Steadicam-Setup für Echtzeit-Motion-Tracking mit HoloLens-Demonstration
Was die Diskussion ergab
- Ein benutzerdefiniertes Steadicam-System wurde entwickelt, um zu verfolgen und anzuzeigen, was ein HoloLens-Gerät in Echtzeit sieht, was mehrere Sensoren und Datenfeeds erfordert, die über ein einzelnes Kabel übertragen werden.
- Das System kombiniert eine RED Dragon-Kamera, eine HoloLens-Optik und einen Xbox Kinect-Tiefensensor auf einem einzigen Rig, wobei die Ausgabe mit einer Verzögerung von einer halben Sekunde mit holografischen Inhalten verarbeitet und überlagert wird.
- The transmission system requires 3G SDI video output and return signals along with optical Thunderbolt, single-mode fiber, sync signals, and power, necessitating a thick cable bundle from operator to sled.
- Initial demonstrations were limited to 25 feet of tether distance due to 3G SDI bandwidth constraints, with the server processing equipment positioned nearby.
- Extending range to 100 feet was achieved by converting SDI signals to multimode fiber with media converters powered by a portable USB battery pack worn by the operator.
- Sled-mounted power solutions must use voltage-regulated converters to prevent disruption to sensitive onboard electronics.
- The operator used a PRO/XCS Steadicam sled with Cinetronic monitor and relocated the cable harness from a shoulder tether to a shoulder-mounted configuration to reduce steering strain.
- MegaFlex SDI cables and fiber optics were used to minimize bundle size while maintaining necessary signal integrity over extended distances.
Hängt ab von
- The exact specifications and construction details are proprietary and confidential to Microsoft.
- The operator cannot share photographs or detailed technical schematics of the system.
- The setup was specifically engineered for demonstration purposes and may not be reproducible without access to the specialized components and engineering support.
- These systems represent experimental technology from the early stages of HoloLens development and may not reflect current commercial implementations.
