Method and system for omnidirectional environmental projection with Single Projector and Single Spherical Mirror

摘要

The present invention relates to an omni-directional projection method and system based on a single projector and a spherical mirror that enables calibration using only a simple user input without accurate alignment of the projector and mirror in a general internal environment, The method includes determining the relationship between the geometric coordinates of the projection space and the pixel coordinates of the projector image, and the relationship between the geometric coordinates of the projection space and the pixel coordinates of the input image based on environmental geometric information specified by the user, and then the projector image and the input. An omnidirectional calibration step of defining a pixel coordinate relationship between images to generate calibration information; And producing a projection image that is projected omnidirectionally onto the projection space by transforming the input image based on the calibration information.
