针对多投影图像几何校正过程受投影场景限制的问题，通过改进经典的基于Bezier曲面几何校正算法，提出一套适合不同拍摄条件下的几何校正方案。该方案根据不同的投影场景特性，采取合理的方法步骤，建立预扭曲图像与原始图像之间的转换关系，对原始图像进行几何预扭曲变换，使投影图像符合要求。实验结果表明，经几何校正后，各投影图像无几何畸变，衔接处几何内容完全匹配。该方案操作简单，运算复杂度低，系统成本小，适应不同的投影场景。

In order to solve the geometric correction limition of multi-projection images caused by projection scene. Through improving the classical calibration algorithm based on the Bezier surface, a geometric correction scheme for different shooting conditions was put forward. The scheme took reasonable steps according to the different characteristics between projection scenes, and established the conversion relation between the pre-distorted image and the original image. The projected images met the requirements because of the pre-distorted geometry transformation of original images. The experimental results indicate that the projection images are without geometric distortion and the geometric contents are completely matched at connection section after geometric correction. The proposed solution is simple to operate with low computational complexity and small system cost, also is suitable for different projection scenes.
