Point Grey Research Announces New People Tracking Application Using its Triclops 3D Stereo Vision System


October 4, 1999 – The people tracking application provides the ability to count people within a given area of interest, tracking the direction of their ingress and egress, monitoring the flow of traffic, and providing accurate counts within short increments of time. The system has been tested to an overall 90-95% accuracy. The people tracking application is based on Point Grey's Triclops Stereo Vision Camera System, which is widely used in capturing 3D range data for use in robotics, industrial vision, and measuring applications.

"We developed the people tracking application to be highly accurate and robust," said Rod Barman, President of Point Grey. "With this application, there are virtually no calibration issues, and it is suitable for indoor or outdoor installations, day or night" he said.

The counting of people has traditionally been done using beam or sensor technologies. Point Grey's people tracking application may be unobtrusively positioned to monitor people in the area, and its small size, assists in concealing the unit. The camera's ability to capture range data from a variety of angles provides flexibility in the placement and positioning of the camera.

The Triclops people tracking application is designed to work in a variety of unstructured environments, where people counting is made difficult by shadows, changing lighting conditions, height and awkward angles, and occlusions caused by people moving closely together. The Triclops application uses 3D data to distinguish individuals within a scene, and track them as they move through the monitored area. With no dependence upon the intensity of the image, and using the 3D data, Point Grey's people tracking solution provides superior accuracy to any single-lens video, sensor or beam people counting system.

Triclops is a commercially available stereo vision camera that provides high quality 3D video imaging capabilities for a variety of applications. Triclops cameras are sold to customers throughout the world.

Point Grey Research is a worldwide leader in the development of advanced digital camera technology products. Based in Vancouver, British Columbia, PGR designs, manufactures and distributes IEEE-1394 cameras, stereo vision cameras and spherical digital video cameras to a broad spectrum of industries. Through a close working relationship with its customers, PGR continues to be at the forefront of innovation.
