This paper describes and compares two slightly different methods for “real-time” visualization of panoramic stadium tribune images in high resolution using a virtual camera. The methods are tested as a part of the novel automatic panoramic surveillance camera system for the protection of people and property at sports stadiums. In the following sections, we introduce and compare our two methods, which are tested with four industrial 4k cameras. The first method processes input video streams composed of already transformed images and most of the operations are done on the CPU. The second method processes original video streams from cameras and specific operations are done on the GPU. Using our two methods and specific PC configuration, it is possible to display a full resolution panoramic video sequence with a maximal frame rate of 11.68 ± 2.11 fps and 6.82 ± 1.86 fps. Focusing on a real-time application, more experimental results with the computational efficiency of particular stages in our methods are presented and discussed.
