Camera-based calibration of projectors in autostereoscopic displays

摘要

In a method of calibrating a projector in an autostereoscopic display a projector is used to project an image, comprising a plurality of objects, via a spatial-resolution-to-angular-resolution-converter. The image is received using a camera disposed at the viewer side of the spatial-resolution-to-angular-resolution-converter. It is then determined that a first object of the plurality of objects is not correctly aligned with a second object of the plurality of objects and the first object is re-aligned relative to the second object by generating a command causing the projector to shift the projection of the image relative to the spatial-resolution-to-angular-resolution-converter.
