Abstract
The invention relates to a scene interaction type multimedia system. The scene interaction type multimedia system comprises a server and interaction terminals. In design, the scene interaction type multimedia system is characterized in that the interaction terminals comprise processors and writing show platforms, and the processors send audio and video data acquired from camera devices to the server through communication modules; the camera devices are two cameras which can shoot the writing show platforms and a site environment with a user in a stereoscopic and alternative mode, the first camera shoots character information content on the corresponding writing show platform in real time in a downward direct facing mode, and the second camera can shoot and acquire information of the corresponding writing show platform area and videos or images of the site environment with the upper part of the user in real time; the interaction terminals acquire the videos shot by the camera devices from the server and display the videos through displayers of the interaction terminals. According to the scene interaction type multimedia system and the application of the scene interaction type multimedia system, mutual restoration of a student scene and a teacher scene is really achieved through stereoscopic shooting of regional space where the multimedia intelligent terminals are located.
Description
[technical field]
The present invention relates to teaching equipment, what be specifically related to is a kind of scene interaction formula multimedia system and application thereof, and it can be applied to, and long-range scene interaction formula multimedia teaches teaching, long-range scene interaction formula multimedia exchanges, long-range scene interaction formula multimedia helps each other study, long-range scene interaction formula multimedia training etc.
[background technology]
Current teacher attends class to student and interchange between teachers and students, generally carries out by the mode face-to-face such as classroom being lectured.The audio-visual education programme grown up for nearly ten years and the teaching of class material etc., just get off content recordal such as resources material and phonetic teaching such as teaching material teaching materials by means of some electric equipments, helps students ' reading, cultivates and pay attention to the class ability and review.Along with the development of network, utilize internet to carry out remote teaching and progressively popularized, people can pass through Network Capture knowledge, do not use school sessions; Meanwhile, instructional blocks of time is also relatively freer, and student can listen to the teacher the time according to the arrangement of time of oneself, need not attend class according to the time of regulation.In addition, the content of courses also can be recorded once and just be put things right once and for all by teacher, only instructional video need be put in server and be accessed by student.
But existing internet teaching system, does not have interaction function, teachers and students cannot be allowed to carry out interaction, and student can only listen to the teacher in terminal, also cannot put question to even if having a question.Moreover, existing system only has a camera shooting and an interface display usually, although a camera energy collection site sight, but the scene of camera collection is generally the scene with user and surrounding environment, its information gathered is too abstract, such as camera only photographs student or teacher's molar behavior, or projector displaying contents, but cannot show best image quality to the activities of student or teacher, expression.Because each camera focal length is different, reference object is varied in size, when at reference object, whole teaching environment position is different, light is different, the way of single camera collection scene is adopted to be difficult to the requirement of local high definition display effect when meeting interactive teaching, and adopt single camera to be also difficult to multiple partial result to take display simultaneously, even if camera angle can be adjusted, also can only the picture taken of single display, inconveniently in an environment, gather diverse location high-definition image.Therefore, be necessary to improve existing scene interaction formula multi-medium intelligent terminal, make it have shooting interface, multiple local, take display respectively for diverse location under same environment simultaneously, really realize the technique effect of student, the on-the-spot reduction mutually of teacher.
Be badly in need of except improvement to the image acquisition of reducing mutually except scene in internet teaching, also there is a realistic problem being badly in need of solving in existing interaction teaching device terminal: popularizing of computing machine, internet brings great convenience to us, the propagation accelerating information with exchange, also bring some bad impacts: such as computer typewriter simultaneously, cause fuzzy to font typeface of people, long-time computer typewriter makes personal letter writing of Chinese characters difficulty, and the word be many times familiar with but can not be write out.For this reason, when providing scene interaction formula multi-medium intelligent terminal, the teaching of tempering manipulative ability is also mixed multi-medium intelligent terminal by the applicant, to make between student, teacher or between kith and kin in On-the-spot Interaction process real time inspection personal letter write, the manipulative ability such as drawing, avoid the shortcoming too relying on machine operation to bring.
[summary of the invention]
Goal of the invention is to provide a kind of scene interaction formula multimedia system and application thereof, it can realize a multiple on-link mode (OLM) of teaching appliance, brand-new relation among teaching can be set up, to the stereoscopic shooting in space, multi-medium intelligent terminal region during use, really realize student, the on-the-spot reduction mutually of teacher, easy to use.
