OpenCV 简介** OpenCV(Open Source Computer Vision Library)是一个开源计算机视觉库,为图像处理、视频分析和机器学习提供了广泛的算法和函数。它广泛应用于计算机视觉、图像分析、增强现实和机器人技术等领域。 OpenCV 提供了广泛的图像处理功能,包括图像读取、转换、增强、分割和目标检测。它还支持深度学习模型,用于图像分类、对象检测和图像分割等高级任务。OpenCV 具有跨平台兼容性,支持 Windows、Linux 和 macOS 操作系统。 # 2. VSCode 中 OpenCV 的集成 ### 2.1 安装和配置 OpenCV **安装 OpenCV** 在 VSCode 中安装 OpenCV,需要通过以下步骤: 1. 打开 VSCode,按 `Ctrl` + `Shift` + `X` 打开扩展市场。 2. 搜索 "OpenCV" 扩展,并安装。 3. 重启 VSCode。 **配置 OpenCV** 安装 OpenCV 扩展后,需要配置 OpenCV 的路径: 1. 打开 VSCode 设置(`Ctrl` + `,`),搜索 "OpenCV: OpenCV Path"。 2. 设置 OpenCV 的安装路径,例如:`C:\opencv\build\x64\vc15`。 3. 重启 VSCode。 ### 2.2 创建和运行 OpenCV 项目 **创建 OpenCV 项目** 1. 打开 VSCode,选择 "文件" -> "新建" -> "项目"。 2. 选择 "OpenCV 项目" 模板,并输入项目名称。 3. 点击 "创建"。 **运行 OpenCV 项目** 1. 在 VSCode 中打开 OpenCV 项目。 2. 按 `F5` 或单击 "运行" 按钮。 3. VSCode 将编译和运行 OpenCV 项目。 **代码示例** 以下是一个简单的 OpenCV 项目,用于读取和显示图像: ```cpp #include <opencv2/opencv.hpp> int main() { // 读取图像 cv::Mat image = cv::imread("image.jpg"); // 显示图像 cv::imshow("Image", image); cv::waitKey(0); return 0; } ``` **代码逻辑分析** * `cv::imread("image.jpg")`:读取名为 "image.jpg" 的图像并存储在 `image` 变量中。 * `cv::imshow("Image", image)`:创建一个名为 "Image" 的窗口并显示 `image` 图像。 * `cv::waitKey(0)`:等待用户按下任意键退出程序。 **参数说明** * `cv::imread()`: * 第一个参数:图像文件路径。 * 返回值:读取的图像,存储在 `cv::Mat` 变量中。 * `cv::imshow()`: * 第一个参数:窗口名称。 * 第二个参数:要显示的图像。 * `cv::waitKey()`: * 第一个参数:等待按下的键的毫秒数。0 表示等待任意键。 * 返回值:按下的键的 ASCII 码。 # 3.1 图像读取和显示 #### 图像读取 OpenCV 提供了多种函数来读取图像,最常用的函数是 `imread()`。该函数接受图像文件的路径作为参数,并返回一个 `Mat` 对象,其中包含图像数据。 ```python import cv2 # 读取图像 image = cv2.imread('image.jpg') ``` `imread()` 函数支持多种图像格式,包括 JPEG、PNG、BMP 和 TIFF。它还具有一个可选的 `flags` 参数,用于指定图像读取方式。例如,`cv2.IMREAD_COLOR` 标志读取彩色图像,而 `cv2.IMREAD_GRAYSCALE` 标志读取灰度图像。 #### 图像显示 读取图像后,可以使用 `imshow()` 函数显示图像。该函数接受图像的 `Mat` 对象和一个窗口名称作为参数。 ```python # 显示图像 cv2.imshow('Image', image) cv2.waitKey(0) cv2.destroyAllWindows() ``` `imshow()` 函数创建一个窗口并显示图像。它还等待用户按下任意键,然后关闭窗口。`waitKey()` 函数用于暂停程序执行,直到用户按下键。`destroyAllWindows()` 函数关闭所有 OpenCV 窗口。 ### 3.2 图像转换和增强 #### 图像转换 OpenCV 提供了多种函数来转换图像,包括调整大小、旋转和翻转。 **调整大小** `resize()` 函数用于调整图像的大小。它接受图像的 `Mat` 对象和新的尺寸作为参数。 ```python # 调整图像大小 image = cv2.resize(image, (300, 300)) ``` **旋转** `rotate()` 函数用于旋转图像。它接受图像的 `Mat` 对象、旋转角度和旋转中心作为参数。 ```python # 旋转图像 image = cv2.rotate(image, cv2.ROTATE_90_CLOCKWISE) ``` **翻转** `flip()` 函数用于翻转图像。它接受图像的 `Mat` 对象和翻转轴作为参数。 ```python # 翻转图像 image = cv2.flip(image, 0) ```
