Abstract

Mobile Internet devices may be used to generate Mirror World depictions. The mobile Internet devices may use inertial navigation system sensor data, combined with camera images, to develop three dimensional models. The con of an input geometric model may be aligned with edge features of the input camera images instead of using point features of images or laser scan data.
