Abstract: An autonomous camera system is proposed for generating a video of a sporting event. The system comprising at least one camera, such as a wide-angle camera, is configured to capture at least a part of a playing field and output a raw video stream of the video captured. A video analyzer is configured to recognize and track an activity on the playing field by analyzing the raw video stream and to derive one or more parameters from the tracking of the activity to obtain parameter data. A parameter analyzer is configured to filter the parameter data based on one or more predefined computational rules to obtain selection data indicative of one or more regions of interest on the playing field or in the raw video stream. The regions of interest may be used to control one or more controllable cameras at the playing field or generate a video summary.
