Abstract
An object is detected in images of a live event by storing and indexing camera registration-related data from previous images. For example, the object may be a vehicle which repeatedly traverses a course. A first set of images of the live event is captured when the object is at different locations in the live event. The camera registration-related data for each image is obtained and stored. When the object again traverses the course, for each location, the stored camera registration-related data which is indexed to the location can be retrieved for use in estimating a position of a representation of the object in a current image, such as by defining a search area in the image. An actual position of the object in the image is determined, in response to which the camera registration-related data may be updated, such as for use in a subsequent traversal of the course.
