Abstract
The aim of this article is to present a simple method which simplifi the laborious realization of an architectural photomontage thanks to powerful computer graphics techniques available nowadays. The proposed strategy is based on a simple data capture: it is only necessary to know the relative position of the point of view of the photography and the position of four points of the environment. It is easy to reproduce the scene, we can obtain an image of the future building from this point of view, placing the picture plane as interest us. Knowing the homography between these two planar images, controlled by the relative position of these four points, it is very easy to combine both pictures in the photomontage. Obviously this procedure is combined with proper attention to factors of sunlight and lighting and obstructions, to fi obtain an architectural image of modifi reality.

Notes
- 1.
Which is usually performed in the film scenery.
- 2.
We must know that a few years ago we hadn’t graphics software (as for example PTlens), which corrects automatically the optical distortion of the photograph depending on the model of camera (and lens).
- 3.
By the same procedure metric data base has been taken in order to draw the volumes of surrounding facades. All these measures are available with a GPS.
- 4.
This operation is performed by the software automatically by introducing a solar light.
- 5.
As we know, using the tools of the computer we can create a homographic image.
- 6.
The introduction or the deletion of shadows of our building (on the environment) can be done by changing the color of the pixels because a lot of software incorporates a color analyzer.
- 7.
Finally, as we know, there is also the possibility of transforming the image of a photomontage result, as seen in Fig. 6, by manipulating the geometry of the photographic image, for example to accentuate the verticality and horizontality of the picture. The homography also allows these transformations in which the result is not really a conical projection, but a second projection (cylindrical or conical) of the image.
