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.
