Rock-X SDK是什么？怎样去编译Rock-X SDK呢

一、简介
Rock-X SDK 是基于 RK3399Pro/RK180X 等平台的一套 AI 组件库。开发者通过 Rock-X SDK 提供的 API 接口能够快速构建 AI 应用。
Rock-X SDK 当前支持 Python/C 编程语言, 支持运行于 RK3399Pro Android/Linux 平台、RK180X Linux 平台以及 PC Linux/MacOS/Windows(需要接 RK1808 计算棒)。
本文测试基于RV1109或RV1126的buildroot系统中，运行rock-x sdk。
SDK 提供的功能如下：

二、编译Rock-X SDK
使用RK_SDK_rv1126_rv1109_linux SDK
1.下载编译CMake
rockx sdk的编译需要基于 3.10 以上版本的cmake， 如果系统的cmake版本比较旧，则需要更新cmake。
$ sudo apt-get install build-essential
$ cd ~/Download/
$ wget
$ tar -zxvf cmake-3.11.3.tar.gz
$ cd cmake-3.11.3
$ ./configure
$ make
# $ sudo make install
$ ~/Downloads/cmake-3.11.3/bin/cmake -version
cmake version 3.11.3
CMake suite maintained and supported by Kitware (kitware.com/cmake).
为了不应用系统已安装的cmake，可以不使用install。
2.修改编译环境
修改 external/rockx/demo/command_line_demo/build-linux-rv1109.sh
修改交叉编译工具链路径
修改cmake路径
手动编译
cd external/rockx/demo/command_line_demo
git diff build-linux-rv1109.sh
diff --git a/demo/command_line_demo/build-linux-rv1109.sh b/demo/command_line_demo/build-linux-rv1109.sh

3.配置编译rockx
$ cd external/rockx/demo/command_line_demo
# 配置编译环境
$ bash build-linux-rv1109.sh
rockx_demo

三、在buildroot系统中运行rockx
1.复制编译结果和依赖文件到本地
将主机的编译结果和动态库等文件拷贝到RV1109或RV1126设备中
$ cd external/rockx/
$ scp -r sdk/ root@xxx:/userdata/rockx
$ scp -r demo/command_line_demo/ root@xxx:/userdata/rockx
2.加入动态链接库新搜索路径
# RV1109设备上
cd /userdata/rockx
# 将动态库和头文件放到与AI模型同一路径下
cp sdk/rockx-rv1109-Linux/lib/* sdk/rockx-data-rv1109/
cp sdk/rockx-rv1109-Linux/include/ sdk/rockx-data-rv1109/
# 修改环境变量
vi /etc/profile
# 加入
ROCKX_DATA_PATH=/userdata/rockx/sdk/rockx-data-rv1109
export LD_LIBRARY_PATH=${ROCKX_DATA_PATH}:$LD_LIBRARY_PATH
source /etc/profile
也可以直接把动态库和AI模型复制到系统路径
cp sdk/rockx-rv1109-Linux/lib/* /usr/lib/
cp sdk/rockx-rv1109-Linux/include/ /usr/lib/
cp sdk/rockx-data-rv1109/ /usr/lib/
3.运行rockx demo 可执行文件
$ cd /userdata/rockx/command_line_demo/build/build_rv1109_linux/rockx_carplate_demo
# 运行车牌识别程序
$ ./rockx_carplate ../../../rockx_carplate_demo/carplate_det_test1.jpg
