Tracker 3.9 new features and functions

Compatibility with Vicon Vantage+ cameras

Tracker 3.9 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. 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).

Previously, to run Vantage cameras at higher frame rates while maintaining their maximum resolution, windowing was used, which reduces the size of the FOV.

Now, in new High Speed mode, you can run your Vantage cameras at higher frames rates while maintaining the FOV. You can change frame rates during capture and you do not need to set up your cameras again when you increase the frame rate, as the FOV is unchanged.

Note that because the higher speeds are achieved through subsampling (removing some pixels from the frames), some reduction in resolution is incurred. For details, see High-speed mode in the Vicon Vantage Reference Guide.

To select high-speed mode:

1. With Tracker in Live mode, set the system frame rate to the speed you want to use in High Speed mode.

   

   A warning may temporarily be displayed, alerting you to the discrepancy between the requested frame rate and the actual system frame rate, until you select high speed mode for all the relevant cameras, as explained next.

2. On the System tab, select one or more cameras.

3. In the Properties pane, go to the Settings section, click the Sensor Mode menu and select High Speed.

   

   In the Camera view pane, notice that the High Speed mode icon is displayed in the bottom left corner of the view.

4. With Allow Windowing selected (the default), windowing (reducing the size of the field of view) is used above the following frame rates:
   • V16: 500 fps
   • V8: 900 fps
   • V5: 1060 fps
   If you don't want to use windowing in addition to High Speed mode, ensure the Advanced properties are displayed and clear the Allow Windowing check box.

   

   After a few moments, the system runs at the new speed.
