Not entirely sure what you mean, if you want to model the picture and then use the picture as a projection thant you would need to know the lense properties of the camera and then duplicate them onto the maya camera. Attach the image to the image plane attribute of the camera so that when you look throught it the pictures there

I would then suggest that you line up the grid with the floor, lock down the camera so that you cant move it accidentaly then model from there.

Hope this helps

To find the vanishing point of the image you need to find one object that is constant throught out image and maintians the same height.

The fence would be ideal follow that to its vanishing point. As Steve stated above, this is a standard picture taken with a 35mm camera. 35mm being the length between the lens and the "film" (ok i know its digital, but tis the same rule :p). Once you know its 35mm then away you go.

Really once the image plane is set its set to the camera, thats why steve said to lock the camera off. I do not think you can adjust the direction of the camera to point to the vanishing point, the original picture was not taken that way.

If you want to model this scene then:

Create a new camera
Attach the picture as an Image plane
Lock all the attributes in the channel box
You can use the camera to check your work and for final render

The fence is on a slope but it's minor. The theory is all lines that are exactly parallel must converge to the same point. Slopes just alter the altitude of the horizon line where the differences connect (think 2 or three horizon lines) so parts of the fence has different vanishing points vertically.
Find the parallel lines, the stairs for instance, or the part of the fence that isn't sloped, and trace from there. Should end up just left of your avatar roughly
