Hello jknox,
Here are some recommendations, but they could be applied not only for interiors:
- provide good lighting conditions for the interior (indirect diffuse light is preferred), we suggest that windows should be covered, since they produce high contrast and can not be reconstructed anyway due to transparency;
- avoid blinking and mirror surfaces - they are problematic for reconstruction (almost impossible) and may induce false matches into the camera alignment, transparent objects can not be also reconstructed;
- PhotoScan works well with finely textured objects, whereas untextured, plain surfaces without any features (like metal/plastic objects or object parts) could not be reconstructed correctly, so you may encounter problems with untextured white walls;
- another type of problematic object type is thin objects like pipes;
- use minimal possible ISO value to prevent additional noise on photos;
- provide sufficient focal depth to capture details of scene, blurred images will be almost useless, probably you should use tripod;
- provide sufficient overlap between images but do not take photos from the same location just turning camera around - it's much better to step aside;
- note that areas that are not seen from at least two photos will not be reconstructed correctly;
- using fixed lens is preferred, for zoom lens we recommend to use only minimal or maximal positions and avoid intermediate focal length values.
