Page 64 - 3DF Zephyr

This menu allows to access certain control points tools. Scale model with control points: same functionality exposed in the "Control points" tab. Scale with control distances: same functionality exposed in the "Measurements" tab. Show last alignment information: shows information about the latest "scale model with control points" operation. Change current coordinate reference system: allows to change the reference system of the project (only 3DF Zephyr Aerial). You must have already defined the reference system with control points before you can change the reference system Print Markers and markers use The following chapter will explain learn how to exploit coded targets in 3DF Zephyr in order to further improve the cameras orientation phase. 3DF Zephyr’s coded targets are square-shaped (see image below). In order to print coded targets just click on Tools in Zephyr’s menu bar and then on Control points and Distances > Print Markers. You can print up to 24 different targets. 3DF Zephyr supports 16 bit coded target: their size strictly depends on the kind of 3D reconstruction and the related photographic survey as well. Recommended settings are as follows: Close Range and Human Body 4 targets per sheet (A4 size) Urban 2 targets per sheet (A4 size) Aerial 1 target per sheet (A4 or A3 size) - You can define the amount of targets per sheet by editing the printing menu settings on Windows ( the term “page” implies a target inside that menu). It is recommended NOT to use coded targets randomly; instead it is highly recommended to use them in their own numerical sequence (1, 2, 3, 4, etc. and not 4, 13, 22, etc.)
