Running the Demonstration
XAPP794 (v1.3) December 20, 2013 www.xilinx.com 18
The FOV measurements are shown in Figure 16.
A lens calculator (such as w
ww.1stvision.com/lens/lens_calculator) can determine the FOV
and, consequently, the ideal lens choice for a specific application.
Using the Text-based Console
The Linux camera demonstration application accepts commands from a text-based console.
Type the help command to list the supported commands. The Linux application also has a
web-based GUI that significantly improves the ease-of-use and is described in Using the
Web-based GUI.
