本文來(lái)源電子發(fā)燒友社區(qū)，作者：大菠蘿Alpha， 帖子地址：https://bbs.elecfans.com/jishu_2309330_1_1.html


前面文章已經(jīng)在Ubuntu20.04的系統(tǒng)上搭建交叉編譯環(huán)境，并且在EASY EAI Nano開(kāi)發(fā)板上執(zhí)行了第一個(gè)程序。

一、下載源碼

使用git工具，將遠(yuǎn)程倉(cāng)庫(kù)clone至本地：

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

toolkit內(nèi)置好幾個(gè)AI案例，選擇solu-helmetDetect。

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、編譯源碼

開(kāi)發(fā)環(huán)境中執(zhí)行./build.sh，過(guò)程&結(jié)果如下圖：

在Release目錄下生成了solu-helmetDetect可執(zhí)行程序。

三、上傳

需要上傳2個(gè)文件，一個(gè)是前面生成的solu-helmetDetect文件，還有一個(gè)是官方提供的模型文件helmet_detect.model。

四、測(cè)試運(yùn)行

在EASY EAI Nano開(kāi)發(fā)板上執(zhí)行./solu-helmetDetect。

[root@EASY-EAI-NANO:/userdata/Solu]# chmod 777 solu-helmetDetect
[root@EASY-EAI-NANO:/userdata/Solu]# ./solu-helmetDetect

因?yàn)闆](méi)有安全帽，網(wǎng)絡(luò)上找了個(gè)戴安全帽的照片，哈哈：）

檢測(cè)到安全帽：

沒(méi)有帶安全帽：
