Double video camera interactive intelligent tracking teaching system

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.
