Interesting post Shaan, thank you. - And wild software. Question: I see that you noted that Project Photofly and a laser scanner technology are different and complimentary. It is my understanding that point clouds created by 3D laser scanners take into account the horizontal and vertical angles between the item being scanned and the scanner itself. By doing so, horizontal and vertical distortion are removed, and a true scale point cloud results. ...So I’m guessing that Project Photofly doesn’t account for distortion, and is therefore good for rough 3D models, but couldn't be used as true scale 3D technical drawings (e.g. engineering drawings, etc.)?


I will go into more detail in a future post but you can get very accurate scaled vertical and horizontal axis geometry using Project Photofly although depning on your photos and lens perhaps not as high point density as a laser scanner, but fine for most uses especially if you do not have access to a laser scanner. There are algorithms that take into account distortion as well you can place manual calibration points and reference dimensions for known geometry. Give Project Photofly a try.


Hmm, this is getting more interesting. Part of what I do for a living is creating 2D AutoCAD building elevation drawings for facade repair projects. Typically semi-scale drawings are what is required by the AEC professionals that I service. For any given building, taking a few field measurements and photos enables me to create such a 2D drawing back at my PC. There is occasionally the situation, when a more detailed 2D drawing is required. For instance, like the phone call I received this week from an Architect looking for detailed 2D drawings of a mildly ornate church here in NYC. So... Could Photofly be realistically implemented in such a scenario, to create 2D drawings, as a substitute for 3D laser scanning?
