代码说明:

基于opencv摄像机标定,利用电脑摄像头进行棋盘标定检测 对相机标定的说明:利用OpenCV对相机进行标定的过程,可参看OpenCV提供的帮助文档,非常的有用。我在这里说明一些关键的,希望对大家有所帮助。一、本程序由于格子的实际坐标是随意给的(当然也有一定方法),所以也就是说“世界坐标系是动的,每幅图像一个”,故每幅图像有一个外参数阵;二、从一般标定之后的工作来说,在这步标定中所计算得到的外参数基本没用,所以我们不关心外参数;三、我们主要关心的是内参数,只要相机的焦距不变,内参数就不变。另外,要说明一下,代码大量参照了OpenCV中文官方网上给出的相机标定的代码,但是那个代码有些问题,而且还让人不知怎么运行!这些我这里已经做了修改;标定的所需的棋盘图片,大家可自己照,也是去http://graphics.cs.msu.su/en/research/calibration/上去找,上面提供了三组标定用的图片。                               

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    Object detection (or rather, recognition) is one of the fundamental problems in computer vision and a lot of techniques have come up to solve it. This is a Project about Real-time object detection in OpenCV using SURF.

  • opencv显示图像
    利用VS2012配置opencv2410.MFC并通过opencv图像库文件,实现一张二维图像显示。2017年07月07日。penCV用C++语言编写,它的主要接口也是C++语言,但是依然保留了大量的C语言接口。该库也有大量的Python, Java and MATLAB/OCTAVE (版本2.5)的接口。这些语言的API接口函数可以通过在线文档获得。如今也提供对于C#,Ch, Ruby的支持。

    目标跟踪算法,基于kalman滤波的meanshift目标跟踪算法(With the rapid development of hardware and software technology and machine intelligence at home and abroad, more and more attention has been paid to the research subject of computer vision. People have begun to have a rich interest in visual information. Vision is an important part of various applications, such as medical diagnosis, military analysis, and aerospace intelligent systems. At the same time, a large number of researchers have done a variety of research on computer vision, including video based targets.)
