This topic describes how to configure a tag software-wise. For general information about IR ID tracking and links to other chapters please see the topic ID Tag Tracker.

wd_nodes_input_id-tag-tracker_id-tag-config(Single) ID Tag

The software configuration of the tag involves to set up the number and power of the IR LEDs as well as the brightness of the blue control LED. Further, the blinking mode including the ID can be set up.

The tag can be configured via the onboard Micro-USB interface. Connect the tag via the delivered USB cable (Micro-USB to Standard Type A plug) to your computer running Widget Designer. If you connect it the first time, and the driver cannot be found automatically, use the USB-driver “coousb-driver v6.0.13.0” (or a newer one) to finish the hardware installation of the device.

Now, please open the configuration dialog in Widget Designer:
a) Tools > Connection Manager > section ID Tag Configuration
b) Nodes > Input > Devices > ID Tag Tracker > section ID Tag Settings

wd_nodes_input_id-tag-tracker_id-tag-4-configQuad ID Tag

The software configuration of the tag involves to set up the brightness of the IR LEDs and the brightness of the blue control LED. Further, the blinking mode including the ID for each port can be set up. Note that it is possible to set each port to an individual ID or to share the same ID.

The tag can be configured via the onboard Mini-USB interface. Connect the tag via the delivered USB cable (Mini-USB to Standard Type A plug) to your computer running Widget Designer. If you connect it the first time, and the driver cannot be found automatically, use the USB-driver “coousb-driver v6.0.14.0” (or a newer one) to finish the hardware installation of the device.

Now, please open the configuration dialog in Widget Designer:
Tools > Connection Manager > section ID Tag Configuration

 

Mode

This influences the maximum ID a tag can hold. It is recommend to choose the smallest mode available that covers the number of tags you use.
"4" allows four tags holding the ID 1,2,3 and 4. If you want to use ID 5, you need to choose a higher mode, e.g. 8. The tags transmit their ID with a certain blinking pattern that needs to be seen by cameras. The higher the mode is, the longer this pattern gets. Hence, the more time needs to pass in order to recognize a tag if it (re-)appears in the tracking area.
Please note that it is possible to set up several ID tags with the same ID. This does not mean to increase the mode as long as the ID fits into the range. In the section "3D Tracking Settings" you can set up that "same" IDs should result in one averaged position.

Interval

This influences how fast the above described blinking pattern is transmitted. Per default it is set to 20ms.

The lower the frame rate of the used cameras is, the longer an interval needs to be, the slower a tag is recognized. For a frame rate below of 100-120fps an interval of 40 ms is recommended. That applies for most USB cameras.

The higher the frame rate of the used cameras is, the shorter an interval can be, the faster a tag is recognized. A frame rate of 120fps allows to lower the interval to 20ms; 150fps allows even 10ms. However, a longer interval still works with fast cameras and is more robust. In theory, a 10ms interval also works for 120fps but in practice this is very prone to error, hence an 20ms interval is better.

ID

The "ID" depends on the "Mode" chosen above and means the identification number of the connected tag.

Power

Choose the power source of your tag.

Choose "USB / 3V" if you use the onboard Micro-USB interface with the delivered battery pack or your own 3V power source
Choose "A675 Cell" if you use two onboard hearing cells.

See more information regarding the power options in the previous chapter "Required Hardware".

IR LED

Choose which LEDs should blink. 1 and 2 are the onboard ones. Only the "USB / 3V" power source allows to use all LEDs at the same time.

IR Pulse

Set the minimum and maximum brightness used in the blinking pattern when transmitting the tag's ID. It is recommended to set the minimum to 0. The brighter the maximum is, the higher the tracking distance gets and the more disturbing light is possible. Only the "USB / 3V" power source allows to power the LEDs with 100%.

Blue LED

Set the minimum and maximum brightness used for the blue control LED. If you do not want a blinking LED, set an equal value.
The blue LED serves no other purpose than being able to see at first glance whether a tag is on or off.

Save Config

This stores the above settings to the connected ID tag. Now you can unplug it and power it (later).
The settings in the dialog are not reset, hence you can plug a new tag to the PC, change only the ID and save all settings to it.
