OpenCV Aruco标记未在工业相机上识别

我正在检测工业自动化技术C2相机上的ARUCO标记，这些相机旨在检测三角测量扫描仪中的激光条纹，但它们也可以捕捉图像。我的问题是，无论我使用的相机如何，我都会检测到相同的标记，除了我之前提到的相机。我的代码最小工作例子如下：OpenCV Aruco标记未在工业相机上识别

#include <opencv2/highgui.hpp> 
#include <opencv2/aruco/charuco.hpp> 

using namespace std; 
using namespace cv; 

int main(int argc, char *argv[]) { 

int squaresX = 10; 
int squaresY = 7; 
float squareLength = 28; 
float markerLength = 19; 
int dictionaryId = 6; 
bool showRejected = true; 
bool refindStrategy = true; 

Ptr<aruco::DetectorParameters> detectorParams = aruco::DetectorParameters::create(); 

Ptr<aruco::Dictionary> dictionary = 
    aruco::getPredefinedDictionary(aruco::PREDEFINED_DICTIONARY_NAME(dictionaryId)); 

// create charuco board object 
Ptr<aruco::CharucoBoard> charucoboard = 
    aruco::CharucoBoard::create(squaresX, squaresY, squareLength, markerLength, dictionary); 
Ptr<aruco::Board> board = charucoboard.staticCast<aruco::Board>(); 

Mat image = imread("C:\\Users\\Piotrek\\Desktop\\calib\\022.jpg"), imageCopy; 

vector<int> markerIds, charucoIds; 
vector< vector<Point2f> > markerCorners, rejectedMarkers; 
vector<Point2f> charucoCorners; 

// detect markers 
aruco::detectMarkers(image, dictionary, markerCorners, markerIds, detectorParams, 
    rejectedMarkers); 

image.copyTo(imageCopy); 
if (markerIds.size() > 0) { 
    aruco::drawDetectedMarkers(imageCopy, markerCorners); 
} 

if (showRejected && rejectedMarkers.size() > 0) 
    aruco::drawDetectedMarkers(imageCopy, rejectedMarkers, noArray(), Scalar(100, 0, 255)); 

//display results 
imshow("out", imageCopy); 
waitKey(0); 

return 0; 
}

的问题是，检测到的标记，但不知什么原因，他们被拒绝：

Rejected markers

我用的OpenCV 3.1 。
