Stereo vision system
By Staff -- Test & Measurement World, 10/1/2006
Designed as a drop-in replacement for its predecessor, the Bumblebee2 stereo vision camera system from Point Grey Research acquires 48 frames/s at a resolution of 640x480 pixels (VGA) or 18 frames/s at a resolution of 1024x768 pixels (XVGA), depending on the model. Both models come in color and monochrome versions with a choice of 3.8-mm or 6.0-mm focal length lenses.
The binocular Bumblebee2 employs two 1/3-in. progressive-scan CCD sensors and transmits both the left and right images to a PC via an IEEE 1394 interface. The system is precalibrated for lens distortions, and the left and right images are aligned within 0.05-pixel rms error. Calibration files are embedded in the camera allowing the supplied software to retrieve the image correction information.
The included Digiclops and Triclops software development kits enable you to control camera settings, adjust image quality, and access real-time depth range images. Sample programs and source code are also included.
