[opencv] Mat Depth

openCV Mat을 사용하면서 Mat을 초기화 하는 방법으로. 아래와 같은 파라미터들이 들어감. <초기화하는 방법>

	double m[3][3] = {{a, b, c}, {d, e, f}, {g, h, i}};
	Mat M = Mat(3, 3, CV_64F, m).inv();

	C++: int Mat::depth() const
	The method returns the identifier of the matrix element depth (the type of each individual channel). For example, for a 16-bit signed 3-channel array, the method returns CV_16S . A complete list of matrix types contains the following values:
	CV_8U - 8-bit unsigned integers ( 0..255 )
	CV_8S - 8-bit signed integers ( -128..127 )
	CV_16U - 16-bit unsigned integers ( 0..65535 )
	CV_16S - 16-bit signed integers ( -32768..32767 )
	CV_32S - 32-bit signed integers ( -2147483648..2147483647 )
	CV_32F - 32-bit floating-point numbers ( -FLT_MAX..FLT_MAX, INF, NAN )
	CV_64F - 64-bit floating-point numbers ( -DBL_MAX..DBL_MAX, INF, NAN )

파라미터 정보는 참고하여 항상 생성하도록 하자. 

Mat을 사용할 때는 아래와 같이 사용함.

	double dml1[3] = { 0, 340, 0 };
	double dmr2[3] = { 640, 330, 0 };
	Mat Lm = Mat(3,1,CV_64F, dml1);
	Mat Rm = Mat(3,1,CV_64F, dmr2);
	// method
	//const double *data = Lm.ptr<double>(0);
	Point2f tLRpt[2];
	tLRpt[0].x = Lm.at<double>(0,0);
	tLRpt[0] = Point2f( Lm.at<double>(0,0), Lm.at<double>(1,0) );
	tLRpt[1] = Point2f( Rm.at<double>(0,0), Rm.at<double>(1,0) );
	Mat m1 = H * Lm;
	Mat m2 = H * Rm;
