我正在使用g ++和opencv 2.4.6编写OpenCV项目

我有一些像这样的代码:

try 
{
    H = findHomography( obj, scene, CV_RANSAC );
}
catch (Exception &e)
{
    if (showOutput)
        cout<< "Error throwed when finding homography"<<endl;
    errorCount++;
    if (errorCount >=10)
    {
        errorCount = 0;
        selected_temp = -99;
        foundBB = false;
        bb_x1 = 0;
        bb_x2 = 0;
        bb_y1 = 0;
        bb_y2 = 0;
    }
    return -1;
}

当findHomography无法找到时,将抛出错误.错误消息包括:

OpenCV Error: Assertion failed (npoints >= 0 && points2.checkVector(2) 
== npoints && points1.type() == points2.type()) in findHomography,
