Using Homogeneous Coordinates to Solve The Problems of Determining The Orientation Parameters of Non-Metric Cameras and The Reconstruction of Space Models

摘要

In this paper a new mathematical model is developed for the determination of the orientation parameters of a non-metric camera using at least five control points, among which four points are coplanar, while the fifth point should lie outside that plane. In case two images of the same space model, taken at different locations by the same camera, are given, the space model can be directly reconstructed without calculating the parameters. The methods used here are direct and simple. They need no linearization of equations nor complicated techniques.
