Abstract

A real-time video surveillance system for piggery was designed to overcome the disadvantages of traditional observation methods for behavior of pigs. In this system, embedded system technology, H.264 video encoding technology and network communication technology were combined for real-time monitoring the behavior of pigs. According to directional centre-biased motion vector distribution and the characteristic that the motion in the horizontal direction is more impetuous than vertical direction in the surveillance video for piggery, thin diamond search (TDS) algorithm was proposed in this paper. The algorithm is based on thin diamond search pattern, and has the feature of fast speed while maintaining high precision of diamond search algorithm. The experimental results showed that the computation complexity and coding time of video coding are reduced in the TDS algorithm, so that the real-time performance of the surveillance video was improved significantly. This study provides a convenient way and low-cost method for remote monitoring of animal behavior. Therefore, the system has a wide application prospect in intelligent precision breeding industry.

基于H.264和嵌入式系统的猪舍实时视频监控系统

为了克服传统猪场行为观察方法的不足，设计了猪场实时视频监控系统。本系统结合嵌入式系统技术、H.264视频编码技术和网络通信技术，实现了猪的行为实时监控。根据猪舍监控视频中运动矢量的定向中心偏置分布和水平方向运动比垂直方向运动更剧烈的特点，提出了薄菱形搜索算法(TDS)。该算法基于薄菱形搜索模式，在保持菱形搜索算法精度的同时，具有速度快的特点。实验结果表明，TDS算法降低了视频编码的计算复杂度和编码时间，从而显著提高了监控视频的实时性。本研究为动物行为的远程监测提供了一种便捷、低成本的方法。因此，该系统在智能精密养殖行业具有广阔的应用前景。
