摘要：A path and/or orientation of object approaching an athlete is tracked using twoor more cameras. At least two sets of video images of the object are obtained using atleast two different cameras having different positions. Motion regions within video
images are identified, and candidate locations in 2D space of the object is/are identifiedwithin the motion region(s). Based thereon, a probable location in 3D space of theidentifiable portion is identified, for each of a plurality of instants during which the objectwas approaching. A piecewise 3D trajectory of at least the identifiable portion of theobject is approximated from the probable locations in 3D space of the object for multipleinstants during which the object was approaching the athlete. A graphical representationof the 3D trajectory of the object is incorporated into at least one of the sets of videoimages.
