Method for simulating five cameras by utilizing double cameras for education recording and broadcasting

Abstract

The invention relates to a method for simulating five cameras by utilizing double cameras for education recording and broadcasting, which is applied to a campus professional live video. According to the method for simulating the five cameras by utilizing the double cameras for the education recording and broadcasting and a live broadcasting method thereof, a system of the method for simulating the five cameras by utilizing the double cameras for the education recording and broadcasting comprises a recording and broadcasting main unit, a display, a teacher camera and a student camera, wherein the teacher camera can shoot a teacher podium and a whole wall body where a blackboard is located, the student camera can shoot panorama of all the students, the recording and broadcasting main unit is used for analyzing and judging data transmitted by the two cameras, a main screen is displayed by the display. By adopting the method provided by the invention, a shooting task can be finished by utilizing only two cameras without utilizing a pan-tilt-zoom camera, and any camera can be utilized; wire arrangement is also simple by utilizing only two cameras, two video lines and two power lines.

Description

technical field [0001] The invention relates to a method for simulating five cameras with two cameras for teaching recording and broadcasting, which is used for professional video live broadcast on campus. Background technique [0002] In modern teaching recording and broadcasting, in order to capture richer picture scenes, schools often collect five camera positions to shoot. In this mode, there are many defects: the traditional technology needs to use more cameras, five cameras are needed In order to complete the shooting task, some shooting must be done with a designated camera, and the camera must be controlled by a pan / tilt during shooting. In addition, the installation and wiring are also very complicated, requiring 5 cameras + 5 video cables + 5 Power line + 5 control lines, the cost will increase significantly. [0003] Chinese invention patent publication number "103093654A" discloses "a dual-camera interactive intelligent tracking teaching system", including an im...

[0002] In modern teaching recording and broadcasting, in order to capture richer picture scenes, schools often collect five camera positions to shoot. In this mode, there are many defects: the traditional technology needs to use more cameras, five cameras are needed In order to complete the shooting task, some shooting must be done with a designated camera, and the camera must be controlled by a pan / tilt during shooting. In addition, the installation and wiring are also very complicated, requiring 5 cameras + 5 video cables + 5 Power line + 5 control lines, the cost will increase significantly

The technical solution disclosed in this patent involves many hardware modules, mainly seven modules, and introduces a user interface interaction module and a camera control module that require manual operation, and the technology used is relatively cumbersome, and some values ​​need to be preset, such as Very specific data parameters such as the height of the teacher, the size of the classroom, the position and angle of the camera, etc., all make the product not intelligent enough, which will seriously affect the user experience in actual use
