surround360 step2 render
参考文章https://blog.csdn.net/dancewine/article/details/80999306将surround360在Ubuntu16.04上安装完成。
我只有12个bin，且没有Unpacker.bin文件，在后续的使用过程中，我无法进行step1的程序，不过这并不影响step2render的进行。
下载官方的sample data https://github.com/facebook/Surround360 http://surround360.hacktv.xyz/sample/sample_dataset.zip
解压后，打开如图所示
运行
cd Surround360/surround360_render/scripts
python run_all.py弹出窗口
图中各项的具体参数概念参看https://blog.csdn.net/smallflyingpig/article/details/79451890
step1 unpack 不进行
step2 render
对于render过程，Data Directory不太重要，我设定为sample_dataset/vid/000000
Destination Directory设定为一个新建文件夹，我设定为sample_dataset/output
在output文件夹中，新建一个‘rgb’文件夹，再在其中新建cam0-16共17个文件夹
将sample_dataset/vid/000000/isp_out中的cam0-16，分别移动到output/rgb/cam0-16，并命名为000000.png
然后，
运行结果：

运行时间比较长，我的surround360没有安装加速部分，或许加了加速部分会好一点。
