Problems solved by technology
However, in the existing multi-projection display system, the corresponding correction parameters are generally set during initialization, and automatic adjustment cannot be made for the movement of the projectors.
In addition, the existing multi-projection display systems generally do not consider the influence of the color texture of the projection background on the projection effect, and do not consider the color correction of the projection screen

Embodiment Construction
[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.
[0048] In the process of multi-projection automatic correction in the present invention, the autonomous geometric position correction subsystem establishes the mapping relationship between the projected picture and the real world, autonomously detects the projected picture and generates real-time geometric correction parameters. The background texture color correction subsystem is used to reduce the influence of the projected background texture on the observation effect and enhance the picture effect. The multi-projection display subsystem completes the network communication of the master control node, the embedding of structured light and the control of multiple display nodes to display images. Thus, the combination of autonomous geometric correct...

The invention relates to the fields of computer graphics, system software, computer networks and the like, in particular to a multi-projection autocorrection display system based on a camera. A multi-projection autocorrection display method comprises the steps of utilizing structured light to automatically perform geometrical position correction on a projection picture, performing color correction on the projection picture to reduce influence of background textures and utilizing a color enhancement technology to improve observation experience of the projection picture. An independent geometrical correction and color correction technology is integrated together under a multi-projection environment to solve the problems of projection picture distortion caused by projection background textures and projection picture splicing failure caused by movement of a projector. The invention further discloses an independent geometric correction subsystem, a background texture color correction subsystem and a multi-projection display subsystem for achieving the multi-projection autocorrection display system. The technical scheme is universally suitable for the multi-projection autocorrection display system aiming at projector movement and projection background screen textures and platform support can be provided for a high-resolution and large display screen projection display system which enables people to have a strong immersion feeling.
Description
technical field [0001] The present invention relates to the fields of computer graphics, system software, computer network, etc., and specifically relates to a camera-based multi-projection automatic correction display system, which includes three parts based on autonomous geometric position correction, background texture color correction and multi-projection display. Background technique [0002] The camera-based multi-projection automatic correction display technology is a technology that automatically realizes the splicing of images projected by multiple projectors and eliminates the influence of background texture on the viewing effect in application examples such as multiple projectors projecting on textured backgrounds. [0003] The multi-projection automatic correction display technology, that is, without artificially moving the projector and adjusting related parameters, uses the camera to independently complete the splicing between multiple projector screens in real ...
