Digital Image Curve Projection Correction

When projector of image project on a curvature of surface, Image can produce deformation on the surface.Many tutors working on search for the phenomenon find the influenced deformation of three important factors. Firstly project display of shape, different curvature of screens have different degree of geometric deformation; Secondly protector of geometric position geometric place of variation also affects effect of projection image; Thirdly distinct image proceeding algorithms of application can form quite difference on projector of image. Above all Searchers refer to some new methods for projection image. Based on the methods supply three steps for project of solution:I define a projection of curvature, then I compute out projection and projector space of geometric relation and deformation of matrix, Finally1may divide, extract corners and calculate out curve controlling corner information, following operation of matrix, in order to implement project image of nonlinear geometric transformation.
