DJI Matrice 4E

DJI Matrice 4E is a professional-grade drone that excels in both hardware configuration and intelligent functions, making it a benchmark product in the fields of professional surveying, mapping, and inspection. The following is a detailed evaluation of the DJI Matrice 4E:

I. Excellent Hardware Configuration

●Camera System: The Matrice 4E is equipped with wide-angle, medium-telephoto, and telephoto cameras, as well as a laser ranging module, to meet the needs of various scenarios. Particularly noteworthy is its 112x hybrid zoom camera system, which can clearly identify license plates from a distance of 250 meters. This feature is especially useful for tasks such as power line inspections.

●Image Transmission System: It comes with the O4 industry-grade image transmission system, which combines an 8-antenna system and adaptive selection technology, along with a high-gain receiving antenna built into the remote control. This allows for a transmission distance of over 25 kilometers, ensuring stable and clear image transmission.

II. Powerful Intelligent Functions

●AI Target Detection: The Matrice 4E has built-in models for detecting people, vehicles, and boats, and supports third-party model extensions. It also offers up to 10T of onboard computing power, supporting ultra-clear matrix detection. The image transmission screen can simultaneously detect up to 128 targets, and up to 1000 targets can be detected in photos. This function plays a crucial role in scenarios such as rescue and inspection.

●Autonomous Route Planning: Equipped with a high-precision positioning system, the Matrice 4E can autonomously plan routes and execute tasks, greatly reducing the operational burden on the pilot. When paired with the "GS2" remote management platform, it also enables real-time monitoring and cloud-based data management, improving work efficiency.

●Laser Annotation and Measurement: The laser ranging module enables real-time precise annotation and measurement. Simple operations such as pointing, drawing lines, and drawing shapes can be used to complete tasks such as marking search and rescue target locations and calculating the length of a wildfire's front line. This function represents a revolutionary change in the field of surveying and mapping.

●Close-up Photography and Detailed Mapping: The Matrice 4E supports close-up photography and can create a rough model on the remote control side. Based on this rough model, it can quickly generate detailed mapping routes that closely follow the surface of the subject being photographed. It also supports displaying virtual space routes and waypoint photos for close-up photography, facilitating the assessment of flight safety and coverage areas for detailed routes.

III. Wide Range of Applications

The Matrice 4E is not only suitable for scenarios such as power line inspections and building inspections but also plays an important role in fields such as rescue and environmental monitoring. Its excellent hardware configuration and intelligent functions significantly improve work efficiency in these application scenarios.

IV. Price and Cost-effectiveness

The starting price of the Matrice 4E is 27,888 yuan. Although the price is relatively high, considering the efficiency improvements and safety guarantees it brings, it still offers high cost-effectiveness for professional users.

V. Potential for Improvement

Despite its excellent hardware configuration and intelligent functions, the Matrice 4E still has some room for improvement. For example, in some complex professional scenarios, operators still need to possess certain professional knowledge and skills. For long-term continuous operation scenarios, frequent battery changes may be required to maintain operational efficiency.

In summary, the DJI Matrice 4E is a standout professional-grade drone, excelling in hardware configuration, intelligent functions, and application scenarios. Although its price is relatively high and there is some room for improvement, it generally offers high cost-effectiveness and market competitiveness.
