At the forefront of this transformation is the DJI Matrice 4E—a state-of-the-art drone designed to redefine how professionals approach 3D modelling, aerial surveying, and conservation mapping.
Whether you’re preserving a centuries-old gatehouse, capturing data over large landscapes, or creating digital twins for architectural design, the DJI Matrice 4E offers unparalleled versatility and innovation.
DJI Matrice 4E: Transforming Conservation and 3D Modelling
Drones have become indispensable in conservation and surveying projects. The DJI Matrice 4E, equipped with cutting-edge features, offers a tailored solution for industries requiring pinpoint accuracy and high-quality visuals.
Heritage Site Surveys Made Simple
For professionals working to preserve historic structures, accurate data is non-negotiable. The DJI Matrice 4E is built to handle the intricate details of small models (like a gatehouse relic) while scaling up to survey large areas efficiently. With its mechanical shutter and five-directional oblique capture, the Matrice 4E captures multiple angles in a single flight—making it easier to model heritage sites with millimeter-level precision.
Versatility for Any Task
While perfect for capturing delicate architectural details, the Matrice 4E is equally effective for large-scale ortho mapping. Whether you're creating detailed 3D assets for a site or analyzing broader landscapes, this drone adapts effortlessly to your needs.
Innovative Features That Redefine Efficiency
The DJI Matrice 4E's innovative features are a game-changer for professionals in 3D modelling, aerial surveying, and conservation mapping. Here’s what sets it apart from its competitors:
- Smart 3D Capture Mode
This feature simplifies 3D model creation by automating precise mapping routes based on a rough model of your target. It improves efficiency by 40% compared to traditional 3-directional oblique capture.
- 5-Directional Oblique Capture
The gimbal intelligently rotates to shoot from multiple angles, enhancing data quality and reducing the need for additional flights.
- Dedicated Surveying Payload
A 4/3 CMOS 20MP sensor with a mechanical shutter enables rapid 0.5-second interval shooting, providing unmatched survey speed and accuracy.
- Low-Light Optimization
Night Scene Mode and superior obstacle avoidance features make low-light shooting safe and effective.
- Enhanced Precision
With in-camera distortion correction and integration with DJI Terra software, you can achieve reconstruction accuracy with less than two pixels of residual distortion.
These features make the Matrice 4E the go-to solution for professionals demanding efficiency, precision, and quality.
Simplifying 3D Modelling with Smart 3D Capture
One standout feature of the DJI Matrice 4E is its Smart 3D Capture Mode, streamlining the creation of highly detailed 3D models.
Step-by-Step Workflow
1. Rough Model GenerationStart by flying the drone over the target area. Oblique captures generate a rough 3D point cloud model in DJI Pilot 2 software.
2. Flight Route Planning
Define your survey area, and the drone generates an automated flight plan with adjustable parameters like speed and shooting distance.
3. Route Execution
Execute the route with the 5-directional oblique capture to gather detailed data in fewer flights.
4. Survey Quality Review
Evaluate the captured data using a detailed quality report, ensuring the model meets your standards.
The Smart 3D capture function is a powerful new tool to simplify and automate the process of generating robust 3D digitisation. This feature allows pilots to complete detailed measurements and model irregular-shaped buildings.
