Openpose环境配置

配置环境一：

系统：Win10 professional
机器：HP-Z840-Workstation
处理器：Intel® Xeon® CPU E5-2660 v3 @ 2.60GHz × 40
显卡：Quadro K5200/PCIe/SSE2
opencv 4.0.0
cuda 10.1.0
cudnn7.5.0
VS 2017 professional
openpose :1.5.0

配置环境二：

操作系统 Windows 10 64位 professional
处理器 AMD Ryzen 5 2600X 六核
显卡 Nvidia GeForce GTX 1070 Ti ( 8 GB / 索泰 )
opencv 4.0.0
cuda 10.1.0
cudnn7.5.0
VS 2015 professional
openpose :1.5.0

经验一：安装NVIDIA驱动时，网上的教程大多是cuda8.0,实际安装时会有英文提示：may not have driver for this graphic(大致是这样)，如果忽略这个提示的话就会白干一场。所以选择最新的CUDA和CUDNN.

经验二：Cmake时选择x64

经验三：VS版本太低时会有414个关于"{“和”}"的报错，原因是因为C++的版本太低导致的格式错误。解决办法，使用更高的VS2017。不必局限于VS2015。

经验四：关于curtbase.dll的异常中断，原因是显卡性能太低导致的，比如显存太小。解决办法：更换更高配置的显卡，openpose要求可用显存大于2GB。

经验五：使用Release模式，不要使用debug

openpose调参：选择程序的运行功能，比如添加手部，脸部等骨骼功能时，进到#include 里

将false改为true，图片中已经改过了。
类似的脸部的可以找到

需要注意的是脸部耗源。
在这个文件里搜索write，可以找到保存结果的选项

可以看到有保存相片的，保存骨骼信息的（DEFINE_string(write_json, “”, 在双引号内填写保存路径就好了，使用双斜杠隔开，例如：DEFINE_string(write_json, “C:\\Users\\jack\\Desktop”）,不足之处是每张图片都会保存一个json文件，所以磁盘会变得很美丽。
