Ramón Maestre López-Salazar, Pablo Jeremías Juan Gutiérrez
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.
