基于视差自相关特征水深反演

提出了一种基于视差自相关特征模拟水深的新方法。这种方法利用不同摄站获取的同一物体的两幅图像,在水的折射影响下,造成的视觉上的偏差计算水深,可以得到相关区域三维显示中各点的水深数值。以数码相机所拍摄两张照片为例,实现相关区域水深三维显示。结果表明此算法具有一定的可行性,可以进行更深层次的研究,并应用于浅海、河流等地的资源探测开发。

Extracting water depth based on parallax of autocorrelation characteristics

We propose a new method simulating water depth based on parallax of autocorrelation characteristics by images of shallow sea.First,we take two pictures of a same object at different time,or the same time but at different angle. By point to point image matching,we get the deviation of each point.Then we calculate water depth by the deviation,and get data of each point in 3D image of relative area.In the paper,taking two seaside photographs as an example,and basing on the parallax algorithm,3D display about water depth of relative area is realized.The result indicates that the new algorithm is feasible.
