A Novel Multi-Projection Correction Method Based on Binocular Vision

In order to improve the accuracy of multi-projection correction fusion, a method based on binocular vision is proposed. To date, most existing methods are single-camera mode, which may lose depth information display wall and not accurately obtain details geometric structure wall. The proposed uses camera build high-precision 3D model; thus, there no need know specific CAD size in advance. Meanwhile, this can be applied walls any shape. By calibrating camera, radial eccentric aberration reduced. projector projects encoded structured light stripes, structural projection screen reconstructed according phase relationship after collecting deformation stripes with camera. Thus, screen-projector sub-pixel-level mapping established, achieved. addition, by means one-to-one relation between three-dimensional space points, accurate point cloud matching among multiple sets could so that such quantity projectors. experimental results various special-shaped screens show that, comparing single-camera-based method, improves stitching more than 20%. This also has many advantages, as strong universality, high measurement accuracy, rapid speed, indicate its wide application potential different fields.
