Abstract

The invention provides a multimedia interaction teaching system and teaching method. The system comprises a data collection module for collecting video streams, and is characterized in that an image matting module, an image synthesis module and an image transmission and real-time display module are further included, the image matting module is used for processing the collected video streams, extracting a moving object of interest and obtaining a foreground image, the image synthesis module is used for displaying the obtained foreground image at the forefront ends of all windows in a special-shaped window mode, and the image transmission and real-time display module is used for transmitting a special-shaped window, including the synthesized image, on a teacher machine to a student machine and displaying the special-shaped window in real time. According to the system, a teacher teaching picture is obtained through a camera, and transmitted to the image matting module in real time through the network to extract the foreground figure image, the extracted foreground figure image and courseware played on the teacher machine are overlapped in a special-shaped window mode through the image synthesis module, real-time display is carried out in the teacher machine, meanwhile, the synthesized image is transmitted to the student machine in real time through the network in the mode of the video streams, and a teacher goes deep into a computer.

Description

technical field [0001] The invention relates to the field of multimedia teaching, in particular to a multimedia interactive teaching system and teaching method. Background technique [0002] Multimedia is the embodiment of informatization and the trend of social development. The level of informatization has become an important criterion for measuring a country's modernization level and comprehensive national strength. Multimedia education is a part of informatization. Vigorously promoting multimedia education has become the trend of educational development. . [0003] The use of multimedia technology in teaching is conducive to improving the professional level of teachers and helping teachers to integrate teaching resources. Multimedia teaching technology can make up for the deficiencies in traditional teaching, and it is a new type of science teaching technology. [0004] Although most of the existing multimedia teaching systems are relatively complete in terms of functio...
