Algorithm for Automatic Generation of Sparse Image Array Based on View Morphing

The acquisition of sparse image array by the camera array is an important way to integrate imaging in the image acquisition phase. However, the camera array acquires a limited number of images and cannot meet the requirements of the application. This paper proposes a algorithm for automatic generation of sparse image array based on view morphing method by studying the relationship between the virtual viewpoint and the reference viewpoint. With this algorithm, we can estimate virtual viewpoint images at other locations in the sparse image array based on the reference viewpoint. Finally, the requirement to obtain a large number of sparse image array by capturing a reference image with a small number of camera arrays is achieved. This method can effectively increase the number of virtual viewpoint images in a sparse image array.
