How important is the sensors' field of view for effective in-flight detection: The field of view of the DJI Air 3S sensors is one of the most crucial factors for achieving effective in-flight detection, as it defines the area of the environment that the drone can analyze in real time to identify obstacles, calculate distances, and adjust its trajectory. Each sensor is strategically located on the drone's body to cover a specific direction: front, back, sides, above, and below. These angles are calibrated to provide a three-dimensional view of the immediate space and allow the navigation system to anticipate collisions, maintain safe routes, and facilitate the execution of intelligent functions.
If the field of view of one or more sensors is partially covered—whether by dirt, poorly positioned accessories, extreme flight angles, or environmental interference—the drone loses its ability to perceive in that direction. This means it may not detect an obstacle approaching from that angle, increasing the risk of impact, or it may activate unnecessary braking functions due to misinterpreting the information received. The wider and clearer the field of view, the more information the system can gather to make accurate and safe decisions.
In complex flights, such as those in urban or industrial environments with multi-level obstacles, having a full field of view is vital for the APAS system's avoidance algorithms to calculate effective alternative routes. If the drone lacks a clear view to one side, for example, when flying near a facade or inside a hallway, the system may not find a valid escape route and choose to stop or request manual intervention. These types of interruptions not only affect flight efficiency but also increase the likelihood of errors if not acted upon in a timely manner.
For this reason, it is essential for the pilot to keep the sensors free of physical obstructions and avoid mounting accessories that interfere with the field of view of these components. Furthermore, it is advisable to adjust the drone's orientation during flight to always maintain an appropriate viewing angle based on the direction of movement. With a full, operational field of view, the DJI Air 3S can unleash its full autonomous flight potential, leveraging its sensing system to deliver a smooth, safe, and professional experience in any scenario.
