When you capture optical data, subsampling (selectively reducing the pixel count) enables you to run at high camera frame rates without reducing the FOV (frame size). Nexus 2.11 and later supports the use of the Vantage+ firmware upgrade, enabling you to use High Speed mode on your Vantage cameras without having to change the field of view (FOV) or lens. Note: If you are using a mixed system (ie your Vicon system consists of a mix of MX T-Series cameras and other current Vicon cameras), and if it is crucial to your work that the shutter periods for all cameras are precisely aligned, ensure that your firmware is upgraded to version 700 or later, and set the Strobe Intensity for the T-Series camera(s) to its maximum.

However, especially when the capture volume is very small, this may be uncomfortable to the patient, so less than the full intensity may be the best setting.Īdjust this setting in conjunction with the Threshold setting until reflections are minimized or gone. Tip: In normal circumstances, it is advisable to use full strobe intensity and deal with reflection problems by closing the camera lens aperture. Lower strobe intensities mean that the markers are captured with the strobes on for less time and, therefore, have less time to move during the frame. The full strobe intensity corresponds to 1ms for normal frame rates. The strobe intensity affects the time the strobe is on for each camera frame. If you are capturing a very fast moving subject.If you see a lot of reflections in the volume, either from other cameras or from other objects in the room, such as shiny equipment, floors, or from the subject.However, there are two significant cases where you may want to lower the intensities: In almost all circumstances, you will want to keep the intensity at its maximum level because the system works by recording light from the strobes that is reflected from the markers, thus the more light the strobes send out the more light the markers reflect. Lower settings reduce unwanted reflection sources but make the markers themselves less visible to the Vicon cameras. The higher the setting, the larger the markers appear, but this may cause blobs to be produced from unwanted reflection sources. This value can be set between 0-1 to minimize reflections and obtain clear marker images. The amount of light emitted by Vicon camera strobe units. Whether or not the Vicon camera is currently enabled for use.
