Qt Creator简介和嵌入式系统开发概述 Qt Creator是一个跨平台的集成开发环境(IDE),专门用于开发基于C++的图形用户界面(GUI)应用程序。它提供了全面的工具和功能,包括代码编辑、调试、版本控制和项目管理。 嵌入式系统是设计用于执行特定任务的专用计算机系统。它们通常具有资源受限的特性,如有限的处理能力、内存和存储空间。嵌入式系统广泛应用于各种领域,包括汽车、医疗设备、工业自动化和物联网(IoT)。 Qt Creator是嵌入式系统开发的理想选择,因为它提供了针对嵌入式平台优化的工具和功能。它支持各种嵌入式操作系统和硬件平台,并提供了针对嵌入式开发的特定工具,如交叉编译器和调试器。 # 2. Qt Creator配置OpenCV环境 ### 2.1 OpenCV简介及安装 OpenCV(Open Source Computer Vision Library)是一个开源的计算机视觉库,提供广泛的图像处理和计算机视觉算法。它广泛应用于机器人、自动驾驶、医学成像和安防等领域。 **安装OpenCV** 在Qt Creator中使用OpenCV,需要先安装OpenCV库。可以通过以下步骤安装: 1. 下载OpenCV安装包:https://opencv.org/releases/ 2. 解压安装包到指定目录,例如:`/usr/local/opencv` 3. 配置环境变量: - 在终端中运行以下命令: ``` export OpenCV_DIR=/usr/local/opencv ``` - 将以下行添加到`.bashrc`或`.zshrc`文件中: ``` export PATH=$OpenCV_DIR/bin:$PATH ``` ### 2.2 Qt Creator与OpenCV集成 **创建Qt Creator项目** 1. 打开Qt Creator,创建一个新的Qt Widgets Application项目。 2. 在"项目"菜单中,选择"添加库"。 3. 在"添加库"对话框中,选择"外部库"选项卡。 4. 单击"添加"按钮,浏览并选择OpenCV库文件(例如:`/usr/local/opencv/lib/libopencv_core.so`)。 5. 重复步骤4,添加其他所需的OpenCV库,例如`libopencv_imgproc`、`libopencv_highgui`。 **配置项目文件** 1. 在Qt Creator中,打开项目文件(`.pro`文件)。 2. 在`HEADERS`部分,添加OpenCV头文件包含路径: ``` INCLUDEPATH += /usr/local/opencv/include ``` 3. 在`LIBS`部分,添加OpenCV库链接路径: ``` LIBS += -L/usr/local/opencv/lib -lopencv_core -lopencv_imgproc -lopencv_highgui ``` ### 2.3 项目配置和调试 **配置构建设置** 1. 在Qt Creator中,选择"项目"菜单,然后选择"构建设置"。 2. 在"构建设置"对话框中,选择"编译器"选项卡。 3. 在"其他编译器标志"字段中,添加以下标志: ``` -I/usr/local/opencv/include -L/usr/local/opencv/lib ``` **配置调试设置** 1. 在Qt Creator中,选择"运行"菜单,然后选择"配置运行环境"。 2. 在"运行环境"对话框中,选择"环境"选项卡。 3. 在"环境变量"部分,添加以下变量: ``` OpenCV_DIR=/usr/local/opencv ``` **运行项目** 1. 在Qt Creator中,单击"运行"按钮。 2. 如果项目配置正确,则将编译并运行项目。 3. 在项目中,可以使用OpenCV函数处理图像和进行计算机视觉操作。 # 3.1 嵌入式系统硬件选型 **硬件架构** 嵌入式系统的硬件架构通常分为以下几种类型: | 架构类型 | 特点 | 适用场景 | |---|---|---|
