Automatic Tracking System – UShow V1.0 Release Notes
Ushow is an intelligent automated tracking system developed in combination with UWB positioning technology and advanced algorithms..
Function highlights ：
1. It supports up to 15 light fixtures and 4 tracking targets. The maximum data refresh rate for a single tracking target can reach 100Hz. The maximum distance between the anchor and tracking tag can reach 600 meters. However, this depends on the hardware model, the number of system base stations, and the data communication rate settings. It can be configured according to the customer’s needs.
2. It support 4-8 anchors. If it is an outdoor open area without any obstructions between the anchors and the positioning tags, 4 anchors are sufficient. For projects with potential obstructions, it is recommended to deploy more anchors around the tracking area.
3. The professional algorithm can automatically calibrate the position of the light fixtures. If it is difficult to determine the hanging position of the light fixtures using a laser rangefinder, this feature can be used for quick test positioning. However, there may still be errors due to the limitations of hardware distance measurement capabilities. It is advisable to use a laser rangefinder to determine the coordinates of the light fixtures whenever possible.
4. It supports PSN protocol for outputting the position of tracking tags. It also supports switching between different coordinate systems and depth inversion.
5. It supports remote control of light fixtures via PAD (android or iOS).
6. It also supports camera input for real-time monitoring of the stage situation. It can import floor plan layouts as well.
7. It supports exporting and importing data of light fixtures and anchors.
8. It supports setting the tracking area on the stage, automatically turning on/off the lights when entering/exiting the area. Corresponding trigger signals can be sent via OSC to trigger audio and video playback in other software.
9. It supports switching between height offset and fixed height mode. For fixed height tracking, the corresponding anchor layout needs to be adjusted accordingly if 3D tracking is required.
10. It allows setting the corresponding high and low values for the ZOOM parameter of each light fixture to achieve automatic adjustment of the ZOOM effect.
The hardware of the entire tracking system mainly consists of anchors, tags, and a wireless gateway. The corresponding positioning calculation and processing require the use of a high-performance computer. Additionally, the communication between this system and the computer can be established through either wireless or wired connection. For wireless communication, it can be connected to a wireless router or directly to a wireless hotspot created by the computer’s wireless network card. For wired communication, it can be connected directly to the computer’s network card using an Ethernet cable.
The image above shows the positioning anchor, which can also be used as a positioning tag.

The image above shows a wireless gateway.
The wireless gateway’s USB port can be connected to the A0 anchor using a USB to Android adapter cable. This allows the A0 anchor to send data to the computer. As long as the anchor is connected to the tag, it will automatically send data to a fixed IP address. Therefore, you need to ensure that the IP address of your computer’s network card matches the fixed IP address set in the gateway. The default IP address is 192.168.2.72.
The wireless gateway requires external power supply. You can directly connect it to a mobile power bank through the OTG port (Android port) for power, or use the provided charger for power supply.
The anchor itself has a built-in rechargeable battery. Under regular full charge, it can standby for about 12 hours, and the tag can standby for about 20 hours. However, this may vary depending on the data refresh rate.
Wireless gateway connection methods
System Connection ：
Since the anchors have built-in batteries and can be used with wireless gateways, there is no need to run various signal wires when setting up the anchors. Simply tape the A0 anchor above 1.8 meters from the ground, preferably in a high and unobstructed location. If there are walls, try to keep it at least 0.5 meters away from the wall. Wireless signals are most affected by human obstruction, so try to keep the positioning tags away from the human body as much as possible. Then, connect the anchors to the wireless gateway, which can be connected to the server according to its connection method. Place the rest of the anchors clockwise at the same height to form a rectangular plane. If there are four anchors, try to form a square plane for the best accuracy in algorithms. If a rectangle is formed, the aspect ratio should not exceed 2:1, otherwise, the positioning accuracy along the longer side may be affected.

Software Introduction :
First is the software’s left panel, where all the settings related to the lighting fixtures are located. Each section has an up and down arrow icon on the left side, which can expand or collapse the related parameters. The first section, “Lighting Fixture Settings,” has a right-facing arrow icon on the far right that can hide or show the entire left panel.
All slider adjustment items can be directly adjusted using the mouse scroll wheel, and right-clicking can restore the default values. The yellow parameters are specific to each individual lighting fixture, while the purple parameters are global parameters, such as Footprint-Dimmer.
The lighting fixture settings section contains parameters dedicated to lighting fixture-related settings. The channel mapping section allows for global parameter settings and channel mapping, ensuring consistency with the lighting fixture channel table used for tracking. The DMX settings section enables configuring output using Artnet or sACN. The PSN settings section enables different coordinate system conversions.
On the right side of the software is the upper-right corner showing the software’s running frame rate and a save button.
Below that are the View settings, space settings, anchor settings, and tag settings.
The tag settings section allows you to configure the functionalities for each tag, such as automatic dimmer, and other related settings.
After understanding the general layout of the software’s UI, we can now proceed with the debugging process.
