2023-04-20记录一下，来自我的博文RK3588在Ubuntu20.04上源码编译OpenCV3.4.16的C++、Python版本
Python版本可以了，调用摄像头也ok，C++的调用摄像头还存在一些问题。
1、卸载之前安装的OpenCV
就是之前记录的：RK3588卸载OpenCV3.4.16
2、安装Eigen3
就是之前记录的文章：RK3588安装Eigen3
3、安装OpenCV3.4.16
- 参考资料：
1、RK3588安装OpenCV3.4.16【第一次记录的，不过似乎没有装好，这次再来】
2、ubuntu系统编译安装OpenCV 4.4并配置C++和Python开发环境
3、【CV实战】Ubuntu18.04源码编译安装opencv-3.4.X+测试demo
4、Install OpenCV-Python in Ubuntu
5、Installation in Linux
3.1、对应的工具要求
在官网Installation in Linux上可以看到对工具的要求：
- Required Packages ：
- 1、 GCC 4.4.x or later
- 2、CMake 2.8.7 or higher
- 3、Git
- 4、GTK+2.x or higher, including headers (libgtk2.0-dev)
- 5、 pkg-config
- 6、Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy)
- 7、ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev
- 8、 [optional] libtbb2 libtbb-dev
- 9、 [optional] libdc1394 2.x
- 10、[optional] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev
- 11、[optional] CUDA Toolkit6.5 or higher
需要Python2.6版本以上，这里采用了3.8。
python3.8不是系统默认的Python版本，需要进行替换。
3.1.1、配置系统默认的python版本
- 参考：
1、【Python】Ubuntu修改默认Python版本
2、ubuntu 16.04下切换python版本小结
3.1.1.1、系统级的配置
- 1、从上面的信息可以看到，没有
python的软连接，如果是有，在需要删除：sudo rm /usr/bin/python。这里没有这个，就不用删除了，直接跳过。
- 2、创建一个
python的软连接到指定的Python版本：
sudo ln -s /usr/bin/python3.8 /usr/bin/python
这样就行了，因为没有其他的python版本造成干扰。
- 3、pip错误
解决方法是将pip版本更改为符合当前的Python版本。对于Python2或者Python3：
sudo apt-get update
sudo apt-get install python-pip #python2
sudo apt-get install python3-pip #python3
3.2、安装对应的依赖
本次的目标是要编译成C++、Python版本，两者都是需要的，因此依赖需要安装C++的依赖、Python的依赖。
执行命令：
sudo apt-get update
3.2.1、安装编译依赖
- 1、根据参考资料，安装编译所需的依赖【C++版本所需】：
sudo apt-get install build-essential
- 2、安装cmake 【都需要】、git、pkg-config、gcc、g++ ：
# 都需要
sudo apt-get install cmake git pkg-config
# 一般都自带有，不需要安装，没有的话就需要装上：
sudo apt-get install gcc g++
- 3、GTK支持(图形界面库)
# 安装gtk2支持
sudo apt-get install libgtk2.0-dev
# 安装gtk3支持
sudo apt-get install libgtk-3-dev
- 4、安装摄像头库支持（v4l）、流媒体支持（fmpeg, gstreamer）
这个很重要，不然可能没法打开摄像头，这次重装就是因为没法打开摄像头调用数据，我感觉就是因为上次没有安装这个！！！！

- 5、安装libtbb2、libtbb-dev【可选】
sudo apt-get install libtbb2 libtbb-dev
- 6、安装python2、python3支持模块【可选】
可选，譬如你可以只打算在python3里用opencv，那么就忽略python2的模块安装。
# 安装python2支持
sudo apt-get install python-dev python-numpy
# 安装python3支持
sudo apt-get install python3-dev python3-numpy
- 7、可选图片支持库【可选】
用于处理多种图片格式（可选）
sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev libopenexr-dev libwebp-dev
#后面两种 libopenexr-dev libwebp-dev 加进来的，opencv官方给的安装指导没有
如果有的话，就不用安装了。
# 总的安装
sudo apt-get install build-essential cmake git pkg-config gcc g++ libgtk2.0-dev libgtk-3-dev libavcodec-dev libavformat-dev libswscale-dev libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev libtbb2 libtbb-dev python3-dev python3-numpy libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev libopenexr-dev libwebp-d

看到，有两个库没有安装成功：libjasper-dev、libwebp-dev
tips：
在ubuntu系统编译安装OpenCV 4.4并配置C++和Python开发环境给出了好多依赖，不太认识，以后有机会好好研究一下。
- 可能的报错：
topeet@iTOP-RK3588:~ $ sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev libopenexr-dev libwebp-d
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libjasper-dev
E: Unable to locate package libwebp-d
参考：
1、用 add-apt-repository 管理 apt-get 源
2、OpenCV安装libjasper-dev依赖包错误：E: Unable to locate package libjasper-dev
- 解决【没解决】：
# 因为系统是Ubuntu20.04的，把 xenial-security 改为 focal-security
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu focal-security main"
sudo apt install libjasper-dev libwebp-d
# 删除刚刚加入的源
sudo add-apt-repository --remove "deb http://security.ubuntu.com/ubuntu focal-security main"
sudo apt-get update
# 修复可能安装出错的依赖, -f 参数的意思是 fix broken（修复依赖包）
sudo apt-get install -f
解决不了，算了，也不是什么很重要的库。
3.3、开始安装OpenCV
- 1、在OpenCV文件下创建
build文件夹：
sudo mkdir build && cd build
- 2、配置编译信息
参考：
1、ubuntu系统编译安装OpenCV 4.4并配置C++和Python开发环境
2、Installation in Linux
3、OpenCV 配置选项参考文档
sudo cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D OPENCV_ENABLE_NONFREE=ON \
-D OPENCV_EXTRA_MODULES_PATH=/home/topeet/Downloads/opencv-3.4.16/opencv_contrib-3.4.16/modules \
-D OPENCV_GENERATE_PKGCONFIG=YES \
-D WITH_QT=ON \
-D WITH_OPENGL=ON \
-D WITH_CUDA=OFF\
-D BUILD_EXAMPLES=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=ON \
-D PYTHON3_EXECUTABLE=/usr/bin/python \
-D PYTHON_INCLUDE_DIR=/usr/include/python3.8 \
-D PYTHON_INCLUDE_DIR2=/usr/include/aarch64-linux-gnu/python3.8 \
-D PYTHON_LIBRARY=/usr/lib/aarch64-linux-gnu/libpython3.8.so \
-D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3.8/dist-packages/numpy/core ..
参数解释：
CMAKE_BUILD_TYPE安装的版本，Release\Debug，选择发行版Release,默认安装ReleaseCMAKE_INSTALL_PREFIX是最终OpenCV的安装位置，默认安装在usr/localOPENCV_ENABLE_NONFREE是否使用部分被申请了专利的算方法 这里选True的话就可以使用了OPENCV_EXTRA_MODULES_PATH指示扩展算法的源码文件夹OPENCV_GENERATE_PKGCONFIG强烈建议开启这个 设置为ON。因为opencv4默认不生成.pc文件，所以加上这句用于生成opencv4.pc文件，支持pkg-config功能。opencv4版本及以上 这里用ONPYTHON3_NUMPY_INCLUDE_DIRS跟官方给的不太一样，没有include文件夹WITH_CUDA该选项需要确保自己已安装显卡驱动和cuda
没有空格的版本：
sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_ENABLE_NONFREE=ON -D OPENCV_EXTRA_MODULES_PATH=/home/topeet/Downloads/opencv-3.4.16/opencv_contrib-3.4.16/modules -D OPENCV_GENERATE_PKGCONFIG=YES -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_CUDA=OFF -D BUILD_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=ON -D PYTHON3_EXECUTABLE=/usr/bin/python -D PYTHON_INCLUDE_DIR=/usr/include/python3.8 -D PYTHON_INCLUDE_DIR2=/usr/include/aarch64-linux-gnu/python3.8 -D PYTHON_LIBRARY=/usr/lib/aarch64-linux-gnu/libpython3.8.so -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3.8/dist-packages/numpy/core ..

3.4、配置OpenCV
暂无，直接就用了
3.5、测试OpenCV
在RK3588上测试
3.5.1、查看版本
topeet@iTOP-RK3588:~/Downloads/opencv-3.4.16/build $ pkg-config opencv --modversion
3.4.16
3.5.2、Python版本测试
topeet@iTOP-RK3588:~/Downloads/opencv-3.4.16/build $ python
Python 3.8.10 (default, Mar 13 2023, 10:26:41)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'3.4.16'
>>>
3.5.3、C++demo测试
在源码包路径中找到官方给的demo：/home/topeet/Downloads/opencv-3.4.16/samples/cpp/example_cmake/，直接编译运行：
sudo mkdir build && cd build
sudo cmake ..
sudo make
sudo ./opencv_example
能够编译，但是不能很好运行：
topeet@iTOP-RK3588:~/Downloads/opencv-3.4.16/samples/cpp/example_cmake/build $ sudo ./opencv_example
Built with OpenCV 3.4.16

在本地串口中运行结果如下：
起码能够打开摄像头了，虽然还存在一定问题，到时候再看看！！
3.5.3、Python demo测试
测试程序
结果：
可以正常显示
3.5.4、Python调用摄像头测试
import cv2
import time
def main():
# 使用GStreamer管道从MIPI摄像头捕获视频，添加视频帧率
gst_pipeline = 'v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=640,height=480,framerate=30/1 ! appsink'
# 从GStreamer管道创建OpenCV VideoCapture对象
cap = cv2.VideoCapture(gst_pipeline, cv2.CAP_GSTREAMER)
if not cap.isOpened():
# 如果无法打开摄像头，则输出提示信息
print("无法打开摄像头")
return
time0 = time.time() # 获取开始时间
while True:
# 从摄像头捕获帧
ret, frame = cap.read()
frame = cv2.cvtColor(frame, cv2.COLOR_YUV2BGR_NV12)
# 如果捕获到帧，则显示它
if ret:
time1 = time.time() # 获取结束时间
fps = 1 / (time1 - time0) # 计算实时帧率
time0 = time1 # 更新开始时间
cv2.putText(frame, "FPS: {:.2f}".format(fps), (10, 30), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2) # 在图像上显示帧率
cv2.imshow("MIPI Camera", frame)
# 按下'q'键退出循环
if cv2.waitKey(1) & 0xFF == ord("q"):
break
# 释放资源并关闭窗口
cap.release()
cv2.destroyAllWindows()
if __name__ == "__main__":
main()
结果：
topeet@iTOP-RK3588:~/Documents $ python testOV6595.py
Using mplane plugin for capture
