Hi
We are currently working on the project using Vive Mars (two base stations are in use).
As you can see in the current picture, the Camera Tracking: Free-D signal is occasionally disconnected and then re-connected.
At this point, the transformation of LED Wall1,2,3 is turned off. How can we solve the problem?
In addition, Camera Calibrator's Lens Calibration was conducted But should we proceed with tracking calibration? May I know the role of tracking calibration?
Thanks!
Hi,
Tracking Calibration calculates the position of the camera's image sensor compared to your tracking device.
If you don't have tracking calibration, the camera in the virtual world will be placed exactly where the tracker is and not where the camera's image sensor is. If using a calibration file with tracking calibration, then the camera's position in the virtual world will match exactly the real-world camera's position.
You can set this offset value manually at some places in Aximmetry if you didn't make a calibration file, it is referred to as Delta Head Transf.

So yes, you should definitely make tracking calibration.
To fix the No Input of Vive Mars, make sure you have the latest Mars firmware. And try to use only one router between Vive Mars and your computer, with your computer having wired connection to the router and not Wi-Fi.
