虹软人脸检测SDK

LICENSE Supported platform Build Status GoDoc

基于虹软SDK V3

目前已适配的版本： v2.2.0 v3.0.0

开始使用

  • 安装方式一（不使用go mod）：go get -d github.com/windosx/face-engine
  • 安装方式二（使用go mod）：go get github.com/windosx/face-engine/v3
  • 编译：go build -o test github.com/windosx/face-engine/v3/cmd
  • 测试：./test
  • 库文件：Linux下将libarcsoft_face.so, libarcsoft_face_engine.so放入/usr/lib目录
  • Windows下将libarcsoft_face.dll, libarcsoft_face_engine.dll放入%WINDIR%/System32目录或执行文件同目录下
  • 编译环境依赖GCC Linux环境下编译需要先安装gcc，Windows下编译需要先安装MinGW-w64（32位下用mingw），并将libarcsoft_face.dll, libarcsoft_face_engine.dll放入MingGW-w64安装目录下的lib目录中
