Overview

The TrafficDrone unit is a powerful AI inferencing computer housed in a rugged Pelican case enclosure, designed for real-time traffic analytic intelligence. It connects directly to a UAV ground station to extract insights from aerial video streams on the spot.

Function Description:

The TrafficDrone unit serves as a real-time monitoring drone system, capable of analyzing video streams from unmanned aerial vehicles (UAVs) to provide next-generation traffic analytics. It is designed for versatile deployment in various scenarios, from remote operations to stand-alone configurations with internal or external monitors. The core functionality revolves around processing video input to identify, classify, and track targets, and then filtering these targets based on selected criteria to generate traffic insights. The system runs on a Debian operating system and utilizes the FLOW Insights interface for user interaction and analytics management. It supports both live video input from HDMI/SDI and network RTSP streams, as well as file-based video streaming for familiarization or replay of captured footage.

Usage Features:

Unboxing and Setup:

The unit comes with a TrafficDrone processing unit, a "How To Start" guide, wireless keyboard and mouse, a 15.6" touchscreen with accessories and cables, and a carrying case. Optional accessories include a DJI M210 V2 drone and an Elistair Ligh-T V4 tethering system. Cabling includes power, spare powerCON terminal, Ethernet, HDMI, and SDI video input cables.

Powering On:

The unit is powered via a single 100-230V AC input. The power cord connects using a lockable powerCON terminal: insert, turn clockwise until it clicks, then turn on the main power switch. Ensure the main power switch is off before connecting the power cable.

Video Input:

The TrafficDroneUnit primarily requires a video signal for operation, which can be provided via HDMI, SDI, or a network RTSP stream. FullHD 1080p30 format is recommended for best results. Clean video without overlays is preferred, but affected areas can be omitted using the "Region of interest – image cropping” function in FLOW Insights analytics settings. HDMI and SDI inputs switch automatically based on signal presence.

Video Output:

Three video outputs are available for monitoring: two HDMI ports on the rear panel and one USB-C Thunderbolt cable inside the case.

General Purpose Interfaces:

The unit includes four USB interfaces (2x USB-C, 2x USB-A) for external storage, memory card readers, or other peripherals. A Gigabit Ethernet interface (RJ-45 with etherCON enclosure) provides network connectivity.

Configurations:

The TrafficDrone Unit supports various deployment scenarios:

  1. Remote Operation: The unit remains closed, with only power, video input, and network (wired or wireless) connected. It is controlled remotely by the FLOW Insights application running on a different computer.
  2. Stand-alone with External Monitor: The unit is closed, no network connection is required. An external monitor is connected to one of the HDMI outputs. Control is via wireless keyboard and mouse or touch interface.
  3. Stand-alone with Internal Monitor: The unit is opened, no network connection is required. The internal touchscreen monitor is connected to the internal Thunderbolt port and fixed by a magnetic holder. Control is via wireless keyboard and mouse or touch interface, with a magnetic holder for the keyboard.

Quick Start Guide:

After connecting power and turning on, the unit boots into a Debian operating system. Users log in with flowuser (password useruser) for standard use, or flowadmin (password adminadmin) for system administration. Upon successful login, the FLOW Insights interface starts, automatically connecting to the FLOW Block analytics core.

Touch Screen Operation:

The FLOW environment is optimized for touch screen operation, offering an intuitive user experience. A software keyboard can be evoked by pressing an icon, moved around the screen, and closed when not needed.

Frame Grabber Analytics:

Analytics based on HDMI/SDI video input are accessed by clicking the "Frame grabber" tile in FLOW Insights. The system allows users to observe classified targets, their trajectories, and filter them based on criteria. Video stabilization can be enabled in analytics settings for UAV footage to maintain valid trajectories despite camera instability. Georeferencing can be activated for absolute real-world coordinate system referencing, allowing measurements in physical units.

File Streamer Analytics:

In addition to live video, the TrafficDroneUnit includes a file streamer that processes video files sequentially from the /Data/StreamVid directory. Sample recordings are provided in /Data/TestVid. Custom video files can be transferred via USB or SFTP.

Optional RTSP Stream:

The unit can connect to any RTSP stream available on the network (e.g., from an IP camera). Users add a new analytics source, providing the RTSP stream address (rtsp://user:password@ip:port/path/file) and optional OnVIF source address (user:password@ip). The default frame grabber and file streamer analytics also use RTSP streams internally (rtsp://127.0.0.1:8554/grabber and rtsp://127.0.0.1:8554/file respectively).

Remote Access:

The TrafficDroneUnit can be controlled remotely over a network from any computer with the FLOW Insights application installed. This allows for centralized control of analytics while field teams manage UAV operations. Login credentials for the FLOW Block (default: admin/admin) are required. Multiple user accounts with different roles (Administrator, Analyst, Viewer) can be defined for advanced access control.

Integration:

The TrafficDroneUnit offers multiple integration options to leverage its extracted intelligence: REST API, UDP API, Webhooks, and direct control of GPIO pins.

Camera Framing:

Optimal camera positioning and framing are crucial for AI traffic analytics accuracy. Key considerations include:

  • Camera image center should align with the Region of Interest (ROI) center.
  • Sufficient padding between image borders and ROI.
  • Incidence angle between camera lens axis and ground plane normal ideally 0-45 degrees for maximum accuracy and to avoid reflections/dynamic occlusions.
  • Objects in ROI should be fully visible (at least 70% of object area).
  • Avoid capturing the sky to prevent negative impact from sun.
  • Orient camera perpendicular to or aligned with traffic flow to minimize reflections from vehicle lights in night scenes.

Maintenance Features:

Password Management:

It is recommended to change default passwords for system login (flowuser/useruser and flowadmin/adminadmin) and FLOW Block login (admin/admin) to enhance security, especially in advanced scenarios with multiple user accounts.

Remote Support:

For remote support, the unit needs to be connected to a DataFromSky service VPN. This involves running a terminal command (support.sh), confirming with a password, and ensuring network configuration allows UDP connections to flow.datafromsky.com:31231. The TrafficDroneUnit does not connect to external networks automatically.
