Abstract
Semantic analysis of sport sequences requires camera calibration
to obtain player and ball positions in real-world coordinates.
For court sports like tennis, the marker lines on
the field can be used to determine the calibration parameters.
We propose a real-time calibration algorithm that can
be applied to all court sports simply by exchanging the court
model. The algorithm is based on (1) a specialized courtline
detector, (2) a RANSAC-based line parameter estimation,
(3) a combinatorial optimization step to localize the
court within the set of detected line segments, and (4) an
iterative court-model tracking step. Our results show realtime
calibration of, e.g., tennis and soccer sequences with a
computation time of only about 6 ms per frame.
