METHOD AND APPARATUS FOR CAMERA TRACKING

摘要

PURPOSE: A method and an apparatus for tracing the location of a camera are provided to trace first features within multiple frames and to trace second features within a single frame based on the traced first features. CONSTITUTION: A feature extracting unit extracts third features from at least three images in a first frame among multiple frames (410). A feature tracing unit traces the extracted third features to the last frame among the multiple frames (420). A dynamic point detector removes features having a dynamic trace among the traced third features and determines first features (430). A camera location estimating unit estimates the location of each camera within each frame based on the first features (440). [Reference numerals] (410) Extract features from a first frame among multiple frames; (420) Trace the extracted features to the last frame among the multiple frames; (430) Remove features having a dynamic trace among the traced features; (440) Estimate the location of each camera based on remaining features after the removal; (AA) Start; (BB) End
