全英文外贸网站建设,优惠活动制作网站,移动端模板,网页编辑快捷键默认没有带opencv库#xff0c;但是实际项目中需要用到opencv库#xff0c;因此添加一下此库#xff1b;
1#xff1a;编译opencv源码#xff0c;这里具体可以参考

1编译opencv源码这里具体可以参考
海思Hi3516移植opencv以及错误调试_海思hi3516摄像头开发-CSDN博客
2在工程的根目录下新建一个3rdparty文件用于存放第三方的库将编译安装好的库拷贝至3rdparty下并命名为opencv
3修改src下的CMakeLists.txt重点可以看一下#opencv的部分总的说就是查找opencv的库并链接到库即可
