Embodiment Construction
[0032] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.
[0033] In order to solve the limitation that the digital projector is exposed outside the spherical screen in the rear projection form of the existing spherical display system, and the space constraints for the arrangement of functional auxiliary facilities are limited, and to solve the problem that the center angle of the effective area of the spherical screen in the front projection form of the spherical display system is relatively small Due to small limitations, a spherical display system based on a fisheye lens with a large field of view is designed. It can be configured as a single-channel orthographic projection; this system uses a fisheye lens with a large field of view. On a continuous image field, the image field has the same shape as the spherical curtain, and the image field can effectively cover the range of the center angle β of the s...
