可能出现的错误
如果第一步dpkg就出现如下错误：
(Reading database ... 142818 files and directories currently installed.)
Preparing to unpack cuda-repo-l4t-r21.3-6-5-prod_6.5-42_armhf.deb ...

安装OpenCV4tegra

安装OpenCV2.4.10
下载链接 opencv2.4.10
安装依赖库/解压/编译/安装/配置环境变量都参考链接http://blog.csdn.net/u012348655/article/details/50564223
可能出现的问题
如果在
openexr文件夹下有half文件夹，half文件夹下的half.h文件有对上述几个变量或函数的定义。 
- sudo make -j4 install
运行后出现问题
Linking CXX executable ../../bin/opencv_createsamples
Linking CXX executable ../../bin/opencv_performance
Linking CXX executable ../../bin/opencv_haartraining
../../lib/libopencv_highgui.so.2.4.10: undefined reference to `half::_eLut'
../../lib/libopencv_highgui.so.2.4.10: undefined reference to `half::_toFloat'
../../lib/libopencv_highgui.so.2.4.10: undefined reference to `half::convert(int)'openexr文件夹下有half文件夹，half文件夹下的half.h文件有对上述几个变量或函数的定义。
在网上搜索TK1下安装opencv2.4.10时，发现两篇和opencv在arm-linux下交叉编译有关的博客

参考这两篇发现需要可以在cmake-gui界面下关闭openexr，尝试关闭生成新的cmakefile后，make install成功了

如果没有cmake-gui需要先安装
在超级用户模式下进入cmake-gui
ubuntu@tegra-ubuntu:~/opencv-2.4.10/build$ sudo su
[sudo] password for ubuntu:
root@tegra-ubuntu:/home/ubuntu/opencv-2.4.10/build# cmake-gui
安装QT creater
安装与配置方法同参考链接http://blog.csdn.net/u012348655/article/details/50564223
安装ROS
安装方法同官方 ROS-WIKI
安装OSDK
安装方法 同官方DJI-OSDK文档
