    摘要:

    提出了一種基于嵌入式技術(shù)的蛋雞養(yǎng)殖場網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)設(shè)計(jì)方案。在嵌入式終端上搭建Linux操作系統(tǒng)環(huán)境,，并行處理視頻和圖像：通過H.264編碼對(duì)基于V4L采集的視頻進(jìn)行壓縮,，并通過RTP/RTCP和UDP協(xié)議將視頻傳輸?shù)奖O(jiān)控平臺(tái)上進(jìn)行解碼和顯示,；同時(shí)采用Ohta閾值對(duì)幀拼接的圖像進(jìn)行二值化,，獲取距離圖像,，以雞蛋半徑為閾值再次進(jìn)行二值化并對(duì)雞蛋計(jì)數(shù),，通過OSD技術(shù)將雞蛋總數(shù)疊加到視頻上?，F(xiàn)場試驗(yàn)表明,，監(jiān)控平臺(tái)上實(shí)時(shí)顯示的視頻清晰,，雞蛋計(jì)數(shù)平均準(zhǔn)確率為96.07%。

    Abstract:

    A network video surveillance system for laying hens farm was designed based on embedded technology. Linux operation system environment was built. Video and image were processed in parallel on embedded terminal: videos captured by V4L were coded based on H.264, transmitted to surveillance platform using RTP/RTCP and UDP, decoded and displayed on surveillance platform. An image from frames splice according to their contents was binarized by Ohta, converted into a distance image, binarized again with a threshold of egg radius to count eggs, and the total number was overprinted on video by OSD. Field experiment showed that videos were displayed real-timely and clearly and eggs were counted with an average accuracy of 96.07% on surveillance platform.
