Affine Calibration from Dynamic Scenes
R. A. Manning and C. R. Dyer, Computer Sciences Department Technical Report 1417

In Computer Sciences Department Technical Report 1397, the authors introduced a linear algorithm for determining the affine calibration between two camera views of a dynamic scene. In this paper, we expand upon the algorithm and investigate its performance experimentally. The algorithm computes affine calibration directly from the fundamental matrices associated with various moving objects in the scene, as well as from the fundamental matrix for the static background if the cameras are at different locations. A minimum of two fundamental matrices are required, but any number of additional fundamental matrices can be incorporated into the linear system to improve computational stability. The technique is demonstrated on both real and synthetic data.
