OpenCVSharp_保存浮点型Mat数据

Posted 2021-06-19 x1angzeeD.

OpenCVSharp提供了Mat的序列化和反序列化方法-----FileStorage类

直接上干货：

保存浮点型Mat:

Mat HomMat2dData = new Mat(2, 3, MatType.CV_64F);//模拟浮点型Mat数据
HomMat2dData.Set<double>(0, 0, 0.1124);
HomMat2dData.Set<double>(0, 1, -0.2211);
HomMat2dData.Set<double>(0, 2, 2.3669);
HomMat2dData.Set<double>(1, 0, 5.4557);
HomMat2dData.Set<double>(1, 1, 7.0101);
HomMat2dData.Set<double>(1, 2, -6.3314);
FileStorage fs = null;
try
{
    fs = new FileStorage( "HomMat2D.xml", FileStorage.Modes.Write);//文件于Debug目录下
    fs.Write("HomMat2dData", HomMat2dData);//注意这里name与value名称保持一致
    fs.Release();
}
catch
{
    fs.Release();
    MessageBox.Show("Error!");
}

读取浮点型Mat:

FileStorage fs = null;
try
{
    fs = new FileStorage("HomMat2D.xml", FileStorage.Modes.Read);
    Mat data = (Mat)fs["HomMat2dData"];//读出的数据。注：保存与读取用的名字应保持一致
    fs.Release();
}
catch
{
    MessageBox.Show("Error!");
    fs.Release();
}
