Photogrammetry generates actual three dimensional images, not merely appearances of.
- jay_kyburz 10y agoIf if you want to pedantic, all images are by definition 2 dimensional and can only appear 3D
- kctess5 10y agoI believe that photogrammetry can reconstruct 3D geometry, especially with the help of range sensors like the article mentions. The process results in 3D information like triangle meshes in addition to 2d images.
- greendestiny 10y agoYeah but in defence of the guy you're replying to, once you render them they are 2d images.
- Joeboy 10y agoAnd before that they're 3D models.
- sosuke 10y agoI keep finding photogrammetry papers discussing how to get the sizes of objects from photos. But those look like photographs and yet somehow seem unreal. Do you know any good intro to the subject? Something that would show a regular photo and the photogrammetric side by side?
- greendestiny 10y agoYou can try it yourself with commercial software: http://www.123dapp.com/catch http://www.123dapp.com/catch Scale can be hard to capture in photogrammetry, but in general the unrealness probably has more to do with the somewhat smoothed out (triangulated) surface that doesn't capture too fine a level of detail and the textureless (uncoloured) model they are rendering.
