High-Performance Wide-Area Optical Tracking: The HiBall Tracking System
Since the early 1980s, the Tracker Project at the University of North Carolina at Chapel Hill has been working on wide-area head tracking for virtual and augmented environments. Our long-term goal has been to achieve the high performance required for accurate visual simulation throughout our entire laboratory, beyond into the hallways, and eventually even outdoors. In this article, we present r...
متن کاملImproved Optical Flow Algorithm for an Intelligent Traffic Tracking System
It is known that to get the contours and segmentations of moving cars is the essential step of image processing in intelligent traffic tracking systems. As an effective way, the optical flow algorithm is widely used for this kind of applications. But in traditional gradient-based approaches, in order to make the data responding to the edges of moving objects expand to the area, which gray level...
متن کاملApplying a Real-Time Interface to an Optical Tracking System
Computer-aided surgery is a young and exciting field of research. It is concerned with visualizing drills and other tools in relation to radiologic data allowing the surgeon to angulate these tools. Motion tracking hardware used in these applications provides high accuracy and update rates. However, current software implementations lack the important real-time constraints required for robotics ...
متن کاملAn Optical Pen Tracking System as Alternative Pointing Device
A webcam together with a standard pen can replace a mouse as pointing device for many common user interaction tasks. We provide an implementation of a dedicated image-processing component integrated in a ready-to-use software tool that acts as mouse alternative. The image-processing component is responsible for tracking the head of a pen based on shape and colour information retrieved in a quic...
متن کاملUWB/IMU Tracking Validation using an Optical System
Commercially available Ultra-Wideband (UWB) systems typically consist of a network of synchronized UWB receivers which track a large number of small, battery powered and inexpensive UWB transmitters. Reported indoor position accuracies lie in the order of decimetres, but suffer from multipath effects and non-line-of-sight (NLOS) conditions. These effects are most prominent while tracking moving...
