Jetson Nano 安裝Opencv3.4.0 + Opencv3.4.0_contrib

由于要複現的代碼必須要求opencv3，而闆子自帶的鏡像JetPack中是opencv4.1.1,把opencv4.1.1解除安裝之後，又自帶的是opencv3.2.0。

參考連結：安裝opencv4.1.0的：https://blog.csdn.net/long19960208/article/details/89448106其中過程做了一點修改,且更詳細

1. 首先下載下傳opencv+opencv_contrib,這裡這篇部落格給出的百度雲連結：

2. 可以用PanDownload下載下傳這兩個檔案 然後解壓到你的檔案夾裡，假設是：/home/opencv
3. cd /home/opencv
4. touch install_opencv3.4.0_Nano.sh #建立sh檔案
5. gedit install_opencv3.4.0_Nano.sh #打開空檔案
6. 粘貼以下：

make -j3
sudo make install
sudo apt-get install -y python-opencv python3-opencv
 
echo "** Install opencv-3.4.0 successfully"

           

1. 打開指令行，輸入：

sh  install_opencv3.4.0_Nano.sh /home/opencv
           

安裝中遇到的問題

1. tiny-dnn下載下傳不下來

   由于一直存在的問題：在github下載下傳東西賊慢，是以總會使得下載下傳逾時，這裡給一個超級快的加速網站： https://wjx.wiki/service/accelerator/index

再将下載下傳好的檔案替換掉opencv檔案夾裡面的.cahce（查找一下就好啦）中的tiny_dnn的壓縮包，注意原本.cahce中的tiny_dnn不叫這個名字，而是一長串的英文字母，把下載下傳好的tiny_dnn放進這個檔案夾後，要把名字修改成那原本的一長串英文字母。

1. 同理face_landmake.dat也是一樣的情況，采取1中的辦法。
2. 使用make-j16會使闆子直接卡死，慎用！
