prostheticknowledge:Camera to PC Spatial 3D Data Method From Photos Project in early stages from Tokyo to quickly digitally reproduce 3D objects from photographs. What differs this to Autodesk 123 Catch is the photographic information is transferred locally to PC over Eye-Fi card as opposed to the cloud. From DigInfo News:A research group at Tokyo Institute of Technology is developing a system that quickly creates 3D spacial data from photos taken with a digital camera.“We take pictures using an ordinary digital camera. This camera has an Eye-Fi card, which sends the pictures to a PC wirelessly. This system uses the received pictures to rapidly create a 3D model. A feature of this system is that it doesn’t use any information other than the pictures to construct the 3D data.”“Other people are researching similar systems. What we’re specializing in is the online aspect. In other words, what’s interesting is, you see the results as soon as you’ve taken the pictures. For example, when aerial photos are processed after saving them, if you need to take more pictures, you have to go out again. But with our system, you can see on the spot whether 3D measurement was successful, so if you don’t have enough pictures, you can just take some more.”This system uses SfM, or Structure from Motion, which estimates the 3D shape and camera position from several pictures of the same scene. To reproduce spatial position data, it repeatedly identifies and matches characteristic points between two pictures.More information (including a demonstration video) can be found at DigInfo News here(PS - DigInfo has been great recently - worth checking regularly) -- source link
