    Hi Fortfahren,

    yes it is absolutetly possible!

    A few notes:

    - photogrammetry does not work well with uniform or trasparent surfaces (as it needs to find where pixel (X,Y) in foto A is in foto B, C, D, etc, for all pixels). This means, do not clean the inside of your truck! Dirt and dust will work in your favor! (but remove clutter so you have only the surfaces you are interested in, so remove those cables for example if possible).

    - If you have plain, reflective or transparent surfaces, consider covering them with dust or with other textured material (e.g. newspapers?) . You don't need the texture after all, so you can go crazy in putting all kinds of stuff that can help you reconstruct the surface The window cover seems completely black, so i would remove it and put newspapers.

    - photo quality is very important: you have a tripod, so that's great. Avoid flash photography or direct light (to avoid reflections) and use a longer exposure to overcome this project

    - you need photos that are taken from different positions. You may be tempted to go inside, leave you camera at the middle of the scene and rotate it: you will get MUCH better if you have a lot of parallax, so move as you keep shooting. Do not to a nodal movement, but rather, "walk" alongside all the "walls" and take photos of the opposite one.

    - our full version is probably the best option for optimal result and accuracy, as you can also use control points and drawing elements. However, since this is a single project, you can probably still work with Zephyr Lite (i doubt the 50 photos limit of 3DF Zephyr Free will be good enough for you). Note that all reconstructions are initially in an arbitrary scale, so you will need something of known size in your scene in order to rescale it (it can be anything from the subject itself). CHeck here how to rescale with free or lite http://support.3dflow.net/support/so...-free-and-lite

    - the exported result is a triangular mesh. Make sure the application you wish to use the exported data with is compatible with one of the many formats we support (stl, obj, ply, and many more, the full list is available on zephyr.3dflow.net )

    if you have any question feel free to ask!
