opencv中，由于使用Mat.at访问数据时，必须正确填写相应的数据类型，因此必须弄清楚opencv中的数据类型与我们常用 
数据类型一一对应关系。
Mat_<uchar>---------CV_8U（图像Mat类型）
Mat<char>-----------CV_8S
Nat_<short>---------CV_16S
Mat_<ushort>--------CV_16U
Mat_<int>-----------CV_32S
Mat_<float>----------CV_32F
Mat_<double>--------CV_64F(opencv 中一般Mat类型 float64 类型矩阵)
