Method and system for reproducing visual content

-28 Abstract METHOD AND SYSTEM FOR REPRODUCING VISUAL CONTENT A method of generating an improved warp map for a projection on a non-planar surface. An initial warp map of the projection on the non-planar surface captured by a camera is received, the projection being formed on the non-planar surface using a projector and the initial warp map. A plurality of regions on the non-planar surface is generated, each of the plurality of regions having a size and location determined from a measure of flatness for the region based on the initial warp map. An unwarped image of a calibration pattern projected on the non-planar surface is determined by applying an inverse transform to each of the plurality of regions on the non-planar surface, each transform mapping pixels of the projection to pixels of the camera according to the initial warp map. A plurality of locations in the determined unwarped image of the calibration pattern is determined to generate the improved warp map. 21149267v1 -3/ 11 Start Project calibration pattern Capture calibration pattern Determine point correspondences 340 Auto-calibration 3 Determine content mapping Receive and pre process image content 380 Project content End Fig. 3
