Photomontages define the composition of three-dimensional modeling with photographic images. They can be used for a number of purposes, from creating stunning marketing images to supporting planning applications. They involve a collaborative skill set which combines 3D and image manipulation. The output is a product which delivers simply stunning results.
Photomontage techniques can also be used to produce sequences which combine real-life footage with animation. Utilising tracking software, the camera path of a video can be decrypted to provide our software with an animation route. This could include video shot from the ground or even from a helicopter. Compositing the footage alongside the three dimensional model we are able to produce output videos which have all the benefits of a photomontage image in an animated format.
Verified Views
Verified views are used to accurately demonstrate the visual impact of a development. The preparation of the verified views involves a survey in order to prepare highly accurate information on the heights of existing buildings and features.
A verified photomontage is a high quality rendered image in which the relationship between the camera position and detail in the photograph is known. Once the photograph has been aligned to the geo-referenced information the 3D model of the development can be inserted to correct scale and location.
The camera location, building and feature information is used to control the photo alignment. The position from which the photography is taken is surveyed and rigorously documented. Features that appear in the photograph are also surveyed on the same co-ordinate system so that their position relative to that of the camera is known. These are surveyed and calculated from the control stations.
The building and feature details are generally captured using one of two methods, namely polar observations or intersection observations. These methods yield a result, accurate to 20mm-50mm.
Once the data and photography has been captured it is combined in specialist software in which the photograph is aligned to the points of detail. The 3D model of the proposed new development can then be inserted into the scene at the correct location to give a perspective view of the development.
Verified views tend to be concentrated on the immediate vicinity of the site where the impact will be likely to be most significant to the domain.
