Virtual camera

I have a quick question: I need a camera in a hostile (hot and sooty) environment. Is it possible to use cameras outside the hot zone and calculate an image as if it is from a virtual camera in another place? https://picload.org/view/dgpplpwl/vca...

I read something about view morphing: " Image morphing techniques can generate compelling 2D transitions between images. However, differences in object pose or viewpoint often cause unnatural distortions in image morphs that are difficult to correct manually. Using basic principles of projective geometry, this paper introduces a simple extension to image morphing that correctly handles 3D projective camera and scene transformations. The technique, called view morphing, works by prewarping two images prior to computing a morph and then postwarping the interpolated images. Because no knowledge of 3D shape is required, the technique may be applied to photographs and drawings, as well as rendered scenes. The ability to synthesize changes both in viewpoint and image structure affords a wide variety of interesting 3D effects via simple image transformations."

Seitz, Steven M., and Charles R. Dyer. "View morphing." Proceedings of the 23rd annual conference on Computer graphics and interactive techniques. ACM, 1996.

Here is an implementation for opencv: https://github.com/eroniki/viewMorphing

Hope it helps
