Abstract:
1. An interactive three-dimensional (3D) display system, comprising: a three-dimensional display panel having an optical sensor array; an interactive device comprising a projection light source and a shadow mask, wherein the shadow mask has a pattern which defines an image projected by the interactive device, the image being captured by the optical sensor array, the pattern comprising two strip patterns which cross each other, and the image comprising two strip images which cross each other; and an image recognizing unit electrically connected with the optical sensor array, wherein the image recognizing unit calculates relative positions of the interactive device and the three-dimensional display panel according to the image captured by the optical sensor array, a method of calculating the relative positions of the interactive device and the three-dimensional display panel comprises: calculating the relative positions of the interactive device and the three-dimensional display panel according to a length of one of the strip patterns, a length of only one of the strip images, a divergent angle of the projection light source, and a tilt angle of the projection light source.
