Compensated_Calibration_FPP

The code and data show 3D reconstruction results of a checkerboard, using different calibration and reconstruction methods. (1) with general stereo calibration and linear reconstruction, (2) with general stereo calibration and approximately undistorted reconstruction, (3) with stereo calibration and undistorted reconstruction using nonlinear epipolar constraints, and (4) with the residual distortion-calibrated reconstruction.

Instructions:
Simply download all the files and data at any folder location of a computer. Change the working dictionary to the folder in MATLAB (2016 or after) and run the Demo.m to get the four reported reults.
Please note that MATLAB Parallel Computing Toolbox is required for accellerated computation.

The code has been tested with MATLAB 2016, under a Windows OS.

To challenge the results using your own algorithm, please refer to the calibration images with the DOI: 10.21227/6f7p-jd52

本代码与数据集展示了采用不同标定与三维重建方法得到的棋盘格三维重建结果：(1) 通用立体标定结合线性重建；(2) 通用立体标定结合近似无畸变重建；(3) 基于非线性极线约束的立体标定与无畸变重建；(4) 残差畸变标定后的重建方法。

使用说明：
可将所有文件与数据集下载至计算机任意文件夹路径。在MATLAB（2016及以上版本）中将工作目录切换至该文件夹，运行Demo.m即可得到文中所述的四种重建结果。

请注意，若需加速计算，需安装MATLAB并行计算工具箱。
本代码已在Windows操作系统下的MATLAB 2016环境中完成测试。

若需使用自研算法验证或挑战上述结果，请参考DOI编号为10.21227/6f7p-jd52的标定图像数据集。
