Original Abstract Submitted

a system for correcting for frame bending of an augmented reality system is provided. a combination of strain gauges and visual inertial odometry is used to determine strains in the frame. an initial model between strain gauge measurements and actual frame spatial relationships is based on finite element analysis or calibration. during an initial visual inertial odometry data calculation phase, the augmented reality system calculates bending or strains of the frame using strain data from the strain gauges mounted to the frame. subsequent visual inertial odometry data calculations are used to generate a corrected frame model of the frame. the corrected frame model is used for calculating corrected tracking data and corrected virtual overlays that are used to generate virtual overlays used in an ar experience provided by the augmented reality system.
