Configuring the VerticalPillars Environment in AntilatencyService

This section describes the VerticalPillars Environment configuration. Like the horizontal Environments, the vertical ones are made up of IR markers, combined in reference bars. Markers can be placed directly on walls, special racks and pillars. During the configuration, we will prepare Environment for practical use: set up markers in the room, create an Environment scheme and transfer the reference bars coordinates for tracking operation.

IR Markers Installation

Let's take a look at the VerticalPillars Environment configuration. It is assumed that the bars are already installed and have a strictly vertical position.

Creating an Environment in AntilatencyService

To create a new Environment, click on the "+" sign in the window lower right corner and select the "New Environment" menu item.
Then specify Environment name and select the "Pillars" type.
After that you need to set up the Environment parameters:
The system supports some different IR marker placements in the reference bar. Thanks to this, unique combinations (features) are formed, which allow the tracker to quickly and accurately determine its position in space.
By default, the first and last IR markers are located at the lowest and highest points of the reference bar. The proportion determines the position of the mid IR marker relative to the first, i.e. relative to the lowest point.
Let's take as an example 1 meter long pillars with three markers. By default, the system offers to use 3 pillar types with different proportions. Set the value proportion 0 = 0.25, proportion 1 = 0.5, proportion 2 = 0.75.

Placing the reference bars in the editor

After defining the parameters, the main editor window will open. It uses the three-dimensional coordinate system (X, Z, Y), as shown in the figure below.
By default, the VerticalPillars Environment already includes 2 reference bars defining the area center. They differ from the rest of the reference bars added by the user. First pair can only be moved synchronously along two axes (X, Y) of the three available (X, Y, Z). This is to maintain the Environment center during editing and optimization.
Next, you need to indicate the approximate location of the remaining reference bars. To do this, use the "+ / Add Pillars" button on the window left side. When you click on the button, it will be underlined with a red line, and the system will offer bars possible types (which were defined by the user during the initial setup).
Place different types reference bars within the Environment (based on their physical placement).
Save draft Environment with the "Save" button located in the window upper right corner. Below, in the Environment Data table, the coordinates and type of each reference bar will be displayed.
For a 3D view hold down the right mouse button and move the cursor. To return to the 2D view, double-click the right mouse button.

Changing the reference bars position in the editor

The reference bars position can be adjusted in two ways:
Column number
X axis coordinate
Y axis coordinate (height above floor level)
Z axis coordinate
Bar type (0 - the first type, 1 - the second type , 2 - the third type)
After reference bars position adjustments, click on the "Apply Data" button.

Optimizing reference bar placement

Next, it is necessary to optimize the scheme so that the bar positions in the editor correspond to the physical positions. To do this, use the constraints tool.
Measure the physical distance between 2 adjacent bars installed in the room. Then select these bars in the editor window (using the mouse area selection or the Shift + left mouse button shortcart). Then press the menu button "Add constraint".
In the window that appears, you must specify the measured distance between the selected reference bars.
An arrow with dimensions will appear between the reference bars, where the upper number is the measured distance between the bars, and the lower number is the distance on the scheme.
If the distance on the scheme is less than the measured distance, then the line and number will be red; if the difference between the distances is within acceptable limits, then the line and number will be green; if the distance between the bars is greater than the measured one, then the color is blue.
Repeat the procedure for the remaining pairs of reference bars. The more measurements are the better, but it needs not less than three for each bar. After adding all the constraints, press the "Optimize" button to automatically correct the position.
The scheme now corresponds to the physical bars arrangement. The VerticalPillars Environment is configured.
