DroneVision-for DJI Tello

DroneVision is a real-time visual tracking and control companion for the DJI / Ryze Tello drone.

Connect your phone to the Tello Wi-Fi network, start the live video stream, select a target on screen, and use on-device TensorFlow-based visual detection and tracking during flight.

Features

• Live Tello video streaming with on-screen HUD
• Tap-to-select target tracking
• Object detection and tracking using an on-device TensorFlow-based machine-learning model
• Pose-based person tracking and following
• Orbit mode for circular movement around a selected target
• Observer mode for tracking a person while rotating around a fixed center point
• Real-time telemetry: battery, connection state, altitude, speed, temperature and FPS
• Manual flight control with dual on-screen joysticks
• Normal and Fast flight modes
• Optional GameSir T1d Bluetooth controller support
• Video recording and screenshots
• Automatic control stop / hover behavior when tracking is lost

Bluetooth controller

When connecting a GameSir T1d controller for the first time, Android will request Bluetooth / Nearby Devices permissions. Allow these permissions to use the external controller. Bluetooth permission is not required when using only the on-screen controls.

Requirements

• DJI / Ryze Tello drone
• Phone connected directly to the Tello Wi-Fi network
• Bluetooth enabled only when using the optional GameSir T1d controller

Important safety information

Tracking quality depends on lighting, distance, target visibility, Wi-Fi signal quality and device performance. Machine-learning-based visual tracking does not replace manual flight supervision. The pilot must continuously monitor the drone and remain ready to take manual control at any time.

⚠️ Fast Mode requires particular caution when tracking is active. In Fast Mode, the drone can move and react significantly faster while automatically following or repositioning around a target. This can increase the risk of collision, loss of control or injury.

Do not use Fast Mode with tracking near people, animals, vehicles, buildings, trees, power lines or other obstacles. Use it only in a large, clear and suitable flying area, and always maintain sufficient safety distance.

The pilot remains fully responsible for maintaining control of the drone and for operating it safely and in accordance with applicable laws, regulations and the manufacturer's instructions.
