Exploiting mirrors in interactive reconstruction with structured light

This paper describes how a mirror can be integrated as another view and another source of light pat-terns in an interactive reconstruction system with structured light, where the object, the camera, and the mirror can move. We show how a single pass of structured light can provide 3D points to accu-rately estimate the pose of a mirror, while also re-constructing 3D points on the object. We develop new structured light patterns that are unaffected by the reversed order created by some mirror configu-rations. We also describe hardware rendering sup-port to avoid conflicting emitted/captured light pat-terns, and demonstrate how all the proposed real-izations extend naturally for multiple mirror config-urations. We finally conclude with results, discuss limitations, and suggest further improvements.
