OpenCV概述和跨平台开发简介 OpenCV(Open Source Computer Vision Library)是一个开源计算机视觉库,提供了一系列图像处理和计算机视觉算法。它支持跨平台开发,允许开发者在不同的操作系统上构建和运行应用程序。 跨平台开发是一种开发策略,它允许应用程序在多个操作系统上运行,而无需针对每个操作系统进行专门开发。这可以节省开发时间和成本,并确保应用程序在不同平台上的行为一致。OpenCV通过提供跨平台API和库,支持跨平台开发。 # 2. OpenCV跨平台开发环境搭建 ### 2.1 Windows环境搭建 #### 2.1.1 安装Visual Studio - 下载并安装Visual Studio 2022或更高版本。 - 确保安装了适用于桌面开发的C++工作负载。 #### 2.1.2 安装OpenCV - 下载OpenCV最新版本,并选择适用于Windows的安装程序。 - 运行安装程序并按照提示进行操作。 - 确保将OpenCV添加到系统路径中。 #### 2.1.3 配置环境变量 - 打开控制面板,搜索“环境变量”。 - 在“系统变量”中添加以下变量: ``` 变量名:OPENCV_DIR 变量值:OpenCV安装目录 ``` - 在“用户变量”中添加以下变量: ``` 变量名:Path 变量值:%OPENCV_DIR%\bin;%Path% ``` ### 2.2 Linux环境搭建 #### 2.2.1 安装依赖项 - 更新包管理器: ``` sudo apt update ``` - 安装必要的依赖项: ``` sudo apt install build-essential cmake pkg-config libgtk2.0-dev libavcodec-dev libavformat-dev libswscale-dev ``` #### 2.2.2 安装OpenCV - 下载OpenCV最新版本,并选择适用于Linux的安装程序。 - 解压安装包,并进入解压目录: ``` tar -xzvf opencv-latest.tar.gz cd opencv-latest ``` - 编译并安装OpenCV: ``` mkdir build cd build cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. make sudo make install ``` #### 2.2.3 配置环境变量 - 打开终端,并添加以下变量: ``` export OPENCV_DIR=/usr/local/share/OpenCV export LD_LIBRARY_PATH=$OPENCV_DIR/lib:$LD_LIBRARY_PATH ``` ### 2.3 跨平台IDE选择和配置 #### 2.3.1 CLion - CLion是一款跨平台的C/C++ IDE,支持OpenCV开发。 - 安装CLion,并安装OpenCV插件。 - 创建一个新的OpenCV项目,并配置以下设置: ``` CMakeLists.txt: cmake_minimum_required(VERSION 3.18) project(opencv_project) find_package(OpenCV REQUIRED) target_link_libraries(opencv_project ${OpenCV_LIBRARIES}) ``` #### 2.3.2 Visual Studio Code - Visual Studio Code是一款免费且开源的代码编辑器,支持OpenCV开发。 - 安装Visual Studio Code,并安装C/C++扩展。 - 安装OpenCV扩展,并配置以下设置: ``` settings.json: { "C_Cpp.default.includePath": ["${env:OPENCV_DIR}/include"] } ``` #### 2.3.3 CMake - CMake是一个跨平台的构建系统,可用于配置和构建OpenCV项目。 - 创建一个CMakeLists.txt文件,并配置以下设置: ``` cmake_minimum_required(VERSION 3.18) project(opencv_project) find_package(OpenCV REQUIRED) target_link_libraries(opencv_project ${OpenCV_LIBRARIES}) ``` - 使用以下命令构建项目: ``` cmake . make ``` # 3.
