Color Stereo Camera

bumblebeeThe Bumblebee®2 from Point Grey is the next generation Bumblebee® stereo vision camera. It provides a balance between 3D data quality, processing speed, size and price. Developed as a drop-in replacement for the original Bumblebee camera, the Bumblebee2 also features double the frame rate and a GPIO connector for external trigger and strobe functionality.

The camera system is provided as a complete hardware and software package. Stereo depth information is calculated by software on the robot's onboard computer.  All hardware and software components are provided preinstalled, calibrated, tested and ready to use.

Every system includes the FlyCapture SDK, which is used for image acquisition and camera control, and the Triclops SDK, which performs image rectification and stereo processing. Additional stereo vision software components are available at no extra cost: the Censys3D SDK, which is ideal for people tracking; and the Multiclops software, which allows integration of multiple cameras into a single coordinate system.
