Camera pose estimation

Abstract

Pose estimation is a fundamental problem in computer vision and is prevalent in numerous applications such as object-detection, tracking etc. Generally, in pose estimation between two camera views, we have 6 degrees of freedom - 3 rotational and 3 translational parameters. But in some cases, we can enforce extra constraints such as a fixed axis of rotation. We can thus frame our problem in terms of fewer parameters. In this report we discuss some of these special cases and how we can perform pose estimation better for such cases.
