System 3 8-33
RVMap Software for RV2
Reference Points and Range
The units/scaling of the workplace and all X, Y coordinate values returned by the
tracking algorithm are determined by the following image window
Reference Points
:
red star blue star
By default, the red star and blue star Reference Points are positioned, respectively,
in the bottom left and top right corners of the image. The red star defines the center
point (0,0) and the blue star defines the position of the (X,Y) range value in the
Settings dialog.
After the range values have been defined, click OK to apply them to the RVMap
settings.
The
Reference Points
can be dragged to a new position, such as the location of a
known object in a displayed image, to help define a real-world scale for the image.
For example, a ruler might be placed in the camera frame and the Reference Point
can be dragged to each end of the ruler so that the X,Y coordinates will be
redefined based on the ruler visible in the image.
To select and move the
Reference Points
simultaneously:
• Hold down the CTRL key and click each of the
Reference Points
. They are
now both selected and both will move in unison.
Camera Settings
The Camera Settings area of the Settings dialog box enables user to retrieve settings
from the camera so that they can be stored with the configuration and applied each
time that configuration is used. The RV2 does not maintain the camera settings after
it is rebooted, so it is a good idea to store the current settings in the configuration
file. The values you see initially are the default values.
To retrieve the camera settings to be applied each time the configuration is
loaded:
• Click Fetch From Camera .
The Live tab on the RV2 interface provides an AutoOnce button that tells the camera
to perform its own auto-adjustment of exposure, gain and white balance. The Lighter
and Darker buttons on the Live tab are used to adjust the exposure time. There is
no direct control of gain and white balance on the RV2 interface, so if you want to
manipulate those values you will have to adjust them in the Settings dialog and
upload the configuration to the RV2 to apply those camera settings. See “Saving
Configurations” on page 8-31, for more information on uploading the configuration.
