opencv_and_opencv_contrib

介绍

Android NDK-r21 编译 opencv-3.3.1 + opencv_contrib-3.3.1

安装教程

1. sudo apt-get install cmake

2. 官网下载NDK: android-ndk-r21，SDK可以不需要.

3. 下载opencv和opencv_contrib，切换到3.3.1版本. git clone https://github.com/opencv/opencv.git git clone https://github.com/opencv/opencv_contrib.git 推荐更快的国内地址： https://www.bzblog.online/wordpress/index.php/2020/03/09/opencvdownload/

4. 下载path包： 如果你要问我为什么，我只能告诉你，这个是我踩过的坑(https://github.com/opencv/opencv_contrib/issues/1301). https://github-production-repository-file-5c1aeb.s3.amazonaws.com/12756992/4520852?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAIWNJYAX4CSVEH53A%2F20201212%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20201212T150158Z&X-Amz-Expires=300&X-Amz-Signature=63b69d60980b1e7f6828c312b27a2601fc49e758ddad57907753fc072d266a7e&X-Amz-SignedHeaders=host&actor_id=0&key_id=0&repo_id=12756992&response-content-disposition=attachment%3Bfilename%3Dpatch__.zip&response-content-type=application%2Fzip 解压到目录： /home/gmy/disk0/mingyi/gitee/opencv/opencv-3.3.1/.cache/xfeatures2d/

5. 进入opencv源码目录，配置好相关变量路径，然后执行下面的脚本. ########################################################################### #!/bin/sh

cd $opencv_dir rm -rf build && mkdir build cp build.sh build/ cd build/

make -j12 && make install
