Dear users,
Speaking of clean interiors the main successful method is using either laser scans or a combination of photogrammetry and laser scans. As some of you cannot afford a laser scan you can always try using just photogrammetry but you need to understand that shooting a clean surface mostly featureless won’t always end up well, so this is not an issue of the alignment process itself as a subject should be picked well first. Anyways as you guys have noted yes you can use some patterned papers, stickers,etc. to make for some features and get a successful alignment. When using this technique you can as well shoot the interior clean and then shoot it again without moving any objects with the “stickers”. Then once you’re happy with the result you can use the clean images to texture it. Image layers function can be put to a good use here for example, or you can do it manually, that’s up to you.
