vector initialize error?

[bbbrian94]

in the line of 82 and 155 of your vpdetection.cpp you i got error below:

error: no matching function for call to ‘std::vector<std::vector<cv::Point3_ > >::_M_fill_initialize and so on.

[bbbrian94]

plz merge this one to the issue 1 i am sorry

//vpHypo = std::vector<std::vector<cv::Point3d>> ( it * numVp2, 3 );
vpHypo = std::vector<std::vector<cv::Point3d> > ( it * numVp2, std::vector<cv::Point3d>(3) );

Change like this.
