What sensors does the DJI Mavic 4 Pro use for obstacle avoidance, and how do they work: The DJI Mavic 4 Pro is equipped with an advanced omnidirectional sensing system that combines multiple visual sensors, infrared sensors, and a forward-facing LiDAR system. This integration allows the drone to detect and avoid obstacles in all directions: forward, backward, above, below, and to the sides. Thanks to this capability, the Mavic 4 Pro is able to plan safer flight paths, significantly reducing the risk of collisions, especially in complex environments such as urban areas or areas with dense vegetation.

Each type of sensor performs a specific function in the drone's navigation system. For example, visual sensors identify changes in the texture and color of the environment to estimate the distance to nearby obstacles, while LiDAR more accurately detects the position of transparent objects or in low-light conditions. The infrared system complements this detection by working effectively on surfaces with low visual contrast, such as white walls or polished surfaces.

The processing algorithm of these sensors works in real time alongside the drone's navigation system, automatically adjusting the flight path if it detects obstacles. This includes deceleration, complete stop, or intelligent detour, depending on the avoidance setting selected in the DJI Fly app. These actions are almost instantaneous, providing the pilot with additional safety, even when flying at high speeds or in new environments.

To take full advantage of this feature, it is recommended to fly in well-lit conditions and keep the detection system settings up to date. Although the system is very robust, DJI emphasizes that it should not replace the pilot's judgment; they should always maintain visual surveillance of the drone and have manual control available for any eventuality. The combination of advanced automation and human supervision is key to a successful and safe flight.
