VK8 camera specifications

The following table provides technical specifications and performance indicators for the VK8 camera. Superscripted numbers indicate additional information provided in the VK8 specification table notes.

VK8 specification table notes

1. Increased frame rates: Above 150 fps, the amount of light emitted per frame is linearly reduced. The light emitted per frame at 300 fps is half that output per frame at 150 fps. (The total strobed light output remains the same). Selecting a frame rate greater than full resolution automatically reduces image size by windowing. This keeps the pixel rate the same by transmitting a greater number of smaller images per second. You specify the capture frame rate of the Valkyrie cameras in the Vicon application software. Valkyrie cameras are capable of capturing up to a maximum of 2,000 fps, but the actual frame rate you can specify depends on the Vicon application software you are using. For details, see your Vicon software documentation.
2. Shuttering: The global shutter overcomes the negative effects of using rolling shutters for motion capture.
3. Full marker grayscale: Marker centers are calculated based on every pixel of grayscale available for the marker, not just the detected marker edges. An on-camera circularity test ensures merged or partially occluded markers which need high-level processing are sent in full grayscale to the Vicon Valkyrie host PC.
4. On-camera masking: This removes areas of the sensor where undesirable static light sources are recorded, for example strobes from other cameras.
5. Blob elimination: Camera firmware automatically removes undesirable image data including both large blobs (e.g. sunlight reflections) and/or an unusually large number of blobs.
6. Output modes: Automatic (centers for circular markers, grayscale for overlapping/partially occluded markers), Centers Only, Grayscale Only, Centers/Grayscale, and Preview (the entire sensor image).
7. Preview mode: The full image is lightly filtered, decimated and transmitted to the Valkyrie host at 30 fps (variable). This reduces the quantity of preview video data to a level that can be transmitted over Gigabit Ethernet to the Vicon Valkyrie host PC.
8. Vicon Firmware Update Utility: Accessible either as a standalone application or through your Vicon application software (via an icon on the toolbar or from the Help menu).
9. Operating temperature: While Vicon cameras may operate outside the given limits, these are the temperatures to which Vicon has tested the cameras. If the cameras are operated outside of these limits, image quality may be degraded, the external surface temperatures may exceed the relevant safety limits, and any failures are not covered under warranty.
10. IP65 rating: Only applies if the lens cover and IP65 cable cap are correctly fitted. If the lens cover and/or cable cap are not present or are incorrectly fitted, the camera is not IP65-rated.
