Multi-projector three dimension display is a promising multi-view glass-free three dimension (3D) display technology,
can produce full colour high definition 3D images on its screen. One key problem of multi-projector 3D display is how to
acquire the source images of projector array while avoiding pseudoscopic problem. This paper analysis the displaying
characteristics of multi-projector 3D display first and then propose a projector content synthetic method using tetrahedral
transform. A 3D video format that based on stereo image pair and associated disparity map is presented, it is well suit for
any type of multi-projector 3D display and has advantage in saving storage usage. Experiment results show that our method
solved the pseudoscopic problem.
