Research progress of computational integral imaging

Abstract

Integral imaging technology would be one of the most promising technology for the battlefield visualization in future war. The reconstruction of integral imaging can be classified into optical reconstruction and computational reconstruction. Computational reconstruction is accomplished by computer simulation of the optical integral imaging reconstruction process, which can overcome many problems caused by device limitation in optical integral imaging system and improve the image quality through digital processing technology. The reconstructed image is digital format, which can provide data support for 3D depth extraction, 3D target recognition, 3D image processing and so on. Based on the principle of integral imaging, this paper focuses on the principle and development history of computational reconstruction, and compares the performance of two computational reconstruction methods.
