Abstract
Three-dimensional (3D) projection display is an effective approach to
realize large size 3D images with high resolution. An autostereoscopic 3D
projection display is proposed. It consists of four projectors, a projection
screen, a lenticular sheet and a parallax barrier. Operation principle and
calculation equations are described in details and the parallax images are
corrected by the means of homography. A 50-inch autostereoscopic 3D projection
display prototype is developed and it presents good stereoscopic images. The
normalized luminance distributions of the viewing zones are measured, and
the results agree well with the designed values. Compared with the conventional
autostereoscopic 3D projection display based on two parallax barriers, the
proposed prototype has much higher brightness.
