一、引言

新型冠狀病毒疫情爆發(fā)以來，全球各國政府采取了一系列措施，其中包括封鎖各類人員聚集場所、限制人員出行等。而人員跟蹤系統(tǒng)則是一個(gè)更加直接有效的手段。通過對特定區(qū)域或場所內(nèi)的人員進(jìn)行跟蹤，及時(shí)發(fā)現(xiàn)并隔離疑似病例，從而遏制病毒的傳播。目前，市場上已經(jīng)出現(xiàn)了眾多的人員跟蹤系統(tǒng)，但絕大部分存在識別率低、誤報(bào)率高等諸多問題，難以滿足實(shí)際需求。

二、面向疫情防控的人員跟蹤系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)

1.需求分析

本系統(tǒng)旨在為疫情防控提供一種高效、精準(zhǔn)、可靠的人員跟蹤解決方案。具體要求如下：

（1）高精度的人臉識別技術(shù)，能夠準(zhǔn)確識別人員身份信息；

（2）穩(wěn)定的系統(tǒng)性能，能夠在高流量環(huán)境下穩(wěn)定運(yùn)行；

（3）完整的數(shù)據(jù)記錄和分析功能，包括對進(jìn)出記錄、軌跡分析等相關(guān)數(shù)據(jù)進(jìn)行管理；

2.系統(tǒng)設(shè)計(jì)

（1）系統(tǒng)整體架構(gòu)

本系統(tǒng)采用了分布式架構(gòu)，主要由前端監(jiān)控、后端處理以及數(shù)據(jù)存儲三個(gè)部分組成。其中前端監(jiān)控部分主要負(fù)責(zé)人臉采集、識別和展示等功能，后端處理部分主要完成數(shù)據(jù)推送、人臉識別和數(shù)據(jù)分析等功能，而數(shù)據(jù)存儲部分主要負(fù)責(zé)對人員信息、設(shè)備信息等相關(guān)數(shù)據(jù)的存儲和管理。

（2）系統(tǒng)核心技術(shù)

本系統(tǒng)的核心技術(shù)之一是高精度人臉識別技術(shù)。針對不同的人臉特征，系統(tǒng)采用了不同的算法進(jìn)行處理，包括基于深度神經(jīng)網(wǎng)絡(luò)的人臉識別算法、基于經(jīng)驗(yàn)分類的人臉識別算法等。通過不斷地學(xué)習(xí)和優(yōu)化，系統(tǒng)能夠獲得更高的識別率和準(zhǔn)確度。

（3）系統(tǒng)實(shí)現(xiàn)技術(shù)

為了實(shí)現(xiàn)高效精準(zhǔn)的人員跟蹤，系統(tǒng)還采用了其他多種技術(shù)。例如，通過使用圖像處理技術(shù)，系統(tǒng)可以實(shí)現(xiàn)自動(dòng)裁剪和優(yōu)化處理等功能；通過使用數(shù)據(jù)分析技術(shù)，系統(tǒng)可以完成人員軌跡和行為模式分析等功能。

3.系統(tǒng)實(shí)現(xiàn)

系統(tǒng)開發(fā)采用了現(xiàn)代的開發(fā)方法和工具，包括前端Vue、后端Python等開發(fā)語言和框架，同時(shí)還引入了眾多優(yōu)秀的開源組件，如人臉識別API、圖像處理庫等等，極大地提高了系統(tǒng)的開發(fā)效率和穩(wěn)定性。

三、實(shí)驗(yàn)結(jié)果分析

本系統(tǒng)實(shí)際運(yùn)行效果表明，該系統(tǒng)能夠精準(zhǔn)識別人員身份信息，且穩(wěn)定性較強(qiáng)。數(shù)據(jù)分析結(jié)果顯示，本系統(tǒng)能夠滿足實(shí)際需求，包括實(shí)時(shí)記錄人員進(jìn)出狀況、自動(dòng)推送預(yù)警信息、快速導(dǎo)出數(shù)據(jù)等。

四、總結(jié)與展望

本文設(shè)計(jì)和實(shí)現(xiàn)了一種面向疫情防控的人員跟蹤系統(tǒng)，采用了現(xiàn)代化的開發(fā)技術(shù)和人工智能技術(shù)。實(shí)驗(yàn)結(jié)果表明，該系統(tǒng)在精準(zhǔn)性、穩(wěn)定性和效率等方面表現(xiàn)出色。未來，我們將進(jìn)一步完善系統(tǒng)功能和對算法的更新優(yōu)化，以適應(yīng)更大范圍的應(yīng)用需求。
