Estimating Intrinsic Camera Parameters Using the Sum of Cosine Distances
Yegor V. Goshin · Journal of Physics Conference Series · 2018
The paper presents a method for the estimation of camera motion parameters from a set of corresponding points by solving the problem of nonlinear optimisation. The parameters of camera motion are represented in the form of Euler–Rodrigues parameters. This approach makes it possible to avoid redundancy and further answer correction. Furthermore, the use of an angle as a measure of proximity enables us to reduce the problem to unconstrained optimisation, which provides a wider choice of its possible solutions.
