[OpenWrt]安装opencv

发表于 分类于

Makefile修改

修改 /openwrt-hiwooya/feeds/packages/libs/opencv/Makefile，把版本改为3.0.0（没有opencv文件夹则新建）

下载速度慢的话，先把 opencv-3.0.0.zip（点击下载） 包放入 /openwrt-hiwooya/dl 文件夹中

define Package/opencv/Default/description
 OpenCV (Open Source Computer Vision Library) is an open source computer
 vision and machine learning software library. OpenCV was built to provide
 a common infrastructure for computer vision applications and to accelerate
 the use of machine perception in the commercial products. Being a
 BSD-licensed product, OpenCV makes it easy for businesses to utilize
 and modify the code.
