我在Visual Studio 2015中使用OpenCV-3.1.0编写程序。大多数操作都正常,但是,我收到了访问冲突错误。我已经调试了项目,在执行faceClassifier.load(" haarcascade_frontalface_alt.xml")后,Locals窗口显示"信息不可用,没有为opencv_world310.dll加载符号"。这是代码:
#include "opencv2/objdetect.hpp"
#include "opencv2/videoio.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/imgproc.hpp"
#include <iostream>
#include <stdio.h>
using namespace std;
using namespace cv;
void detectAndDisplay(Mat);
int main()
{
Mat img = imread("faces.jpg");
detectAndDisplay(img);
return 0;
}
void detectAndDisplay(Mat img)
{
CascadeClassifier faceClassifier;
faceClassifier.load("haarcascade_frontalface_alt.xml");
vector<Rect> faces;
Mat gray;
cvtColor(img, gray, CV_BGR2GRAY);
faceClassifier.detectMultiScale(gray, faces,1.1,3,0);
for (int i = 0; i < faces.size(); i++)
{
Point center(faces[i].x + faces[i].width*0.5, faces[i].y + faces[i].height*0.5);
ellipse(img, center, Size(faces[i].width*0.5, faces[i].height*0.5), 0, 0, 360, Scalar(255, 0, 255), 4, 8, 0);
}
namedWindow("Faces", 1);
while (true)
{
imshow("Faces", img);
if (waitKey(30) >= 0) break;
}
}
答案 0 :(得分:0)
您没有使用OpenCV调试库。普通库不包含调试信息。
调试库在.dll
或.lib
尝试
opencv_world310d.dll
