The AR (Augmented Reality) Sudoku Solver is a tech demo that uses the phone's camera to find sudoku grids, solve them and project the results back into the picture. The program expects the grid to be freestanding, flat and not manually filled. Best results are achieved in good lightning conditions. The solver does not try to solve grids with less than 20 symbols (not restricted to numbers). All symbols must appear at least once. Use the volume keys to toggle debug visualizations. This is not a game, just a tech demo without any practical application that I know of. 在AR（增强现实）数独解算器是使用手机的摄像头找到数独电网，解决问题和项目回的图片结果的技术演示。 该计划预计电网是独立的，平坦的，没有手工填写。 最好的结果是在良好的照明条件下实现的。解算器并不试图解决电网少于20码元（不局限于数字）。所有的符号必须出现至少一次。 使用音量键来切换调试可视化。 这不是一个游戏，只是没有说我所知道的任何实际应用的一个技术演示。
Completely rewrote the image capture part, processing remains unchanged. So far tested with Nexus S and Nexus One. I hope that this will make it work on Droid phones and the new Samsung Galaxy S2, but I have no test devices available, so it is all guess-work. Please let me know through comments if it improves/deteriorates compatibity.
