Pixel (x/y) to latitude & longitude conversion on a given image

I need a PHP function that returns latitude & longitude for a given point (x/y) within a picture.

Unfortunately the image is not a flat image and taken from a specific angle/height. (see attached file)

Two possible soloutions:

1) calculate any long/lat based on all needed camera paramteres (lat/long from the point of view, [url removed, login to view],vertical angle,height etc.)

2) estimate any long/lat based on already defined points within the image. The estimation should be accurate if about 20 points are already defined and should increase in accuracy the more points are defined.

Please offer at least one of both soloutions and shortly describe your plan how to solve this.

Hello, I think this can be done by creating a polygonal grid with lat/long known for each vertex. It can be constructed by texture-mapping the grid with your image and adjusting it to e.g. Google Maps screenshot. Or Más

x = (total width of image in px) * (180 + latitude) / 360 -- y = (total height of image in px) * (90 - longitude) / 180 -- THEREFORE -- latitude = ((x*360) / image_width)-180; -- longitude = ((x*180) / image_wi Más

Looks like fun. I have drafted about 80% of the solution. I think we'll benefit incorporating both options. Initially I'll lay out a lat/long grid based on the camera parameters. Next, the grid will be mapped onto the Más

You problem is far from trivial, hence the amount of our bid. We have a very good experience of that kind of measures, with distortions, perspective, etc. Among this, we process all sky fisheye cameras, a really extr Más

If you have at least three points, for which you know its coordinates, you can find coordinates for each points

Hello, This problem doesn't actually have an exact solution because the terrain is not flat. So each screen x,y actually translates into a line of latitude,longitude points at different heights. Without knowing the Más

Hi, I am keen work in this project since I have a good interest in the localisation. I prefer option 2 but I dont think we will need 20 points provided we can get some info about the camera. e.g Camera position, al Más
