FAQ

Frequently asked questions

What does the DJI Matrice 4 Obstacle Sensing Module do?

The DJI Matrice 4 Obstacle Sensing Module combines rotating LiDAR and millimeter wave radar for obstacle detection. This sensor fusion supports improved positioning in low-light conditions and increases operational safety during operations on power lines and in complex environments such as substations.

Does the module detect thin wires and power lines?

The module detects fine obstacles such as 12 mm wires and thin power lines. This reduces collision risks during line inspections.

Performance may be limited if small branches or wires with a diameter of less than 12 mm are in the flight path, or if the drone is flying vertically near diagonally oriented wires.

What detection range does the Obstacle Sensing Module provide?

The LiDAR unit provides 360° vertical scanning. The radar covers a 90° field of view and operates as millimeter wave radar in five directions.

Which drones are compatible with the DJI Matrice 4 Obstacle Sensing Module?

The module is compatible with the DJI Matrice 4D Series and DJI Matrice 4 Series. To use it with the Matrice 4 Series, the drone must be updated to the latest firmware version.

What should I note during installation and commissioning?

The drone must be switched off before installing or removing the module. During installation, the rear screws must be tightened; hex keys are included for this purpose.

After installation, all devices must be updated to the latest firmware and activated according to the instructions in the app. Before flight, you should check that the Obstacle Sensing Module is functioning properly.

Under what conditions may obstacle detection be limited?

Module performance may be affected by environmental factors such as cloud cover, fog, rain, snow, or dust. The material, position, and shape of the target object may also affect obstacle avoidance and bypassing.

The aircraft cannot actively avoid fast-moving objects such as operating wind turbines, moving tower cranes, or birds in flight. Detection may also be limited if an obstacle is located in the module’s blind spot.

DJI Matrice 4 Obstacle Sensing Module – rotating LiDAR and millimeter wave radar obstacle detection

The DJI Obstacle Sensing Module significantly enhances obstacle detection for the DJI Matrice 4D Series and Matrice 4 Series. It combines a rotating LiDAR sensor with millimeter wave radar, combining LiDAR’s high measurement accuracy with radar’s robustness. The result is comprehensive all-around detection, even in confined and structurally complex environments.

Detection of thin wires down to 12 mm

The module also detects fine obstacles such as 12 mm steel cables and thin power lines at flight speeds of up to 15 m/s. This makes it particularly valuable for inspections of high-voltage lines, masts, and other infrastructure, where cables are among the greatest collision hazards.

Wide field of view and long detection range

The LiDAR sensor covers 360° vertically and 60° horizontally, while the millimeter wave radar covers 90° vertically and horizontally. Obstacles are detected at distances of up to 100 m. The module also improves positioning in low-light conditions.

Designed for outdoor use

In combination with the Matrice 4D Series, the module achieves an IP55 protection rating and is designed for an operating temperature range of -20 to 50 °C. The included reflective stickers enable use with the DJI Dock.

Easy installation

The module is mounted directly on the Matrice 4D Series. An adapter bracket is included for the Matrice 4 Series; the drone must be updated to the latest firmware for this purpose.

Note

Detection performance depends on the environment and the material, shape, and size of obstacles. It may be limited in fog, rain, snow, or when objects are moving quickly.

1. Make sure that the drone is switched off before installing or removing the module.

2. During installation, make sure to tighten the rear screws with the included hex key.

3. After installation, update the firmware of all devices to the latest version and activate the module according to the instructions in the app.

4. Before flight, check that the obstacle sensing module is functioning properly. It is recommended to fly only in environments with a stable GNSS signal and good weather. The performance of the obstacle sensing module may be limited in the following scenarios. Pay particular attention to flight safety:

1) The aircraft is unable to avoid fast-moving objects (e.g. operating wind turbines, moving tower cranes, birds in flight, etc.);

2) Obstacle avoidance and bypassing capabilities may vary depending on environmental factors (cloud cover, fog, rain, snow, dust) and on the material, position, and shape of the target object;

3) The obstacle is located in the blind spot of the obstacle sensing module. For detailed information about the blind spot, refer to the user manual of the obstacle sensing module;

4) Small branches or cables with a diameter of less than 12 mm are located near the flight path, or the drone is flying vertically near diagonally positioned cables;

5) Due to applicable national regulations, the radar may not be operated, or may have limited functionality, in certain countries and regions.

5. The obstacle sensing module contains sensitive components; external impact or drops may cause damage or affect accuracy. Handle it with care and avoid dropping it.

6. When the obstacle sensing module is not in use, attach the protective cover to prevent surface wear.
