OpenCV 4.x API 详解与C++实例-OpenCV开发环境搭建_opencv + sfm 配置 eigen3_dir

第二节 OpenCV开发环境搭建

1、硬件环境

CPU：Intel Core I7-9750H

GPU：Nvidia-Geforce RTX2060

OS：Windows 10 pro x64

硬盘：SSD 1TB

内存：32GB

2、开发工具

1）Visual Studio 2019 pro

2）Qt 5.15.2

3）CMake 3.19.1

4）Git for windows

5）Anoconda 3

6）JDK 8

7）Apache Ant

8）Visual Studio Code

下载并安装好上述工具

3、依赖库

1）TBB
2）Eigen
3）glog
4）gflags
5）Tesseract
6）leptonica
7）freetype2
8）harfbuzz
9）hdf5
10）Nvidia CUDA Toolkit 10.1
11）Nvidia CUDNN 7.6.1
12）VTK 8.2
13）OpenNI2

下载并编译好上述依赖库，或网上搜索已经编译好的库。

4、OpenCV源码下载

1）下载OpenCV源码：git clone https://github.com/opencv/opencv

2）下载OpenCV Contrib源码：git clone https://github.com/opencv/opencv_contrib

本文使用OpenCV版本为4.5.0。

5、OpenCV源码编译

定位到OpenCV源码目录，创建build文件夹，打开CMake gui，如下图

接下来逐个模块配置：

1）、关闭BUILD_PERF_TEST、BUILD_TEST选项

2）、开启WITH_TBB、WITH_CUDA、WITH_OPENGL、WITH_VTK 、OPENCV_ENABLE_NONFREE

3）、配置OPENCV_EXTRA_MODULES_PATH

再次点击CMake gui的configure按钮进行配置，然后配置各个依赖库：

1）glog库：GLOG_INCLUDE_DIRS、GLOG_LIBS、GLOG_LIBRARY

2）gflags库：gflags_DIR

3）TBB库：TBB_ENV_INCLUDE、TBB_ENV_LIB、TBB_VER_FILE

4）Tesseract库：Tesseract_INCLUDE_DIR、Tesseract_LIBRARY、Lept_LIBRARY

5）VTK库：VTK_DIR

6）Eigen库：EIGEN3_DIR

7）Java生成：ANT_EXECUTABLE

再次点击CMake gui的configure按钮，重新生成配置，最终结果如下：
