A synthetic aperture de-occlusion algorithm based on the microlens array (MLA) is proposed. This kind of light field camera could obtain the original image data. This paper utilized the fusion synthetic aperture technique to identify occlusion foreground information. Moreover, OTSU was used to distinguish the pixel value range of the occlusion and the target object. The obscured object data can be identified. The image obtained by removing the occlusion information was refocused. The light field camera was utilized to extract the target image. Experiments show that the target image of this proposed algorithm is much better compared with other algorithms. The proposed algorithm in this paper also presents 3D scene images with high contrast and SNR. The evaluation value of unreferenced images is also increased by 20.03% on average.
