Page 13 - 3DF Zephyr

In Additional options (4) the Check online for precomputed camera calibration option allows to save camera calibration parameters on a 3DF Zephyr online database so that the software will be able to automatically get that providing the exact calibration parameters and reducing the timing of Structure from Motion phase, when that camera will be exploited again. In the previous submenu, you can also load the masks related to photographs, if these have been previously generated with the 3DF Masquerade tool. After clicking Next the Masking page will appear(see image above) and it will specify whether the masks have been properly loaded into 3DF Zephyr (a green "Ok" should appear close to the picture's name, for each imported mask) or not.
