While the Dragonfly®
camera conforms to the DCAM standard, many of its features are above and
beyond this standard! This newsletter presents new and less known features
of the Dragonfly®.
Dragonfly® has three
header pins that can be configured in one of
four ways: external
trigger, strobe output (CCD integration time start signal), digital input
and digital output. By using these pins, it is possible to set up sophisticated
interfaces with devices that the Dragonfly® works with. The camera can be
synchronized to external events or external devices can be synchronized to
the image acquisition of the camera.
The B&W Dragonfly®
has a special mode in which it is possible to acquire 640x240 images at 50FPS.
Vertically adjacent pixels from the original image are averaged in order to
reduce the aliasing. The automatic camera synchronization is maintained in
Dragonfly® can be
put into a special mode where the integration time can be extended up to
several seconds. This feature is particularly well suited for low lighting
to multiple cameras
distributed with the Dragonfly® allows the user to simultaneously broadcast
the same message to multiple cameras. Software triggering for image acquisition
and camera parameters can be broadcasted to all cameras on the bus with one
For customers that
do not plan to embed the Dragonfly® into their own products, Point Grey has
developed a CS mount camera housing unit. The unit is made from machined
aluminum and is available with or without IR filters.
16-bit images for applications in which greater depth of pixel is required.
10 bits of the transmitted 16 bits are significant allowing the camera to
have over 60dB signal to noise ratio.
For tough to get
to places, the extended CCD version of the Dragonfly® is a great solution.
Example source code
Dragonfly® is provided
with a number of example programs in source code format. The popular "matrix-like"
demo application is also provided with source code. Click here for
Matching synchronized images
While the images
acquired by multiple Dragonfly® cameras are automatically synchronized, the
challenge is to determine which image matches which one. A practical solution
to this problem is to put the Dragonfly® cameras into a special mode where
the first four pixels (top left) are actual "rolling" counters. If the pixel
values of the images from different Dragonfly® cameras match up, you are guaranteed
they have been acquired at the same time.
