In the professional drone field, DJI has always led the industry transformation with technological innovation. To address the pain points of core industrial scenarios such as power inspection, emergency rescue, and public security, it launched the Matrice 4T small intelligent multi-optical flagship drone. As the core model of the Matrice 4 series, it takes "portable, intelligent, efficient, accurate and reliable" as its core positioning, integrating a multi-lens imaging system, powerful flight performance and intelligent operation algorithms. It breaks the limitations of traditional aerial operations, provides an integrated and cost-effective aerial solution for various industries, and redefines the operation standards of professional small drones.

Multi-Optical Fusion Imaging System: Clear Details, All-Day and All-Night Capability

Imaging capability is the core competitiveness of industrial drones. The Matrice 4T is equipped with a full-dimensional multi-optical imaging module, realizing seamless collaboration of visible light, thermal imaging and laser ranging, balancing image quality accuracy and scene adaptability, making every detail clearly distinguishable.

In terms of visible light shooting, the Matrice 4T is equipped with three 48-megapixel effective pixels cameras, covering wide-angle, medium-telephoto and telephoto full focal lengths to meet shooting needs at different distances. The wide-angle camera adopts a 1/1.3-inch CMOS sensor with an f/1.7 large aperture, which greatly increases the light intake compared with the previous generation. Even in low-light environments such as evening and cloudy days, it can capture delicate image details. Its 82° field of view is suitable for large-scale scene shooting, such as large-area forest monitoring and urban panoramic survey; the medium-telephoto camera has an equivalent focal length of 70mm and 3x lossless zoom capability, which can clearly shoot equipment details from a safe distance, such as pins 10 meters away in power inspection and instrument data of substations; the telephoto camera has an equivalent focal length of 168mm, supporting 16x digital zoom and 112x hybrid zoom, and still maintains clarity in long-distance shooting, suitable for long-distance accurate observation and identification.

The upgrade of thermal imaging function is even a core highlight of the Matrice 4T. It is equipped with an uncooled vanadium oxide (VOx) thermal imaging sensor, which defaults to infrared super-resolution mode, and the image resolution can be upgraded to 1280×1024, making temperature details clearly visible; each device undergoes temperature measurement accuracy calibration before leaving the factory, and can real-time correct the measurement results with the help of the body temperature sensor to ensure temperature measurement accuracy. Equipped with the newly added near-infrared fill light hardware, the maximum illumination distance can reach 100 meters, which completely solves the problem of insufficient light for thermal imaging shooting at night, making night inspection and search and rescue operations more efficient. In addition, users can mark and analyze thermal imaging pictures through the DTAT 3.0 infrared thermal analysis tool to quickly locate abnormal temperature points, greatly improving work efficiency.

The addition of the laser ranging module further improves the operation accuracy. The module has a normal incidence range of up to 1800 meters (1Hz), an oblique incidence range (1:5 slant distance) of 600 meters, a blind zone of only 1 meter, and a ranging accuracy of ±(0.2+0.0015D) meters (D is the measurement distance). It can accurately obtain target distance information, provide accurate data support for inspection, surveying and mapping and other scenarios, and avoid operation errors caused by distance judgment errors.

In terms of flight speed, the forward flight speed can reach 21m/s in sport mode, 18m/s in side flight, and 19m/s in backward flight, which is significantly improved compared with the previous generation. It can quickly reach the operation site, especially suitable for time-sensitive tasks such as emergency rescue; it also supports constant speed mode, which allows the drone to fly at a constant speed in the specified direction without continuous stick operation, reducing the operational burden on the pilot.

In terms of environmental adaptability, the Matrice 4T performs excellently. Its maximum take-off altitude can reach 6000 meters, and the maximum working altitude with accessories is 4000 meters, which can adapt to operations in complex terrains such as plateaus and mountains; the wind resistance level reaches 12m/s, which can fly stably in windy environments and calmly cope with wind interference during take-off and landing; the working environment temperature range is -10℃ to 40℃, and it can work normally without solar radiation, taking into account high and low temperature scenarios, and adapting to the operation needs of different regions such as severe cold in the north and extreme heat in the south.

In terms of flight safety, the Matrice 4T is equipped with six high-definition low-light fisheye vision sensors, which greatly improve the positioning and obstacle avoidance capabilities in low-light environments, and can realize automatic obstacle avoidance, intelligent detour and safe return in urban low-light environments. The newly added automatic route obstacle avoidance function can automatically identify obstacles such as iron towers and insulators, dynamically adjust the route, and continue to perform tasks after bypassing the obstacles, effectively reducing the collision risk and ensuring operation safety. At the same time, it is equipped with GPS+Galileo+BeiDou+GLONASS multi-satellite positioning system (GLONASS is supported when the RTK module is turned on), with extremely high hovering accuracy: ±0.1 meters in the vertical direction (when visual positioning/RTK is working normally), ±0.5 meters (when GNSS is working normally); ±0.3 meters in the horizontal direction (when visual positioning is working normally), ±0.5 meters (when GNSS is working normally), ±0.1 meters (when RTK is working normally), ensuring stable flight attitude and non-shaking shooting images.
