大四毕业时做毕业设计,用到了百度云人脸识别的API,当时制作了一个demo发到Bilibli上,之后不少同学来问我,于是制作了一个利用虹软SDK的人脸识别的包含人脸库管理的一套服务,一年半来有不少朋友前来咨询人脸识别相关的问题,由于博主本人工作业务不涉及这部分,所以一直无心研究。最近北京疫情在家有了一些时间,利用了几天时间完善了基于虹软的代码。
首先说明一下上个版本的缺陷是什么,首先之前的人脸数据缓存在了Redis当中,当我们解析出特征值时,将数据缓存到redis中,进行逐个必对和判断,**优化的方式也只是单纯的利用多线程和虹软的人基本特征(性别、年龄)**等进行分库,几百个人脸时还好,在上千个人脸时就会出现非常明显的延迟,用户体验效率非常低,因此基于上个版本只满足部分同学的毕业设计、小组作业的场景。偶然在工作中了解到了向量搜索引擎,于是考虑是否可以结合虹软的人脸识别SDK提取特征向量,然后进行分析处理。由于这个demo主要是搭建一个大规模人脸搜索和识别服务的demo,因此没有工程化,系统设计的也比较冗余,没有详细的功能设计,基本是博主想到什么做什么。最后跪求一个 STAR 重要的事情说三遍 STAR STAR STAR
系统功能模块较为简单,主要功能就是新增人脸和人脸搜索两个功能,其中新增人脸使用页面上传和压缩包批量上传两个方式,压缩包上传时文件名称为用户名,下面主要说明人脸搜索的功能流程
在介绍前需要说明一下Mulvus
Milvus 向量数据库能够帮助用户轻松应对海量非结构化数据(图片 / 视频 / 语音 / 文本)检索。单节点 Milvus 可以在秒内完成十亿级的向量搜索
因此虹软的SDK只能提取向量及对比的功能,在大规模人脸识别中,需要搜索引擎对于人脸数据进行初步筛选到一个较小的范围后在利用虹软的SDK进行测试,值得一提的是,博主多次测试后Milvues返回的匹配率足以满足人脸匹配的要求,Milvus的安装部署和使用文档参考 https://milvus.io/cn/docs/v2.0.x
特别说明的是虹软提取的数组是一个经过归一后的1032长度的byte数组,我们需要对数组进行转换,去除前8位的版本号,并将1024长度的byte转为256长度的float向量,这部分可以利用Arrays提供的方法进行转换,代码中也有相应的工具类
批量上传采用本地打包压缩上传到服务器,后台进程进行解压,放到队列中处理,处理结果存储在ES数据库中,实时结果及处理进度通过Websocket发送至前台
前端使用了Vue admin temlate 及 Element UI
后端框架主要是SpringBoot
- mysql:存储用户信息,所有的数据以Mysql数据为准
- Elasticsearch:由于批量上传操作是异步的,用ES来收集日志并分析热点数据、成功数据、失败数据(当前版本未实现)
- InfluxDB:用于涉及到数据源较多,事务处理过于麻烦,架构设计中以Mysql中的数据为准,以Mysql数据进行数据同步
- 阿里云OSS:负责存储裁切后的人脸照片,负责前台展示及缓存失效时重新加载
- Milvues:项目的核心数据库向量搜索引擎
- ActiveMq:由于大规模人脸搜索服务需要大量的照片,一个个手动上传不现实,因此开发了批量上传的功能,需要ActiveMq进行异步上传
- restful:前后端交互主要使用restful接口
- websocket:负责将后端处理照片的过程及照片实时显示在前端
-
.env.development 文件配置后端交互地址,只需要修改所有的IP+端口 其他路径不要改变
# just a flag ENV = 'development' # base api VUE_APP_BASE_API = 'http://127.0.0.1:8080/' #VUE_APP_BASE_API = 'http://120.48.10.164:8080/' # uploadFile VUE_APP_BASE_API_UPFILE = 'http://127.0.0.1:8080/file/getImageUrl' VUE_APP_BASE_API_UPFILE_LIST = 'http://127.0.0.1:8080/file/getListImageUrl' VUE_APP_BASE_API_WEBSOCKET = 'ws://127.0.0.1:8080/api/pushMessage/' VUE_APP_BASE_API_UPFILE = 'http://120.48.10.164:8080/file/getImageUrl' #VUE_APP_BASE_API_UPFILE_LIST = 'http://120.48.10.164:8080/file/getListImageUrl' #VUE_APP_BASE_API_WEBSOCKET = 'ws://120.48.10.164:8080/api/pushMessage/'
VUE_APP_BASE_API:后端服务接口
VUE_APP_BASE_API_UPFILE:单个文件上传地址
VUE_APP_BASE_API_UPFILE_LIST:文件列表上传地址
VUE_APP_BASE_API_WEBSOCKET:Websocket地址
-
运行
npm install npm run dev 服务端口:ip:9528
- application.yml 主要是服务地址
- 修改Redis配置
- 修改Mysql配置
- 修改ActiveMq配置
- 修改Milvues配置
- 修改阿里云对象存储地址
- uploadFile配置本地缓存路径,主要是压缩包上传时需要用到
- FaceEngineConfig 类
- 配置虹软SDK的APID、SK,引擎地址
- mysql
- redis
- activeMq
- Elasticsearch(此版本不用安装)
- InfluxDB(此版本不用安装)
- Milvus
- 执行face.sql
- 利用python脚本自行爬取
