Abstract

The invention discloses an optimal tracking method and system for an automatic identification image of a remote education teacher. The method comprises the following steps of video data acquisition, target framing, foreground extraction target identification, adjustment parameter determination, video simplified compression and the like; the system comprises a video acquisition module, a storage module, a teacher target framing processing module, a foreground extraction module, a data modeling module, a pixel classification module, a teacher target generation module, a position calibration module, an adjustment parameter generation module, a video data compression processing module and a communication module. According to the method and the system, a teacher target in a video image can be accurately extracted, the acquisition angle and the direction of a video are synchronously adjusted according to the movement of the target, and the image of the teacher target can be clearly and completely acquired all the time, so that the data volume in the video transmission is reduced, the accurate effectiveness of the teacher target information is ensured, and the higher practical value and the wide application prospect are provided.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a method and system for automatically identifying image optimization and tracking for distance education teachers. Background technique [0002] With the rapid development of social economy and the rapid advancement of science and technology, people's lifestyles have changed, and remote video and video surveillance applications are becoming more and more widespread. For example, distance education, in any remote place, you can freely choose what you need to learn for learning, and another example is the video surveillance system installed in commercial plazas, supermarkets, schools and other places where public safety is more important. [0003] However, in the existing video analysis process, there are many problems in the extraction of teacher targets, such as how to effectively determine the teacher target, how to eliminate the influence of dynamic background in fo...
