I need to calculate the positon of a person in a room and display it on a map of the building.
So I have a few problems to deal with.
How do I calculate the position of the person?
I know one point of a rectangle that is around the face and its size (Pixel). I also know the size (Pixel) of the picture and the position of the camera (Height, where it is in the room).
With that, I need to calculate the position of the person in the picture to a ground plan of the room/building.
Is it possible to calculate it or need I/you more information about it?
And how do I get the position of the person on the map of the building?
I´m thankful for any kind of help.
