—This paper discusses the reconstruction of sea-surface photo imaging based on Light Detection and Ranging (LIDAR) scanning observation, the new framework consists of three phases. Firstly, we set the angles and range of the image to perform the scanning to get the pixel coordinates of sea-surface image in x and y direction respectively. Secondly, we get the continuous signal and sampled by using aperture filter and combine the patches into the piecewise form to achieved the smoothly reconstruction. Finally, we applied the adaptive filter to increases the resolution of the image and to filter out the noise present in the image. The proposed method demonstrates the better reconstruction of sea-surface image. In addition we performed error simulation and the noise evaluation of the aperture filter, and it is noted that the error is significantly reduced compared with other method.
