Description

technical field

[0001] The invention relates to a three-dimensional display system and method, in particular to a free multi-viewpoint multi-projection three-dimensional display system and method. Background technique

[0002] Projection display is a kind of three-dimensional display method. There are many ways to display 3D images, mainly divided into those that require auxiliary tools and those that do not. Early stereoscopic display auxiliary tools mainly include helmet type and glasses type, and the glasses type has red and blue sheets, polarizers, etc. These three-dimensional display methods restrict people's viewing freedom due to the need to wear tools.

[0003] Research on 3D display methods that do not require auxiliary tools has been extensively developed. This will free people from glasses and helmets, and be able to freely watch stereoscopic images, enhancing the ease of use, interactivity and fun of use of the system. At present, the three-dimensional displa...
