OpenCV简介 ### 2.1 OpenCV概述 OpenCV(Open Source Computer Vision Library)是一个开源的计算机视觉库,它提供了丰富的图像处理和计算机视觉算法。OpenCV广泛应用于图像处理、计算机视觉、机器学习和人工智能等领域。 OpenCV具有以下特点: - **开源和免费:**OpenCV是开源的,可以免费使用和修改。 - **跨平台:**OpenCV支持Windows、Linux和macOS等多个平台。 - **丰富的功能:**OpenCV提供了图像处理、计算机视觉、机器学习和人工智能等方面的丰富功能。 - **活跃的社区:**OpenCV拥有一个活跃的社区,提供支持和资源。 ### 2.2 OpenCV的安装和配置 #### 2.2.1 Windows安装 **步骤 1:下载 OpenCV 安装包** 从 OpenCV 官方网站下载适用于 Windows 的 OpenCV 安装包。 **步骤 2:安装 OpenCV** 运行安装包并按照提示进行安装。确保选择 "Add OpenCV to the system PATH" 选项。 #### 2.2.2 Linux安装 **步骤 1:安装依赖项** ``` sudo apt-get update sudo apt-get install build-essential cmake git pkg-config ``` **步骤 2:克隆 OpenCV 源代码库** ``` git clone https://github.com/opencv/opencv.git ``` **步骤 3:编译和安装 OpenCV** ``` cd opencv mkdir build cd build cmake -D CMAKE_BUILD_TYPE=Release .. make -j4 sudo make install ``` #### 2.2.3 验证安装 在命令行中输入以下命令验证安装: ``` opencv_version ``` 如果显示 OpenCV 版本信息,则表示安装成功。 #### 代码示例: ```cpp #include <opencv2/opencv.hpp> using namespace cv; int main() { // 创建一个图像 Mat image = imread("image.jpg"); // 显示图像 imshow("Image", image); // 等待用户输入 waitKey(0); // 释放图像资源 destroyAllWindows(); return 0; } ``` **逻辑分析:** 该代码示例演示了如何使用 OpenCV 读取和显示图像。 - `imread("image.jpg")`:读取名为 "image.jpg" 的图像并将其存储在 `image` 变量中。 - `imshow("Image", image)`:创建一个名为 "Image" 的窗口并显示 `image` 图像。 - `waitKey(0)`:等待用户输入,按任意键退出程序。 - `destroyAllWindows()`:释放所有 OpenCV 窗口。 **参数说明:** - `imread`
