要：水下光学成像探测技术是水下探测技术的重要组成部分,但水下环境错综复杂,直接或间接影响到水下图像采集过程和成像质量。文中基于LabVIEW软件设计水下图像采集存储和图像增强程序,利用LabVIEW视觉与运动采集组件和存储模块进行水下图像采集存储,利用NI视觉重构器和IMAQ视觉系统模块完成水下图像的增强,从而改善水下图像的对比度、RGB亮度及伽马校正,增强水下图像成像效果。经过多次测试验证,该程序具有性能稳定,水下图像存储及增强效果显著的特点,为水下图像采集存储、增强提供了新思路。Underwater optical imaging detection technology is an important part of underwater detection technology.However,the underwater environment is complicated,which directly or indirectly affects the underwater image acquisition process and image quality.The underwater image acquisition and storage and image enhancement program is designed based on LabVIEW(laboratory virtual instrument engineering workbench).LabVIEW vision and motion acquisition components and storage modules are used for underwater image acquisition and storage.The underwater image is enhanced by NI visual reconstructor and IMAQ visual system modules,so as to improve the contrast,RGB brightness and gamma correction of underwater image,and enhance the imaging effect of the underwater image.Many tests have shown that the proposed program has stable performance,remarkable effect of underwater image storage and enhancement.Therefore,it can provide a new idea for underwater image acquisition,storage and enhancement.
