Cinematographic User Models for Automated Realtime Camera Control in Dynamic 3D Environments

Abstract: Advances in 3D graphics technology have accelerated the construction of dynamic 3D environments. Despite their promise for scientific and educational applications, much of this potential has gone unrealized because runtime camera control software lacks user-sensitivity. Current environments rely on sequences of viewpoints that directly require the user’s control or are based primarily on actions and geometry of the scene. Because of the complexity of rapidly changing environments, users typically cannot manipulate objects in environments while simultaneously issuing camera control commands. To address these issues, we have developed UCam, a realtime camera planner that employs cinematographic user models to render customized visualizations of dynamic 3D environments. After interviewing users to determine their preferred directorial style and pacing, UCam examines the resulting cinematographic user model to plan camera sequences whose shot vantage points and cutting rates are tailored to the user in realtime. Evaluations of UCam in a dynamic 3D testbed are encouraging.

Remote presence system including a cart that supports a robot face and an overhead camera

Abstract: A tele-presence system that includes a cart. The cart includes a robot face that has a robot monitor, a robot camera, a robot speaker, a robot microphone, and an overhead camera. The system also includes a remote station that is coupled to the robot face and the overhead camera. The remote station includes a station monitor, a station camera, a station speaker and a station microphone. The remote station can display video images captured by the robot camera and/or overhead camera. By way of example, the cart can be used in an operating room, wherein the overhead camera can be placed in a sterile field and the robot face can be used in a non-sterile field. The user at the remote station can conduct a teleconference through the robot face and also obtain a view of a medical procedure through the overhead camera.

Systems and methods for managing live video data

Abstract: Described herein are systems and methods for managing live video data. These include the likes of video management systems, camera servers, methods for providing access to video data, methods of operating camera servers, and software for allowing the implementation of such methods in a computer system. In overview, a video management system is configured such that, upon the failure of a camera server, cameras assigned to that server are automatically reassigned to a backup camera server.

Directed attention digital video recordation

Abstract: A system and methods of incorporating detailed snapshots of targeted areas of interest into a video or digitized recording of the overall scene including metadata to link the snapshots to the time and location in the overall scene from which the snapshot was acquired. A single fixed high-resolution scene camera or a fixed standard resolution scene camera of analog or IP connected type is used, co-located with at least one pan-tilt-zoom (PTZ) camera or by using the same scene camera in a mode where less than full resolution of the scene camera is used for video but snapshots of areas are captured by the same camera where higher resolution thereof is used for snapshots than for video. The area of interest is selected by the object-tracking feature of an intelligent video system, operated without human intervention, by electronically-implemented identification of the existence of area-specific subjects or targets of interest in the scene image field.

Deploying a network of smart cameras for traffic monitoring on a city kernel

Abstract: A relevant aspect when evaluating the city smartness is related to the innovative approach to urban traffic management We present a system called city kernel, designed to handle several subsystems, each addressing a specific sensor network and we describe an infrastructure for wide traffic control via a vision sensor network This infrastructure consists of a network of smart cameras operating over an outdoor public lighting thanks to power line communication technology and equipped with a vehicle counting and classification algorithm We discuss the deployment of this network on the city kernel and some related services exposed to urban actors
