Incremental Rectification of Sports Fields in Video Streams with Application to Soccer
نویسندگان
چکیده
We describe a complete system for image rectification in sport video sequences. Relying both on geometrical properties of the field elements and on photogrammetric data, we compute an estimate of the field-to-image homography either incrementally – by inter-image data processing – or “from scratch” when direct image-model correspondences are possible. Examples are given in a soccer context.

Robust incremental rectification of sports video sequences
We describe an important element of an automatic sport analysis system. This element continuously estimates the image-to-model homography from the video stream of a single camera. Here, we focus on the incremental image-to-image updating of the homography matrix, which greatly facilitates real-time operation. This updating relies on the automatic tracking of interest lines and points and on the...
