Question

我试图在Microsoft Visual Studio 2012中使用OpenCV 2.4.9进行相机校准，但我总是收到此错误：

Assertion failed (i < 0) in cv::_InputArray::getMat, file C:\buildslave64\win64_amdoc1\2_4_PackSlave-win32-vc11-shared\opencv\modules\core\src\matrix.cpp, line 963

这是我的校准部分代码：

m->srcLR.copyTo(webcamImage);
pyrUp(webcamImage, webcamImage);
cvtColor(webcamImage, gray, CV_BGR2GRAY);

bool found = findChessboardCorners(gray, cbSize, imagePoints, CALIB_CB_FAST_CHECK);

if (found)
{
    cout << "found";
    cornerSubPix(gray, imagePoints, Size(11, 11), Size(-1, -1), TermCriteria(CV_TERMCRIT_EPS+CV_TERMCRIT_ITER, 30, 0.1));
    drawChessboardCorners(webcamImage, Size(boardW, boardH), imagePoints, found);
}

if (waitKey(30) == char('c'))
{
    calibrateCamera(boardPoints, imagePoints, cbSize, intrinsics, distortion, rvecs, tvecs);
    cout << endl << intrinsics << endl;
    cout << endl << distortion << endl;
}

imshow("Calibrate Camera", webcamImage);
waitKey(10);

有关数据类型的详细信息：

boardPoints - ＆gt; Point3d的矢量

for (int i=0; i<boardW; i++) { for (int j=0; j<boardH; j++) { boardPoints.push_back(Point3d(double(i), double(j), 0.0)); } }

boardW = 9且boardH = 6。

imagePoints - ＆gt; Point2d的矢量
内在函数 - ＆gt; Mat，3x3
失真 - ＆gt; Mat，8x1
rvecs - ＆gt; Mat的矢量
tvecs - ＆gt; Mat的矢量

我对cornerSubPix和drawChessboardCorners进行了评论，因为我打算使用它，但它也会出错，我的主要目标是内在函数和失真矩阵。

其他信息：我在按下“c＆＃39;”时出现的错误。按钮。另一个错误发生在cornerSubPix和drawChessboardCorners中：

cornersubpix：

OpenCV Error: Assertion failed (ncorners >= 0 && corners.depth() == CV_32F) in cv::cornerSubPix, file C:\buildslave64\win64_amdocl\2_4_PackSlave-win32-vc11-shared\opencv\modules\imgproc\src\cornersubpix.cpp, line 257

drawchessboardcorners：

OpenCV Error: Assertion failed (nelems >= 0) in cv::drawChessboardCorners, file C:\buildslave64\win64_amdocl\2_4_PackSlave-win32-vc11-shared\opencv\modules\calib3d\src\calibinit.cpp, line 1939

断言在OpenCV的校准相机中失败
