抽象的。本文简要介绍了适用于水下环境观测的水声观测技术的选择和水下视频技术的某些方面。审查分为两节，每个主题一节，每节最后讨论各自领域目前面临的挑战。审查的声学部分涉及水深和几何测量、成像声纳、地下穿透剖面仪、定位方法、水声通信和传感器网络以及水速测量。本部分最后讨论了海洋声层析成像和被动声学监测的温度测量。水下视频部分首先处理获取问题，包括水下能见度、平台类型、视频格式、图像传感器和专用摄像机。然后是关于处理技术的注释，包括马赛克、立体视频、结构光、记录和传输、图像增强技术，并以对水下全息相机的简短讨论结束。
Abstract. This paper is a review which briefly describes a selection of acoustic observation techniques and certain aspects of underwater video technology suitable for observations in an underwater environment. The review is divided into two sections, one for each subject, where each section concludes with a discussion of the current challenges within the respective fields. The acoustic section of the review covers bathymetric and geometrical measurements, imaging sonars, subsurface penetrating profilers, positioning methods, acoustic underwater communication and sensor networks, and water speed measurements. The section ends by considering temperature measurements by ocean acoustic tomography and passive acoustic monitoring. The underwater video section initially deals with questions of acquisition including underwater visibility, the type of platform, and video formats, image sensors and specialized cameras. This is followed by notes on processing techniques including mosaicking, stereo video, structured light, recording and transmission, image enhancement techniques and ends with a short discussion of underwater holographic cameras.
