本文用QT调用OpenCV4.5.1进行相机标定。头文件如下#include <QMainWindow>#include <opencv2/opencv.hpp>#include <iostream>#include <math.h>#include <fstream>#include <vector>using namespace cv;using namespace std;1.进行摄像机的读取，用O.

Mat类分为了两个部分:1.矩阵头和指向矩阵数据部分的指针，2.data就是指向矩阵数据的指针。下面是VS调试显示属性：flags：flags是int类型，共占32位，从低位到高位：0-2位代表depth即数据类型（如CV_8U），OpenCV的数据类型共7类，故只需3位即可全部表示。3-11位代表通道数channels，因为OpenCV默认最大通道数为512，故只需要9位即可全部表示，可参照下面求通道数的部分。0-11位共同代表type即通道数和数据类型（如C.

人脸检测是计算机视觉最典型的应用之一，早期OpenCV的logo就是Haar人脸检测的示意图。很多人的第一个OpenCV学习目标就是跑通Haar级联人脸检测，Dlib库在业内开始流行很大程度上是因为其HOG-SVM人脸检测比OpenCV Haar的好，而近年来OpenCV和Dlib均已包含基于深度学习的人脸检测算法实现。Haar-Cascade,HOG-SVM,深度学习正是代表着人脸检测乃...
