ThirdEye: a coaxial feature tracking system for stereoscopic video see-through augmented reality

For stereoscopic augmented reality (AR) system, continuous feature tracking of the observing target is required to generate a virtual object in the real world coordinate. Besides, dual cameras have to be placed with proper distance to obtain correct stereo images for video see-through applications. Both higher resolution and frame rate per second (FPS) can improve the user experience. However, feature tracking could be the bottleneck with high resolution images and the latency would increase if image processing was done before tracking.
