我已经设置了ArUco库,现在想编写一个小代码来测试它是否正常工作。代码如下:
#include<opencv2/opencv.hpp>
#include<iostream>
#include<aruco.h>
#include<cvdrawingutils.h>
using namespace cv;
using namespace std;
using namespace aruco;
int main()
{
Mat image;
//Read image and display it
image = imread("E:/../Capture.PNG", 1);
if (image.empty()) //check whether the image is loaded or not
{
cout << "Error : Image cannot be loaded..!!" << endl;
//system("pause"); //wait for a key press
return -1;
}
namedWindow("Image", CV_WINDOW_AUTOSIZE);
imshow("Image", image);
waitKey(1000);
//Marker detection
MarkerDetector MDetector;
vector<Marker> Markers;
//I am not sure if we need to read the pattern of the marker. So I read it.
Markers = imread("E:/.../pattern.PNG", 1);
MDetector.detect(image, Markers);
//draw infor and its boundaries
for (int i = 0; i < Markers.size(); i++)
{
Markers[i].draw(image, Scalar(0, 0, 255), 2);
}
imshow("ouput", image);
waitKey(0);
}
这段代码构建时没有错误,但是当我运行它时,它会给我错误。
错误是:
这是我在休息时得到的结果
我使用Windows 8.1,Microsoft visual studio 2013,opencv 3.0和ArUco 1.3.0
任何帮助都会有所帮助。非常感谢您的帮助。
答案 0 :(得分:0)
这个问题已经解决了。我正在使用错误的标记模式。我们应该使用ArUco提供的标记模式。你可以在这里找到它们:http://terpconnect.umd.edu/~jwelsh12/enes100/markergen.html
代码中也有错误。正确的代码如下:
#include<opencv2/opencv.hpp>
#include<iostream>
#include<aruco.h>
#include<cvdrawingutils.h>
using namespace cv;
using namespace std;
using namespace aruco;
int main()
{
Mat image;
//Read image and display it
image = imread("E:/Studies/Master Thesis/Markers/arucoTest.PNG", 1);
if (image.empty()) //check whether the image is loaded or not
{
cout << "Error : Image cannot be loaded..!!" << endl;
//system("pause"); //wait for a key press
return -1;
}
namedWindow("Image", CV_WINDOW_AUTOSIZE);
imshow("Image", image);
waitKey(1000);
//Marker detection
MarkerDetector MDetector;
vector<Marker> Markers;
MDetector.detect(image, Markers);
//draw information and its boundaries
for (unsigned int i = 0; i<Markers.size(); i++) {
cout << Markers[i] << endl;
Markers[i].draw(image, Scalar(0, 0, 255), 2);
}
imshow("ouput", image);
waitKey(0);
}
我希望这个测试代码可以帮助新手ArUco(像我这样的其他人)。
