Augmented reality mobility
Motivation
MotivationTwo consistency
Geometric consistency Devices Camera position
GPS, UWB, Omnisense WiFi, cell information
Camera pose Linear accelerometers
Tracking via computer vision [Cornelis et al. LNCS 2001, zhang et al. CVPR 2007, Xu et al. image
and Vision Computing 2008]
Illumination consistency outdoor lighting is largely dependent on
weather and time
MotivationTwo problems
