Research on element image array generation method based on small number of multi-view images and homologous pixels mapping

Mapping the multi-view image group acquired by the sparse camera array into an element image array can effectively improve the display angle of stereoscopic source reconstruction images in the integral imaging display system, and can also avoid the crosstalk problem caused by the use of microlens array. However, the number of multi-view images collected by sparse camera array is small, and it is easy to lose details, which will increase the economic cost or time cost to collect sufficient number of multi-view images. Therefore, we propose a method to generate element image array based on mapping between a small number of multi-view images and homologous pixels. The pixel mapping relationship between multi-view image group and element image array is established. The experimental results show that the element image generated by the method proposed in this paper has a larger display view field and smooth transition of each view interval after stereoscopic source reconstruction.
