Robust marker-based projector–camera synchronization

Recording clean pictures of projected images requires the projector and camera to be synchronized. This task usually requires additional hardware or imposes major restrictions on the devices with software-based approaches, e.g., a specific frame rate of the camera. We present a novel software-based...
