Abstract [en]

This report introduces some simplications to the method by Fitzgibbon et al. that allows for 3D model construction from turn-table sequences. It is assumed that the reader has previously read in order to fully understand this report.

Fitzgibbon et al. presents a method for 3D model construction that utilizes the extra constraints imposed by turn-table sequences. Restricting the scenario to a turn-table sequence with a single camera with xed settings produces these extra constraints:

C1. The internal parameters for the camera are the same for all images

C2. The motion of the camera can be described by a rotation around a singleaxis

It is shown that in the uncalibrated case the number of parameters to estimate is m + 8 where m is the number of images.

We further simplify the problem by using extra constrains given from the fact that we know:

C3. The internal parameters of the camera, i.e the K matrix

C4. That the angle between each pair of consecutive cameras is the same

Using these extra simplications makes it possible to create a 3D model from realistic data without using Bundle Adjustment.
