Panorama Camera Match
We use 3Ds max to produce photomontages of proposed plant developments for the energy industry.
We model the development and then try to match it the best we can to a background image. This can be either a single photograph or a stitched panorama photograph. The field of view we have to cover is anything up to 180dgrees.
These images are not for interactive QTVR/ Panotour type output. Our end product is for flat printing for the purposes of public exhibition and environmental impact assessment reports. These photomontages are required to be verifiable and to match the geometry and perspective of the camera used to take the stitched images.
When matching to a wide-angle panoramic stitch we are finding it more difficult as we cannot find a way of getting 3d Max to have a projection output that matches the background image accurately.
Does anyone know of any techniques or Scripts/plugins that would allow 3D max to project/match a model correctly against a panoramic image? Or are there any other programmes that anyone knows can achieve this?
We know it is technically, computing wise, possible as we use a programme called ‘Windfarm’ for wind turbine site assessments. This programme allows you to match model and DTM to up to 180 degree stitched panoramic images. It also takes into account earth curvature and atmospheric refraction. Unfortunately this programme cannot import other custom non wind turbine models.
In some methodologies there is a mention of VRAY using the physical camera set to cylindrical projection. We have down loaded the demo and are finding that the ‘Warped Spherical (Old style)’ projection seems to create a nearly convincing effect.
We are finding however that the overall width of the projection does not quite fit the position of existing objects in the panoramic image. This may be because the GPS data measurements are not accurate enough for the purpose. However we are trying to demo the ‘.lens’ file facility to see if that will help.
Does anyone know if using VRAY is the correct answer to this image matching problem? If so can you offer any advice that should theoretically make VRAY match exactly the geometry and perspective of a wide angle stitched panoramic photo?
Thanks in advance for any help.
