Cameras: Software: Triclops™ SDK
Point Grey Research's IEEE-1394 (FireWire) Stereo Vision camera systems are provided as
complete hardware and software packages. Every Point Grey Stereo Vision camera system includes a free copy of the FlyCapture SDK, which is used for image acquisition and camera control, and the Triclops SDK, which performs image rectification and stereo processing.

| Triclops™ SDK |
|
|
The Triclops™ Software Development Kit (SDK) is included with all Point Grey IEEE-1394 Stereo Vision products and is used to provides real-time depth range images using stereo vision technology. It allows users to accurately measure the distance to every valid pixel in an image.
*New features in Triclops SDK version 3.3.0.2*
Multithreading enhancements and first-ever Triclops 64-bit OS support on both Linux and Windows.
When combined, these improvements enable full stereo image rendering at frame rates and resolutions that were not possible before. Developers can leverage concurrency and memory architecture features found in new generation hardware and operating systems, resulting in frame rates 3 to 4 times faster than was achievable in previous releases on a single core machine, with the added benefit of 64-bit memory addressing.

| Stereo Algorithm |
- An area based correlation with SAD (Sum of Absolute Differences)
is done on band passed images.
- The algorithm is fairly robust and it has a number of
validation steps that reduce the level of noise.
- The method requires texture and contrast to work correctly.
Occlusions, repetitive features and specularities can cause
problems.
- Stereo can be performed with both 2-camera and 3-camera
stereo configurations

| Speed |
- This chart illustrates the speed of the Triclops™
SDK using a 640x480 B&W Digiclops® on a P4 2.4GHz
PC. The Digiclops® baseline is 10cm. The Bumblebee® baseline
is 12cm and is therefore more accurate.
- The disparity range was selected so that it corresponds
to a distance range of 0.5m to infinity
- The data was obtained using the demo program that is supplied
with the Triclops SDK
- The number of disparities is proportional to the speed.
Therefore, if you cut the number of disparities in half,
the system will run roughly twice as fast. The speed of
processing is independent of the mask size.
