How can I convert known GPS coordinates to image pixels, and again image pixels to world GPS coordinates?

I have few known points in an image and same points I have as GPS coordinates also. How can I georeference my image to get all points in the image as GPS points?

Is this a triangulation problem?

I want to get some desired unknown points in the image as GPS coordinates.

A simple start would be to get any two points:

dx = abs(point2gpsx - point1gpsx)/abs(point2imagex - point1imagex)

So by using a simple ratio, find how long a single pixel is in the x direction in GPS coordinates. Repeat for y direction. Then you can calculate the edges of the image in GPS coordinates, then use a meshgrid to get the coordinates for the rest.
