Abstract
The invention provides a camera switching control method and device based on football detection and tracking. The panoramic camera can continue to shoot when the football is blocked by the player; it can also intercept shots from the panoramic camera based on the number of moving targets in the current video content. , and zoom the lens to the output standard picture for shooting; and the camera can be preset at the trigger position, and when the football position coincides with the trigger position, switch the camera corresponding to the trigger position to shoot. Therefore, the present invention can switch different camera lenses according to the position of the football, and complete the game video shooting on the football field under the unattended situation, which can better meet the needs of the fans when watching the game.
Description
technical field [0001] The invention relates to the technical field of camera switching control, in particular to a camera switching control method and device based on football detection and tracking. Background technique [0002] With the progress of society, the improvement of human science and technology, and the improvement of people's living standards, in order to meet the needs of unattended football field game video shooting, the level of camera switching control based on football detection and tracking should also be improved accordingly. Most of the existing cameras need to be manually controlled, and cannot automatically follow the moving target to shoot. This is a problem in the shooting of football games. On the one hand, manual shooting brings a lot of labor costs. On the other hand, manual Operation is also prone to human error. Therefore, how to realize unattended shooting of football games has aroused people's widespread concern. If the camera can be made to...
