Abstract

The present work consists of a methodology for the Capture and Representation of three-dimensional holograms in high definition. This proposal makes use of computational tools, such as Computer Vision and Artificial Intelligence, this methodology is divided into five phases or steps. In the first step the problems of the different techniques of 3D visualization are presented and how this project solves them, as is the use of 3D devices. While phase two is intended to explain the background of holography and holograms, it also explains how, making use of stereoscopic vision, devices, methods and techniques have been created that allow the visualization of 3D objects. That is why in the next phase gives the theoretical basis of the elements used in the construction of this project. Also, we explain how human eye obtains natural images, color spaces and principles to extract a chromatically pure color (ChromaKey green) as a scene background. The mathematical methodology is proposed in the fourth phase where all techniques are considered that are used for the construction and design of a capture module, which is used to perform the coding of the final hologram. In addition, the considerations for the construction of a module for the representation of the hologram and to visualize it in a holographic pyramid are exposed. Finally, the main experiments are presented and explained, with the holographic pyramid at two different angles of inclination, also we perform a test of illumination of the capture module, in addition we calibrate the turntable and process of coding and holographic representation.
