OpenCV图像处理基础 ### 2.1 图像的获取和显示 #### 2.1.1 图像的读写操作 **读取图像** ```python import cv2 # 读取图像 image = cv2.imread("image.jpg") ``` **参数说明:** * `image.jpg`: 图像文件路径 **逻辑分析:** `cv2.imread()` 函数读取指定路径的图像文件并返回一个 NumPy 数组,该数组包含图像的像素值。 **写入图像** ```python cv2.imwrite("new_image.jpg", image) ``` **参数说明:** * `new_image.jpg`: 保存图像的路径 * `image`: 要保存的图像数组 **逻辑分析:** `cv2.imwrite()` 函数将图像数组保存为指定路径的图像文件。 #### 2.1.2 图像的显示和转换 **显示图像** ```python cv2.imshow("Image", image) cv2.waitKey(0) ``` **参数说明:** * `Image`: 图像窗口的标题 * `image`: 要显示的图像数组 * `0`: 等待用户按任意键关闭窗口 **逻辑分析:** `cv2.imshow()` 函数创建一个图像窗口并显示图像数组。`cv2.waitKey(0)` 函数等待用户按任意键关闭窗口。 **图像转换** ```python gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) ``` **参数说明:** * `image`: 输入图像数组 * `cv2.COLOR_BGR2GRAY`: 颜色空间转换代码,将 BGR 颜色空间转换为灰度空间 **逻辑分析:** `cv2.cvtColor()` 函数将图像从一种颜色空间转换为另一种颜色空间。 ### 2.2 图像的基本操作 #### 2.2.1 图像的裁剪和缩放 **裁剪图像** ```python cropped_image = image[y:y+h, x:x+w] ``` **参数说明:** * `image`: 输入图像数组 * `y`: 裁剪区域的起始 y 坐标 * `h`: 裁剪区域的高度 * `x`: 裁剪区域的起始 x 坐标 * `w`: 裁剪区域的宽度 **逻辑分析:** `image[y:y+h, x:x+w]` 语法用于从图像数组中裁剪指定区域。 **缩放图像** ```python scaled_image = cv2.resize(image, (width, height)) ``` **参数说明:** * `image`: 输入图像数组 * `width`: 缩放后的图像宽度 * `height`: 缩放后的图像高度 **逻辑分析:** `cv2.resize()` 函数将图像缩放为指定的大小。 #### 2.2.2 图像的旋转和翻转 **旋转图像** ```python rotated_image = cv2.rotate(image, cv2.ROTATE_90_CLOCKWISE) ``` **参数说明:** * `image`: 输入图像数组 * `cv2.ROTATE_90_CLOCKWISE`: 顺时针旋转 90 度 **逻辑分析:** `cv2.rotate()` 函数将图像旋转指定角度。 **翻转图像** ``` ```
