c++ - 使用 cv::fileStorage 保存双变量

Question

我有一个运行相机校准的校准程序。我想将校准结果保存在一个YML文件中，该文件可以正常工作，除非我尝试保存重 投影错误，这是我所做的双倍值：

cv::FileStorage fs= cv::FileStorage("calibration_result.yml",cv::FileStorage::WRITE); /*creating the storage file for the calibration results */

.......................................................


this->fs << "the camera matrix is "<<this->cameraMatrix;
.....................................................................
        this->fs<< "the number of used frames is "<<this->actualnumberOfFrames;
        ///this->fs<< " the reprojection error " << this->reprojectionError;   when I activate this line the storage stops at the **actualnumberOfFrames**
        this->fs<<"the used resolution is " << this->theFrameSIZE;
        this->fs << "used flags in the calirbation function" << this->flagsName;
        this->fs<<"the distortion Coefficients are "<< this->distortionCoeff;
        this->fs<<"the rotation vector is "<< this->rvec;
        this->fs <<"the tangiantiale vector" << this->tvecs;
......................................................

我仔细检查了变量值，它很好，我真的在结果文件中找到了值！

任何想法我可以如何解决这个问题？提前感谢您的帮助！

您是否尝试过删除姓名开头的空格？

从：

this->fs<< " the reprojection error " << this->reprojectionError;   

至：

this->fs<< "the reprojection error " << this->reprojectionError;
