Abstract:
Methods and systems are disclosed for controlling the focus depth of a 2D projected image on a pixel by pixel basis or on a region by region basis to create a 3D projected image that may be used for a heads up display (HUD) for augmented reality applications. The 3D projected image may be overlaid or combined with a 3D real world view using multiple reflective LCD arrays. The multiple reflective LCD arrays may receive a 2D projected image and may generate different length optical paths that may add depth to the 2D projected image to create a 3D projected image. The 3D projected image may be combined with the real world 3D image to create a 3D image encompassing a real world image and a 3D projection image that looks real and contains depth within the image.
