Description
Technical field
The present invention has and chases after vertical system and method about a kind of intelligent image, especially provides operator conveniently to chase after vertical specific objective.
Background technology
Usually, there is provided many people to participate in and the large-scale meeting-place of discussing simultaneously, in order to meeting-place safely, save or deposit the object of card from damage, need to configure multiple video camera and carry out live video and monitoring, scene need configure specifically monitored personnel with the running of control equipment equipment simultaneously, also image can be transmitted long-range server, carry out data backup, and for long-range personnel's reference.
The shareholders' meeting that more people is participated in, seminar, forum, press conference, product presentations, in many ways video conference, because every spokesman has suitable importance, therefore, for really taking useful picture, especially carry out the participant made a speech, usually need the photography team of specialty to carry out live video.General operation mode is, the image of diverse location is taken by several photographer, and image is sent to record control main frame, passed back multiple images are inspected through the screen of record control main frame by instructor in broadcasting, and the on-the-spot needs of foundation and professional judgement are with choice of dynamical image, and then commander operating personnel or in person operation record control main frame, to record a video.
Moreover attend class video recording in the scene for remote teaching, often because course needs or in order to increase teaching efficiency, teacher and student must at school period interactive, such as asked a question by teacher, and specify a certain learner answering questions, or by from high learner answering questions courageously.Now, the distance of taking lens need adjust at any time, focus, and video frames repeatedly must switch between teacher and different student, therefore more needs the instructor in broadcasting of specialty just can complete the visual and sound effects of tool teaching when participating in the cintest.
But above-mentioned video recording mode is labor intensive and computer hardware resource too, and not only operation easier is high, and integrated operation cost is quite high, many occasions in need cannot be applied to widely.Therefore, in the prior art, normal utilization has can take different angles and the video camera of size of finding a view through Long-distance Control, such as PTZ camera (Pan/Tilt/ZoomCamera), use the required picture of dynamically shooting, and be equipped with the special photograph machine with ultra-wide angle degree coverage at the scene, such as panoramic camera (PanoramicCamera) simultaneously, to take whole on-the-spot scenery, be used as reference picture.Therefore, the number of photography scene teacher can be reduced, and control all PTZ camera by minority operating personnel, and switch the filmed image of PTZ camera through instructor in broadcasting, choose best video frames, and complete overall video recording work, really can reduce running cost.
But the shortcoming of above-mentioned prior art is still to need full-time instructor in broadcasting to choose and controls the image of video recording, and PTZ camera still needs special messenger to control, and cannot further reduce manpower and running cost.Therefore, be sought after a kind of intelligent image and chase after vertical system and method, can not need under instructor in broadcasting personnel and video camera operating personnel, allow the convenient overall image that controls of user chase after vertical operation, realize image and chase after vertical, video recording, use the problem solving above-mentioned prior art.
Summary of the invention
