摘要/Abstract

摘要： 根据海面图像的单应进行距离估算对于海洋工程具有重要意义。结合导管架入水参数观测问题，提出一种海面图像单应的估算方法。该方法以导管架上表面为参考平面，依据其单应矩阵及它与海平面之间的夹角计算出海面图像的单应。重点介绍了根据特征直线计算平面单应矩阵时的数据归一化方法。通过实验分析了这种归一化方法对平面远处距离估算的影响，并根据现场图片中的距离估算误差说明了在实际应用中的效果。该方法可以应用到多种海洋观测当中。

Abstract: Displacement estimation based on ocean surface homography is very important in ocean engineering.An algorithm is proposed for estimating the homography of ocean surface in jacket launching.The approach takes the jacket upper surface as a reference plane，computes the homography of ocean surface by the homography of reference plane and jacket launching angle.A normalization method on line based homography estimation is mainly introduced，and the effect of the normalization to the distance measurement in long distances is analyzed by experiments.The effect is also demonstrated with a scene photo of jacket launch.The approach can be widely applied in ocean observation.
