The homography matrice can be computed directly from translation and rotation:

It has the following form for a 2D case:

| cosA   sinA  tX |
|-sinA   cosA  tY |
|  0      0    1  |

where A is the angle of rotation, tX and tY is the translation of the image. If you want 3D projection, you need to add one more dimension to the matrix, but it still can be calculated directly from the translations and rotations.
