OpenCV图像处理基础** OpenCV(Open Source Computer Vision Library)是一个开源的计算机视觉库,广泛用于图像处理、视频分析和机器学习等领域。它提供了丰富的函数和算法,使开发者能够轻松实现各种图像处理任务。 在图像处理中,OpenCV支持图像读取、转换、增强、分割、特征提取和对象检测等功能。它还提供了机器学习算法,如支持向量机(SVM)和随机森林,用于图像分类和对象识别。 通过使用OpenCV,开发者可以快速构建强大的图像处理应用程序,用于各种应用场景,如面部识别、医疗成像和工业自动化。 # 2. 树莓派OpenCV颜色识别 ### 2.1 树莓派硬件简介 树莓派是一个微型单板计算机,以其低成本、高性能和广泛的用途而闻名。它配备了各种外围设备,包括: - **处理器:** Broadcom BCM2711B0,四核 ARM Cortex-A72 处理器,时钟频率 1.5GHz - **内存:** 4GB LPDDR4 内存 - **存储:** microSD 卡插槽,支持最大 256GB 存储 - **视频输出:** HDMI 端口,支持 4K 分辨率 - **音频输出:** 3.5mm 音频插孔 - **网络连接:** 千兆以太网端口和内置 Wi-Fi - **GPIO 引脚:** 40 个通用输入/输出引脚,用于连接传感器、执行器和其他设备 ### 2.2 OpenCV库安装和配置 OpenCV(Open Source Computer Vision Library)是一个开源计算机视觉库,提供广泛的图像处理和分析算法。在树莓派上安装 OpenCV 非常简单: 1. 更新软件包列表:`sudo apt-get update` 2. 安装 OpenCV:`sudo apt-get install python3-opencv` 3. 验证安装:`python3 -c 'import cv2; print(cv2.__version__)'` ### 2.3 颜色识别算法原理 树莓派上的颜色识别通常使用 HSV(色调、饱和度、亮度)颜色空间。HSV 模型将颜色表示为三个分量: - **色调 (H):** 颜色本身,从 0(红色)到 360(红色) - **饱和度 (S):** 颜色的强度,从 0(灰色)到 1(纯色) - **亮度 (V):** 颜色的亮度,从 0(黑色)到 1(白色) 颜色识别算法使用 HSV 模型将图像中的像素与预定义的颜色范围进行比较。当像素落在目标颜色范围内时,算法将其标记为该颜色。 ```python import cv2 # 定义目标颜色范围 lower_bound = np.array([0, 50, 50]) upper_bound = np.array([10, 255, 255]) # 转换图像到 HSV 颜色空间 hsv = cv2.cvtColor(image, cv2.COLOR_BGR2HSV) # 创建掩码以隔离目标颜色 mask = cv2.inRange(hsv, lower_bound, upper_bound) # 查找轮廓并绘制边界框 contours, _ = cv2.findContours(mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPL ```
