基于嵌入式Web的双路远程视频同步监控方法

Dual Channel Remote Video Synchronization Monitoring Method Based on Embedded Web

为解决传统远程监控方法由于视频处理模块的构成较为复杂,导致其稳定性和扩展性较差的问题,提出一种基于嵌入式Web的双路远程视频同步监控方法。监控前端由两个摄像机组合而成,同时进行监控目标的视频图像采集工作,由FPGA模块对两个信号合并处理传送至压缩模块内。为了更有效地统一化处理图像帧内和帧间数据,采用运动补偿技术和软阈值小波变换技术融合法对视频图像数据压缩,以改进的多连接TCP/IP协议作为数据传输通道实现远程视频的同步监控。仿真结果表明,压缩后数据传输速度更快,且获得的双路监控画面效果更清晰,能够有效地实现远程同步监控。

Traditional remote monitoring methods have many defects,such as poor stability and scalability caused by the complexity of video processing module.Therefore,this paper proposes a dual channel remote video synchronization monitoring method based on Embedded Web.The monitoring front-end system was composed of two cameras to collect the video image of the monitoring target.The FPGA module was used to combine the two signals and transmit them to the compression module.The fusion method of motion compensation technology and soft threshold wavelet transform technology was adopted to compress the video image data for processing the intra frame and inter frame data more effectively.Thus,the improved multi connection TCP/IP protocol was used as the data transmission channel to achieve the synchronous monitoring of remote video frequency.Simulation results show that the compressed data have fast transmission speed,clear dual channel monitoring effect,and the proposed method can effectively realize remote synchronous monitoring.
