Problem with push_back

edit

if (tecla==102) cap >> frame;

        if (tecla==32 and capturado==true)
        {
            //Aqui calculo los objectPoints
            for (int t=0; t<6; ++t)
            {
                for (int e=0; e<5; ++e)
                {
                    objectPoints.push_back(cv::Point3f(e*0.04,t*0.04,0));
                }
            }

            //Aqui calculamos cada objectPoints para cada imagen procesada.
            for (int n=0; n<total_img.size(); n++)
            {
                arrayObjectPoints[n].push_back( objectPoints );
            }


            capturado=false;
        }

    }

    cap.release();
    }

    }

This is my code. The problem is, where do push_back in line arrayObjectPoints[n].push_back( objectPoints ); The error is this.
