    Hello,
    if I am correct then the empty space in real world is a plain plaster wall. Photogrammetry recognises subjects with visible pattern or a structure detail, once you have a solid coloured wall without any special surface, RC will not be able to find contrast points on it and therefore no points in space. Normally you should pick suitable subjects, but if you want to continue with this interior, there are two possibilities.
    1. Place some patterned papers on the wall before scanning (markers, noise, spray freckles). There will have to be lots of them to cover most of the wall.
    2. Use a laser scanner in combination with the photos.

    I see, thanks for the advice. I shall try it out with placing some patterned papers.
