|
Projects a square image onto most curved surfaces without (much) distortion. |

Non-Uniform Projection Surface |
| 1.) A test pattern like the one below is projected onto the surface. A still camera is used to capture the projected image, which is then analyzed by the software to measure the distortion introduced by the surface. | |

| 2.) The image to be projected is shown below as a source image and as it appears when projected without our software. | |

| 3.) The software uses the analysis from (1) to distort the source image in such a way that it will appear undistorted when projected on to the curved surface. | |
