Abstract: This paper proposes an exceptional points removing based optimal algorithm for estimating the fundamental matrix. Firstly, the exceptional points are eliminated, and the initial value of the fundamental matrix is obtained. Secondly, a criterion of minimizing the epipoalr distance is used to nonlinearly optimize the initial fundamental matrix. It can be seen from the experiment results that this algorithm eliminates the bad effect of exceptional points on the fundamental matrix, thus it is more precise and has an advantage over other conventional algorithms in terms of both average residual error and average epipolar distance.
