Beschreibung
Zusammenfassung:	An autostereoscopic helmet display comprising: a casing; an optical medium (20); a projector (30), projecting an original monochromatic image onto the optical medium (20); a camera (40), performing still image capture on the image projected on the optical medium (20) so as to generate a sample image; a processor (50), utilizing an image processing technique to calculate the vertical trapezoid base angle parameter θ of the sample image; a coordinate translator (60), sampling the coordinates of different pixel points of the original image, entering the coordinates and the base angle parameter θ into a pre-set formula, and changing the coordinates so as to generate an anti-distortion image, in order to address trapezoid distortion of the projection image. Also provided is a projection image trapezoid calibration method for the autostereoscopic helmet display.
