摘要
一种基于嵌入式Internet的,采用DSP和ARM的独立双核结构的微格教学系统。视频跟踪中,采用具有预测功能的卡尔曼滤波器算法,设计了一种具有鲁棒性的改进型PID控制器,由DSP系统对信息进行压缩编码,再将处理好的图像编码传送给ARM系统,ARM系统将DSP传来的压缩编码通过网络协议栈打包,然后按需求通过网关发送。该系统能把上课时的视频、音频、操作过程、电脑屏幕信息等相关环境信息同步实时地记录下来,既可以通过网络实时广播,也可以数字媒体的形式存储保存下来。
One kind based on embedded Internet. uses DSP and the ARM independent binuclear structure micro standard teaching system. In the video frequency track, uses Kalman filter algorithm which has the forecast function, designed one kind advauced version PID controller which has the robust, compress code by the DSP system to the information, then transmitt the image coding to the ARM system, the ARM system the pack the compression code through the network protocol stack, then transmission t brough gatewayaceording to demand. This system can attend video frequency, audio frequency, the operating process, correlation environmental information synchronizations and so on computer screen information real-time records, also may through the network real-time broadcast, and preserve the memory as digital media form.
