Embodiment Construction

[0027] Such as figure 1 As shown, a dual-camera interactive intelligent tracking teaching system of the present invention consists of 8 modules: an image acquisition module, a camera control module, a user interface interaction module, a thread interaction module, a teacher tracking module, a student detection module, and a student tracking module.

[0028] The overall implementation process is as follows:

[0029] (1) System initialization parameter setting unit. In the process of actual installation and use, according to the size of different classrooms, the installation positions of the teacher’s camera and the student’s camera will be different. Through the system initialization parameter setting, the ceiling height and inclination angle of the camera can be obtained when the camera is installed. For a good tracking and detection effect, it is often necessary to set the initial preset position of the teacher's camera according to the actual situation; for the input teache...

Abstract

The invention discloses a double video camera interactive intelligent tracking teaching system. The double video camera interactive intelligent tracking teaching system comprises an image collecting module, a video camera control module, a user interface interaction module, a thread interaction module, a teacher tracking module, a student testing module and a student tracking module. During the teaching process, a control main engine obtains images which are photographed by teachers and students in real time through a dual image acquisition card. A tracing algorithm and a detecting algorithm based on an image processing technique are used for calculating the results and choosing appropriate control strategies. Mutual change among signals are reasonably arranged, functions of the live video camera including swaying, pitching, zooming and focusing can be rapidly, flexibly and accurately achieved. Teachers are capable of locating a proper position in the shooting picture, and functions like teachers' automatic tracing and positioning, students' video mapping and offering a close-up view while questioning testing and writing on the blackboard are achieved. In the end, the automatic intelligent tracing teaching system of tracing the external disturbance, no specific behavior limits and shooting without specially-assigned person on guard is achieved.

Description

technical field [0001] The invention relates to an interactive intelligent tracking teaching system combined with image acquisition, moving target detection and tracking, camera control and other technologies, belonging to the technical field of computer vision teaching. Background technique [0002] Inspired by the rural distance project vigorously promoted by the Ministry of Education, relying on the rapid development of modern Internet technology, including the change of learning methods, the unprecedented development and application of E-learning technology, the increasing popularity of online teaching, etc., in recent years, the intelligent tracking teaching system has gradually It has been promoted in the classroom teaching of various primary and secondary schools in my country and has become one of the main forms of teaching skills training. With the rapid development of object tracking technology research in image processing and computer vision theory in recent years,...
