Abstract

The invention discloses a real-time volumetric three-dimensional data generation method based on a rotator three-dimensional display. By solving intersecting lines of a two-dimensional display plane and a triangular facet, two-dimensional display coordinates of every intersecting line on a two-dimensional light-emitting diode (LED) display screen in the rotator three-dimensional display are worked out finally, display colors under the two-dimensional display coordinates are obtained, conversion from triangle vertex data flow to volumetric three-dimensional data is finished, and real-time display of three-dimensional images is achieved. According to the real-time volumetric three-dimensional data generation method, the data volume of the volumetric three-dimensional data is small, consumed time for generating the volumetric three-dimensional data is short, and plenty of volumetric three-dimensional data can be generated in real time.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a method for generating real-time volumetric three-dimensional data based on a rotating three-dimensional display. Background technique [0002] The human visual system endows people with the ability to accurately perceive the image information of the real three-dimensional world, which makes people's visual pursuit always tend to the real three-dimensional reproduction. It is hoped that the display device can provide more real three-dimensional, natural and comfortable, close to the human eye 3D stereoscopic image information actually observed. Therefore, the development of three-dimensional stereoscopic display technology has attracted widespread attention. [0003] Existing 3D display technologies can be roughly classified into four categories: see-through 3D display, parallax 3D display, optical levitation display and true 3D display. True 3D d...
