It is important to note that, since the transformation is linear, it must also be invertible, so the determinant of the matrix is non-zero.

Webb31 jan. 2024 · The first transformation matrix is called the Camera Extrinsic matrix. It tells us the position of our camera in the 3D space. The second transformation is the Camera Intrinsic matrix which converts the image plane to pixels. First, it scales the image plane from a unit (e.g., meters) to pixels. WebbFor the moment we do not know what is the matrix M and its coefficients correspond to. In reality, the coefficients are not directly found. Let’s rather say that there is a better way to decompose this matrix. Indeed a transformation matrix can be decomposed into 4 matrices, all playing a role in the transformation of coordinates in space.. We note the …
