Abstract:

To solve the location shooting problem of the elemental image array in integral imaging which is as the result of the pickup device limitations,a novel method to generate elemental image array from the sparse viewpoint images by parallel mapping was proposed.First,a camera array was used to capture the sparse viewpoint images of the objects.Then,the horizontal and vertical disparity maps of every image were calculated,respectively,and the spatial location of the actual object point corresponding to every pixel in the image was reconstructed.Finally,the elemental image array was generated by using the parallel mapping algorithm.For the holes which still exist in the elemental image,the interpolation algorithm was uesd to fill them.The captured sparse viewpoint images and the synthesized elemental image array were presented in the experimental results.The experiment results show that the synthesized image has continuous visual angles and can truly represent the space structure of the subjects.And the proposed method is superior to the traditional elemental image array pickup method in the implementation.

Key words: information processing, integral imaging, sparse viewpoint pickup, parallel mapping
