The matrix contains the 3-D world points in homogenous coordinates that are projected into the image. Deriving Projection Matrices Of the basic matrix transforms in any 3D graphics programmer's toolkit, projection matrices are among the more complicated. Translation and scaling can be understood at a 压缩感知中的数学知识： 投影 矩阵 （ projection matrix ） def projection_matrix_1d (b): """Compute the projection matrix onto the space spanned by `b` Args: b: ndarray of dimension (D,), the basis for the subspace Returns: P: the projection matrix """ D, = b. shape # Notice that this b is a 1D ndarray, so b.T is an no-op. Use np.outer instead # to implement the outer product. numerator = np.

Ground plane Camera 1 1 O We add the perspective projection matrix as the first element in the multiplication that generates the complete transformation. Remember that since the position vector is multiplied on the right hand side that matrix is actually the last. First we scale, then rotate, translate and finally project.
