rv1126所使用的rknn sdk里默认是不带opencv库的，官方所用的例程里也没有使用opencv，但是这样在进行图像处理的时候有点麻烦了，这里有两种办法:

一是先用python将所需要的图片处理好后在转化为bin格式文件，在使用c++或c进行读取，可以参考->；

二是为其添加opencv库，可以直接在程序中调用opencv接口；下面介绍具体步骤

1：首先利用rv1126的交叉编译工具，将opencv源码生成可在rv1126上运行的库，参考

-> Rv1126移植opencv-CSDN博客

2:将编译生成的install下的所有文件拷贝支/3rdparty/opencv/下

3：编辑CMakeLists.txt
