The accurate tracking of people is an ongoing problem in computer vision. It has applications in security, as well as business, manufacturing, and entertainment. Rather than monitoring people with a simple video feed, a computer vision system can track activity automatically and provide useful data. This stereo vision system allows a computer to locate multiple people simultaneously in 3-D space and
track their movements.
• Tracking people accurately is an ongoing computer vision problem
• Possible applications in security as well as many other fields
• System can provideuseful location and movement data
• Stereo cameras can detect object locations in 3-D space
The two cameras are fully calibrated, and the images are rectified.
A running average background is subtracted from each image, leaving just the foreground.
Points are triangulated and displayed in a top-down view.
