Make sure to download the MasterControl, with calibration interface.
Now that you have the different components of the VR Tracker system, let’s see how to calibrate the system!
We are going to see step by step how to get a good calibration for the system, and see some problems that you may encounter during the calibration.
1. Turn on your system
The first step is to turn on your system, seems pretty easy right? We suggest that you first turn on the Gateway (you can open the master interface to know when the software is on). You can now turn on a Tag, its color should turn blue, meaning that it is connected to the Gateway. Then turn on the cameras, you will see them appear on the calibration tool, and to be sure that they are working, take the tag and pass it in the area that you want to cover, reorient your camera if needed. When a camera sees a tag you should see a red light from it. Make sure that the different cameras cover the area that you want.
2.Choose the cameras that you want to calibrate
On the calibration tool, you should be able to see a list of cameras that are connected to the Gateway, you can select them by clicking on the respective line. When you click on a line, the corresponding camera should flash green, so you can recognize which one you have selected.
3.The calibration Tag
By now you should have one tag on, it is recommended to only have one tag on at this stage, this will make the calibration easier for you. Once you have selected all the cameras that you want to calibrate, click on the “Validate camera selection”. You should now see the selected cameras with a blue light, and your calibration tag in purple.
4.Enter the calibration points
Now you have to enter the points that will be used for the calibration. All points used should be set in meters. Each cameras has to see at least 4 calibration points, so make sure that you enter enough calibration points. You have two options to enter the calibration points, you can enter them one by one or you can use the text area to enter multiple points and save them for a future calibrations.
Make sure that each point you are using for the calibration is seen by at least one camera.
Once you have entered all the points, click on the button “Enter Calibration View”.
5.Calibrate the system
We are now in the calibration view, you should see something like this :
It indicates the next calibration point where you have to place the calibration Tag, and give you information on how the calibration is going.
For each calibration point you can use 3 options :
-Click on the calibrate button
-Use the Space Bar
-Click on the side button of the Tag (For the first version of the system, the button may not be that easy to use)
6.The different information
When the calibration point is successfully seen by at least one camera, you should see a screen like this:
You should be able to see how many cameras have seen this point.
An error that you might encounter is :
This means that none of your cameras have seen the calibration point
When you have pass through all the calibration points, you should see the message “System calibrated”, and the position of each camera should be displayed below in green if calibrated and in red if not.
