【EASY EAI Nano开源套件试用体验】AI功能测试–头盔检测-服务器开源项目

前面文章已经在Ubuntu20.04的系统上搭建交叉编译环境，并且在EASY EAI Nano开发板上执行了第一个程序。

一、下载源码

使用git工具，将远程仓库clone至本地：

复制git clone https://github.com/EASY-EAI/EASY-EAI-Toolkit-C-Solution.git

toolkit内置好几个AI案例，选择solu-helmetDetect。

复制root@EliteDesk:/media/rv1126/EASY-EAI-Toolkit/EASY-EAI-Toolkit-C-Solution$ ls easyeai-api LICENSE README_CN.md README.md solu-EAI-box solu-faceDetect solu-faceRecognition solu-helmetDetect solu-personDetect solu-qrdecode solu-rtspMulitPlayer 二、编译源码

开发环境中执行复制./build.sh，过程&结果如下图：

在Release目录下生成了solu-helmetDetect可执行程序。

三、上传

需要上传2个文件，一个是前面生成的solu-helmetDetect文件，还有一个是官方提供的模型文件helmet_detect.model。

四、测试运行

在EASY EAI Nano开发板上执行复制./solu-helmetDetect。

复制[root@EASY-EAI-NANO:/userdata/Solu]# chmod 777 solu-helmetDetect [root@EASY-EAI-NANO:/userdata/Solu]# ./solu-helmetDetect media get entity by name: rkcif-lvds-subdev is null media get entity by name: rkcif-lite-lvds-subdev is null media get entity by name: rkisp-mpfbc-subdev is null media get entity by name: rkisp_dmapath is null media get entity by name: rkisp-mpfbc-subdev is null media get entity by name: rkisp_dmapath is null media get entity by name: rockchip-mipi-dphy-rx is null [17:30:48.060264][CAMHW]:XCAM ERROR CamHwIsp20.cpp:928: No free isp&ispp needed by fake camera!

因为没有安全帽，网络上找了个戴安全帽的照片，哈哈：）

检测到安全帽：
