利用计算机图像处理技术提取场景和目标信息是水下自动搜索、目标检测、跟踪、测绘和目标识别的关键。在浑浊的沃茨中，新一代声学摄像机，例如，DIDSON可以产生比光学传感器具有更高目标细节的图像。校准这些摄像机以建立数据和图像投影模型之间的一致性是准确估计定量信息（包括定位和图像配准）的先决条件。本文研究了DIDSON相机的内定标问题，以估计和校正透镜畸变，保证数据与模型的一致性
Computer image processing to extract scene and target information is critical in automated underwater search and inspection, target detection, tracking, mapping and object recognition. In turbid waters, the new generation of acoustic video cameras, e.g., a DIDSON, can produce images with higher target details than available from optical sensors. Calibration of these cameras to establish agreement between the data and image projection model is the prerequisite for the accurate estimation of quantitative information, including positioning and image registration. This paper addresses the internal calibration problem, in order to estimate and rectify the lens distortion in a DIDSON camera to ensure data to model consistency
