Patent Images
1. A camera tracking apparatus comprising:
- a sequence image input unit configured to obtain one or more image frames by decoding an input two-dimensional image;
a two-dimensional feature point tracking unit configured to obtain a feature point track by extracting feature points from each of the image frames obtained by the sequence image input unit, and by comparing the extracted feature points with feature points extracted from a previous image frame to connect feature points that are determined to be similar; and
a three-dimensional reconstruction unit configured to reconstruct the feature point track obtained by the two-dimensional feature point tracking unit.

Abstract
A camera tracking apparatus including a sequence image input unit configured to obtain one or more image frames by decoding an input two-dimensional image, a two-dimensional feature point tracking unit configured to obtain a feature point track by extracting feature points from respective image frames obtained by the sequence image input unit, and comparing the extracted feature points with feature points extracted from a previous image frame, to connect feature points determined to be similar, and a three-dimensional reconstruction unit configured to reconstruct the feature point track obtained by the two-dimensional feature point tracking unit.
