3.3.3 Live Video.
Clicking the Live Video button, circled in the following image, allows the user to receive and view the data stream from
an input sensor as the area of interest is viewed.
For detailed steps in the use of the Live Video for use in lens focusing and scanning, please see the Lens Focus section of
this document. The following steps give an overview of the application and its control features.

The Hyperspec
III Live Video option provides users with multiple viewing and analysis features to accurately define the
AOI and system performance.
(1) The top row of the Live Video window has both buttons, to use features, and input boxes for configuring the
operation of the video stream. The first two buttons respectively magnify (Mag +) and reduce (Mag -) the
captured image as it is shown in the viewing area. The X-Hair button opens a red cross hair in the waterfall
display. The X and Y boxes along the top of the window relate to the Spectral and Spatial resolution shown in the
two graphical fields on the right and bottom of the Target window. The Autoscale and Snapshot buttons allow
the operator to respectively resize the window and select a single image of the dynamic display.
(2) The block in the lower right corner of the Live Video window contains the Field of View (FOV) calculator which
then populated the Exposure time and Frame period for the video selection.
(3) The Min. and Max. slider controls, under the FOV Calculator, are used to adjust the input resolution of the video
viewing window.
3.3.4 GPS.
The GPS functionality of Hyperspec
such as an aircraft or UAV. The full functionality and configuration steps are found in the GPS INS Operations section of
this book. A brief overview is provided below.
The GPS options, when connected, provide the user with the ability to initiate data capture at a specified point that the
system reaches and continue the capture through either a line or polygon area. Since the Headwall hyperspectral unit
would be moving on either a surface or aerial platform, the GPS unit can initiate capture as well as track capture locations
and terminate capture once an endpoint is reached. The scan results can then be used to develop a full spatial display for
the collected data. This is done through the ortho-rectification process, built into the Hyperspec
Figure 3-19. Live Video.
