Optimized Camera Viewpoint Determination System for Soccer Game Broadcasting

In this paper, a new method for deter~niriing an optimized caniera viewpoint for soccer scene by tracking a ball is proposed. Soccer scene is taken by multiple fixed cameras. First, template matching is irnplemented for images taken with each camera to detect arid to track a ball. If the ball is occluded in one of images, tlie ball is tracked by using the position of the extracted ball in other camera. After the detection of the ball is done for all images, information of each ball position are integrated by using the geometrical relationship betweeri calrieras that, is represented by Fundamental Matrix. For deterrrii~iing t he opt i~iiizetl camcra vicwpoirit, we define a11 cvalliation function of camera selection based on the trajectory of the ball. 'I'he system selects camem viewpoint of rnch frturie al~to~riatically 11y finding tlie camera tliirt gives ~naxi~iium eval~iation of camcra sclcction. Experimental results dernoiistrate that the optimized viewpoint is successfully selected for soccer scene by using the proposed system.
