树莓派配置qt5和opencv4

换源(非常重要!!!)

树莓派的操作系统，基于 Debian 开发，所以要选择版本对应的源,如果你下载的树莓派官方提供的最新系统,就更新Debian 11(bullseye)源.

然后通过 uname -m 确定你使用的系统的架构

 uname -m

armv7l 用户：

sudo nano /etc/apt/sources.list
将原来的树莓派自带源注释,添加以下内容
deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ bullseye main non-free contrib rpi
deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ bullseye main non-free contrib rpi

下载安装 Qt5

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install qtbase5-dev qtchooser
sudo apt-get install qt5-qmake qtbase5-dev-tools
sudo apt-get install qtcreator
sudo apt-get install qtdeclarative5-dev

查看style是否等于gtk3

sudo nano /etc/xdg/qt5ct/qt5ct.conf

不是则改为gtk3.

扩大交换区,防止爆内存

sudo nano /sbin/dphys-swapfile
sudo nano /etc/dphys-swapfile

因为下载,编译opencv的步骤较多,所以这里为大家提供一个脚本,一键下载,编译opencv.

创建一个.sh脚本文件,并打开.

mkdir OpenCV-4-5-5.sh
sudo chmod 755 ./OpenCV-4-5-5.sh
sudo nano OpenCV-4-5-5.sh

将以下内容粘贴到OpenCV-4-5-5.sh中

#!/bin/bash
set -e
echo "Installing OpenCV 4.5.5 on your Raspberry Pi 32-bit OS"
echo "It will take minimal 2.0 hour !"
cd ~
# install the dependencies
sudo apt-get install -y build-essential cmake git unzip pkg-config
sudo apt-get install -y libjpeg-dev libtiff-dev libpng-dev
sudo apt-get install -y libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install -y libgtk2.0-dev libcanberra-gtk* libgtk-3-dev
sudo apt-get install -y libgstreamer1.0-dev gstreamer1.0-gtk3
sudo apt-get install -y libgstreamer-plugins-base1.0-dev gstreamer1.0-gl
sudo apt-get install -y libxvidcore-dev libx264-dev
sudo apt-get install -y python3-dev python3-numpy python3-pip
sudo apt-get install -y libtbb2 libtbb-dev libdc1394-22-dev
sudo apt-get install -y libv4l-dev v4l-utils
sudo apt-get install -y libopenblas-dev libatlas-base-dev libblas-dev
sudo apt-get install -y liblapack-dev gfortran libhdf5-dev
sudo apt-get install -y libprotobuf-dev libgoogle-glog-dev libgflags-dev
sudo apt-get install -y protobuf-compiler

# download the latest version
cd ~ 
sudo rm -rf opencv*
wget -O opencv.zip https://github.com/opencv/opencv/archive/4.5.5.zip 
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.5.5.zip 
# unpack
unzip opencv.zip 
unzip opencv_contrib.zip 
# some administration to make live easier later on
mv opencv-4.5.5 opencv
mv opencv_contrib-4.5.5 opencv_contrib
# clean up the zip files
rm opencv.zip
rm opencv_contrib.zip

# set install dir
cd ~/opencv
mkdir build
cd build

# run cmake
cmake -D CMAKE_BUILD_TYPE=RELEASE 
-D CMAKE_INSTALL_PREFIX=/usr/local 
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules 
-D ENABLE_NEON=ON 
-D WITH_OPENMP=ON 
-D WITH_OPENCL=OFF 
-D BUILD_TIFF=ON 
-D WITH_FFMPEG=ON

# run make
make -j4
sudo make install
sudo ldconfig

# cleaning (frees 300 MB)
make clean
sudo apt-get update

echo "Congratulations!"
echo "You've successfully installed OpenCV 4.5.5 on your Raspberry Pi 32-bit OS"

然后运行OpenCV-4-5-5.sh脚本文件

./OpenCV-4-5-5.sh

最后将交换空间重置回原来的 100 MB。闪存只能写入有限数量的周期。最后，它会磨损你的 SD 卡。

如果你有 4 GB 或 8 GB 内存的 Raspberry Pi 4，则不用做任何改变。只有当您拥有2 GB RAM 的 Raspberry Pi 4时，您才需要在 zram 配置文件中增加交换空间。增加交换空间的操作和上面的32位树莓派系统相同

(非必要)可以更新 EEPROM 的内容,在视觉应用中，只需更新 EEPROM 的内容，CPU 的热量就会从 65 °C (149 °F) 下降到 48 °C (118 °F),较低的 CPU 温度会延长树莓派的寿命。

sudo rpi-eeprom-update
sudo rpi-eeprom-update -a
sudo reboot

创建一个.sh脚本文件,并打开.

mkdir OpenCV-4-5-5.sh
sudo chmod 755 ./OpenCV-4-5-5.sh
sudo nano OpenCV-4-5-5.sh

将以下内容粘贴到OpenCV-4-5-5.sh中
