### getting part of the element of cv::findChessboardCorners

Hey,

I'm trying to get, the recognized points of the function cv::findChessboardCorners, let's say I got a 10*10 chessboard , I want to get the position of all localised points with this function even, if they're less than hat they should be (100) , any Idea how can I do this ?? here a small code of what I'm trying to do :

        std::vector<cv::Point2f> imagecrons;
cv::VideoCapture cap(0);
cv::Mat frame;
cap>> frame;
cv::Size board(10,10);
while(cv::waitKey(10)!=27){
cap >> frame;
cv::findChessboardCorners(frame, board, imagecrons);
std::cout << "image Points \n"  << imagecrons << std::endl; // I get either nothing or 100 ??
cv::imshow("",frame);
