NDI PolarisVega -Model VT -Optical Tracker for Augmented Reality Applications
Our specialized optical tracker, the Polaris Vega VT combines accurate optical measurement and live video streaming; these capabilities can be used for developing augmented reality and machine vision for OEM surgical system workflows. As with all Polaris optical trackers, the Polaris Vega VT can track OEM surgical instruments via navigation markers. The HD video camera provides a live view of the instruments (and procedure occurring within the measurement volume) using a third-party streaming client.
Exceptional Measurement Accuracy
The Polaris Vega VT delivers volumetric accuracy to 0.12 mm RMS at 60 Hz, with minimal noise while streaming video. Track with confidence; hardware characterization and factory calibration optimize accuracy for measurements that are highly repeatable and reliable.
- Volumetric Accuracy1,2 RMS : Pyramid Volume: 0.12 mm
- Extended Pyramid: 0.15 mm
- 95% Confidence Interval1,2 : Pyramid Volume: 0.20 mm
- Extended Pyramid: 0.30 mm
Integrated HD Video Camera
The Polaris Vega VT video camera provides a live view of the measurement volume via third-party streaming clients. Camera resolution, frame rate, and other features can be quickly configured in-field to capture sharp, high-contrast images in most operative environments.
- Resolution : Frames per Second : Horizontal Field of View : Vertical Field of View
- 2048 x 1536 : 20 max. : 54.8° : 42.5°
- 1920 x 1088? : 30 max. : 51.8° : 30.6°
- 1024 x 768 : 47 max. : 54.8° : 42.5°
Augmented Reality Overlay
The Polaris Vega VT software enables a live augmented reality overview of tools within the video stream, which is aligned to the IR data coordinate system. Create virtual tools and new video-enhanced applications using the built-in API and available software and source code.
- Tool Types : Passive, Active Wireless
- Maximum Number of Tools : Load up to 25 tools (maximum of 6 active wireless)
- Maximum Number of Markers per Tool : 6 single-face/20 multi-face
Seamless Data Synchronization
The Polaris Vega VT uses the Precision Time Protocol (PTP) for network synchronization and the Real-Time Streaming Protocol (RTSP) for streaming video. Tight data communication and synchronization are achieved by Gigabit Ethernet, and system power via POE (Power over Ethernet).
- Measurement Rates : 20, 30, 60 Hz
- Average Latency : < 16 ms (typical) at 60 Hz
- Data Communication : Gigabit Ethernet
- Video Streaming Protocol : Real-Time Streaming Protocol
