Abstract:

We presented a 3D restoration of 2D projection acquisition based correction algorithm for three types of distortion, keystone, oblique and wave height distortion, which were caused by bad photography conditions in marine environment monitoring. A distorted image was restored by coordinate offset and tilt offset correction. Experimental results show that the algorithm can restore a distorted image of any coordinate with higher accuracy and applicability.

Key words: wave measurement, distortion correction, coordinate offset, tilt offset
