PPT-H
Use this plugin to configure the PPT-H cameras. The options available for
configuration are:
Frame rate:
The approximate number of frames per second that the camera will produce (+/- 1
frame)
Between 15 Hz and 180 Hz (use 60 Hz for long range tracking of dim markers,
otherwise 180 Hz is recommended)
Exposure duration:
The amount of time to capture light with the sensor before processing it.
5500 microseconds is recommended for the longest range 180 Hz tracking, but
smaller values are best for very fast motions.
Larger values will cause the frame rate slider to adjust to a lower maximum since
faster rates are not possible at that exposure time.
Brightness:
Apply an additive brightness shift to your PPT camera capture images.
Range from 0 to 255, 128 is the recommended default
Broadcast address:
The address to use when scanning for cameras on your local network. This will
typically be 255.255.255.255 for an automatic scan of all available network
interfaces. If you have multiple PPT-H configurations on separate networks, you will
need to specify this exactly.
2D PLUGIN
2D plugins are used to process the images that are received by the cameras, and are
responsible for placing the 2D crosshair over each marker. Note that only PPT-X
systems use 2D plugins - the PPT-E and PPT-H system includes the 2D plugin on-
board the camera, and so changing the 2D plugin has no effect in this case.
