Application of large-head-box canopy distortion compensation scheme for improved cueing and targeting precision

Canopy distortion occurs when a pilot is looking through any curved aircraft transparency. Any helmet mounted display system must either compensate for this distortion, or incur canopy distortion error in its total error budget. Thales Visionix has applied a novel method for characterization of and compensation for aircraft canopy distortion, allowing for views from any position within a large head box. We present techniques allowing for compensation of canopy distortion for the entire HMD head-box, and implications observed based on applying these techniques for A- 10 and F-16 canopies
