numbers accumulates into the matrix. Due to the presence of drift, the operation of the rotation may be wrong, so the matrix to be normalized, reset the matrix, which is a very time-consuming operation. The four-dollar number has only 4 values, and the matrix has 9, and it experiences little drift and less normalizati

And the online about findhomography introduction is relatively few, so will let people misunderstand findfundamentalmat will calculate the transformation matrix.Try to return the matrix with the Findhomography function, in the template image, the object is already marked with a green box outline, according to the object's four boundary points, and the transformation
