Panoramic projection system and method

Abstract

The present invention discloses a panoramic projection system and method. The system includes a projection room, an image acquisition device, a control device and a projector group; the projection room is used for providing a projection space; the image acquisition device is used for acquiring a panoramic image/video and panoramically mapping the rectangular layout of the panoramic/video to a panoramic sphere and making the panoramic sphere externally tangent to the geometric model of the projection room; the control device is used for establishing a virtual camera which is located at the geometric center of the geometric model of the projection room and controlling the virtual camera to take pictures of the surfaces of the geometric model of the projection room; and the projector group islocated inside or outside the projection room and is used for projecting the pictures of the surfaces of the geometric model of the projection room shot by the virtual camera onto corresponding surfaces in the projection room. With the panoramic projection system and method provided by the invention adopted, the panoramic image can be panoramically projected onto a projected object, and therefore, when a user views a projection in the projected object, the immersive experience of the user can be increased.

Description

technical field [0001] The present invention relates to the field of panoramas, in particular to a panorama projection system and method. Background technique [0002] Panoramic projection is the use of multiple projection devices (such as ordinary projectors, laser projectors, etc.) to project panoramic images or three-dimensional scenes (such as first-person game scenes) onto the projected object (such as the six walls of the room), Generally speaking, it is a closed space. [0003] Generally speaking, panoramic projection is a way of viewing panoramic images or 3D scenes. At present, there are two main ways of viewing panoramic views: one is to use ordinary screens to view panoramas, such as PCs and mobile phones to view panoramas. This method of viewing panoramas has disadvantages Due to the screen size limitations of mobile phones and PCs, there is no sense of immersion in panoramic viewing; another viewing method is to use VR glasses. The disadvantage of this method o...

[0003] Generally speaking, panoramic projection is a way of viewing panoramic images or 3D scenes. At present, there are two main ways of viewing panoramic views: one is to use ordinary screens to view panoramas, such as PCs and mobile phones to view panoramas. This method of viewing panoramas has disadvantages Due to the screen size limitations of mobile phones and PCs, there is no sense of immersion in panoramic viewing; another viewing method is to use VR glasses. The disadvantage of this method of viewing panoramic views is that the preparations before viewing are cumbersome (need to adjust the interpupillary distance, myopia, etc.), Multiple viewers cannot watch at the same time, and multiple viewers cannot discuss the same panoramic image
