WebThe essential matrix E has special structure, as we now show. For any vector v orthogonal to t, the deﬁnition of cross product yields k[t] vk= ktkkvk: Because of this, the matrix [t] maps all unit vectors in its row space into vectors of magnitude ktk. In other words, the two nonzero singular values of [t] are equal to each other (and to ktk). WebThe essential matrix and the fundamental matrix. To calculate depth information from a pair of images we need to compute the epipolar geometry. In the calibrated environment we capture this geometric constraint in an algebraic representation known as the essential matrix. In the uncalibrated environment, it is captured in the fundamental matrix.
