With high-speed network and high performance PCs, live broadcasting camera systems which allow users to look at states of children in a child-care facility have become popular. In conventional systems, a user controls a PTZ camera and can look at the direction of user's requirement with high resolution. However, a user is constrained to wait for the control when multiple users access to the system simultaneously. In this study, we aim at realizing a system which can show live videos which satisfy requests of users when multiple users access to the system simultaneously. We define an evaluation function which means user's satisfaction based on a result of a questionnaire. Our method assigns each user to a camera that maximizes the evaluation function. Then, the method controls multiple PTZ cameras by optimization of camera parameters to maximize the sum of the evaluation values of users' satisfaction. In an experiment of camera control, we show the validity of our method by quantitatively evaluating the video generated from a simulated environment and an experiment in a real environment. |
