OpenCV学习笔记-opencv介绍

OpenCV(Open source Computer Vision library)开源计算机视觉库。

基于BSD开源

图像处理，计算机视觉

跨平台：Windows，Linux，Moc OS，IOS，Android

编程接口：C, C++, Python, Java, Matlab

编程环境搭建

下载OpenCV3.4.0

https://www.opencv.org/releases.html

点击Win pack下载Windows版本，opencv-3.4.0-vc14_vc15.exe

解压到某个目录

安装VS2015社区版 (VS2015=vc14)

VS2015社区版官方中文版下载：

VS2015中配置OpenCV

新建一个win32控制台工程，空项目，属性管理器

Microsoft.Cpp.x64.user，双击，

包含目录：

库目录：

工程附加依赖项，Debug: opencv_world340d.lib; Release:opencv_world340.lib

工程输出目录修改：

新添QeC01.cpp

#include 

using namespace cv;

int main()
{
Mat imgSrc = imread("e:\\qetang\\Studyopencv\\images\\t.jpg");
imshow("imgsrc", imgSrc);

waitKey(5000);

return 0;
}

将opencv_world340d.dll拷贝到工程输出目录(….\bin\x64\Debug)下

将opencv_world340.dll拷贝到工程输出目录(….\bin\x64\Release)下

运行
