OpenCV图像处理基础 **1.1 OpenCV概述** OpenCV(Open Source Computer Vision Library)是一个开源的计算机视觉库,提供一系列图像处理和计算机视觉算法。它广泛应用于各种领域,包括机器人、自动驾驶、医疗成像和安全。 **1.2 OpenCV图像处理流程** 图像处理是一个涉及图像获取、增强、分析和理解的复杂过程。OpenCV提供了从图像获取到图像分析的完整流程。其典型流程包括: * **图像获取:**从摄像头、文件或其他来源获取图像。 * **图像预处理:**对图像进行预处理,如调整大小、转换格式和去除噪声。 * **图像分析:**使用算法和技术分析图像,提取特征和信息。 * **图像理解:**基于分析结果理解图像的内容和意义。 # 2. OpenCV图像处理实践 ### 2.1 图像读取、显示和保存 #### 2.1.1 图像的读取和显示 **代码块 1:图像读取和显示** ```python import cv2 # 读取图像 image = cv2.imread("image.jpg") # 显示图像 cv2.imshow("Image", image) cv2.waitKey(0) cv2.destroyAllWindows() ``` **逻辑分析:** * `cv2.imread()` 函数用于读取图像文件,返回一个 NumPy 数组。 * `cv2.imshow()` 函数用于显示图像。 * `cv2.waitKey(0)` 函数等待用户按下任意键关闭窗口。 * `cv2.destroyAllWindows()` 函数销毁所有打开的窗口。 **参数说明:** * `image`: 要读取的图像文件路径。 * `window_name`: 显示图像的窗口名称。 * `delay`: 等待用户按下键的时间(以毫秒为单位)。 #### 2.1.2 图像的保存和格式转换 **代码块 2:图像保存和格式转换** ```python # 保存图像 cv2.imwrite("image_saved.jpg", image) # 转换图像格式 image_gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) cv2.imwrite("image_gray.jpg", image_gray) ``` **逻辑分析:** * `cv2.imwrite()` 函数用于保存图像文件。 * `cv2.cvtColor()` 函数用于转换图像格式。 * 在本例中,将图像从 BGR(蓝色、绿色、红色)格式转换为灰度格式。 **参数说明:** * `filename`: 要保存的图像文件路径。 * `image`: 要保存的图像数组。 * `code`: 要保存的图像格式代码(例如,`cv2.IMWRITE_JPEG`)。 ### 2.2 图像处理基本操作 #### 2.2.1 图像的灰度化和二值化 **代码块 3:图像灰度化和二值化** ```python # 灰度化 image_gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # 二值化 threshold = 127 image_binary = cv2.threshold(image_gray, thresho ```
