METHOD FOR SEPARATING LOCAL AND REMOTE CONTENT IN A CAMERA-PROJECTOR BASED COLLABORATIVE SYSTEM

An image processing method, for collaborating between a first augmented reality (AR) workspace and a second AR workspace, includes: calibrating the first AR workspace by creating a camera-to-shared space transformation between a camera coordinate space and a shared coordinate space, and a shared space-to-projector transformation between the shared coordinate space and a projector coordinate space; obtaining a remote composite image of a foreground content in the second AR workspace; generating a projector image by applying the shared space-to-projector transformation to the remote composite image; projecting the projector image into the first AR workspace; obtaining an input image of the first AR workspace that includes the projector image and a foreground content of the first AR workspace; generating an output image by applying the camera-to-shared space transformation to the input image; and obtaining a remote mask based on the remote composite image.
