Error When Copying a Vector into another vector - c++

Question

There are two vectors "ImgCoordinatesList" & "ImgCoordinatesListCopy".
The first vector continuously receives values which are pushbacked.(x,y,Type - I have previously defined a struct which has int,int,string and its object is list_obj)
Once the function "ImgCreation" is called, the contents of the first vector should be copied into the "ImgCoordinatesListCopy" vector and the contents inside this copy vector should be used for further processing.
But the method what i did produced errors.
void SliceImageNew::BuildImgCoordinatesList(const long X, const long Y, string Type)
{
//Creates the Structure for one x,y,type coordinate
list_obj.x = X;
list_obj.y = Y;
list_obj.Coordinates_Type = Type;
//Pushes the structure into a vector which eventually forms a vector of structs
ImgCoordinatesList.push_back(list_obj);
}
void SliceImageNew::ImgCreation()
{
ImgCoordinatesListCopy.resize(ImgCoordinatesList.size());
copy(ImgCoordinatesList.begin(), ImgCoordinatesList.end(), ImgCoordinatesListCopy.begin());
//ImgCoordinatesListCopy = ImgCoordinatesList; //Copy the contents into another vector and create image with the copy vector
ImgCoordinatesList.erase(ImgCoordinatesList.begin(), ImgCoordinatesList.end());//Clear the vector after copying the contents into another vector
PlotImgCoordinates();
//SaveSliceImg();
//ClearImgCoordinatesList();
}
void SliceImageNew::PlotImgCoordinates()
{
static int SliceImgCount = 1;
Mat SliceImg(Size(1920, 1080), CV_16UC3); // Blank Image with White Background and 1920*1080 Dimensions
for (int i = 1; i!=ImgCoordinatesListCopy.size(); i++)
{
//Color differentiation between Mark and Jump Lines
if (ImgCoordinatesListCopy[i].Coordinates_Type == "Mark")
{
//cout << "This is a mark line" << endl;
line(SliceImg, Point(ImgCoordinatesListCopy[i - 1].x, ImgCoordinatesListCopy[i - 1].y), Point(ImgCoordinatesListCopy[i].x, ImgCoordinatesListCopy[i].y), Scalar(255, 255, 155), 4, 2, 0);
}
else
{
//cout << "This is a jump line" << endl;
line(SliceImg, Point(ImgCoordinatesListCopy[i - 1].x, ImgCoordinatesListCopy[i - 1].y), Point(ImgCoordinatesListCopy[i].x, ImgCoordinatesListCopy[i].y), Scalar(255, 100, 155), 4, 2, 0);
}
}
//Creating Legends for the Plot
putText(SliceImg, "Mark Line", cvPoint(1600, 40),
FONT_HERSHEY_SIMPLEX, 0.8, (255, 0, 0), 2);
line(SliceImg, Point(1540, 35), Point(1590, 35), Scalar(255, 255, 155), 4, 2, 0);
putText(SliceImg, "Jump Line", cvPoint(1600, 80),
FONT_HERSHEY_SIMPLEX, 0.8, (255, 0, 0), 2);
line(SliceImg, Point(1540, 75), Point(1590, 75), Scalar(255, 100, 155), 4, 2, 0);
//Providing unique names for every picture that is being saved
name << "Slice" << SliceImgCount << ".jpg";
// Saving the image
imwrite(name.str(), SliceImg);
SliceImgCount++; //Increment the count to provide unique names to the images
waitKey(0);
}
I have attached an image which shows the code and the error generated
While debugging, the highlighted line in the image produced that error!
Could someone help me?

Found the solution!
I had messed up with the object declaration of the "SliceImageNew" class. After correction it works fine and draws the image perfectly.
