Evoke 1.4 is the fourth point release of the Vicon software that controls Vicon’s Origin system.
It includes new features such as the notification of duplicate objects, the ability to calibrate a single selected camera, and support for the use of High Speed mode for Vicon Vantage cameras, as well as fixing a number of issues.
For a more detailed description of these additions and improvements, see New features in Vicon Evoke 1.4.
Evoke 1.4 includes these new features:
To prevent objects from appearing to be too similar or to reduce the risk, you can either increase the Entrance Threshold of the object if possible, or modify the marker positions.
For more information, see Understand object evaluation.
Calibrate selected camera
You can now calibrate or re-calbrate a single camera, without having spend time re-calibrating the whole system. This enables you to add a new camera to your system, or move a single calibrated camera, and calibrate with a shorter wand wave, saving the time it takes to perform a longer wand wave for all the cameras.
To calibrate a selected camera:
System panel improvements
The System panel has been improved for 1.4, making it more responsive and providing more helpful feedback, especially for large systems.
System and device parameters have been reorganized to make it easier to find the options you need.
System file settings are now available from the System Settings menu, to the right of the top menu bar, next to View Settings.
You can now remove disconnected or selected devices from the system (see Remove selected devices).
Most application configuration files are now stored in JSON format rather than XML. Configuration files created in Evoke 1.3.# or earlier are converted on import into Evoke 1.4.
New device status summary
Device category headers are now always visible, and include a summary of device status and warnings. This makes it easier to view the current status of the system and to identify any issues at a glance.
For Pulsars, this includes battery charge level and number of devices on charge.
High Speed mode for Vicon Vantage cameras
When upgraded to the latest firmware (Firmware 725 and later), Evoke 1.4 enables you to use High Speed mode with 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 don't 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:
Remove selected devices
In Evoke 1.4, a new option enables you to remove selected missing cluster(s) from the list of devices on the System tab.
