A Study on Optimum Conditions for Compositing of Hologram and Real Image

A mixed reality in which reality and virtual coexist can increase a sense of presence and reality through complementation of virtual reality and augmented reality. Based on hologram technology, which is an ultra-realistic content, the number of mixed reality cases is increasing. Hologram technology can represent realistic expression of objects and visual expression beyond spatial limits by blurring the boundary between reality and virtual reality, rather than simple composition. It is impossible to perfectly synthesize and express images produced in different environments, but research on an optimal environment that can increase the sense of presence by reducing the sense of disparity as much as possible and maintaining a sense of unity is required. In this paper, the process of producing a pseudo hologram produced for broadcasting is divided into two types: a holographic video production workflow and a stage composition workflow with a live film, and present conditions to reduce the heterogeneity of the final composite video in each process. In each process, a new process was established, and details such as contents that are easy to overlook during production and necessary skills and characteristics are described. The process of matching images using traditional production methods is time consuming and expensive, and still has limitations. This is the time when automated processing to match the environment of the target image by presenting a reference image and analyzing basic information of the image is required.
