DJI Terra Overview
DJI Terra is a 3D modeling software tailored specifically for DJI Enterprise drones. Created by DJI, this platform seamlessly integrates with DJI’s hardware, offering a streamlined solution for data collection, processing, and application.
The software’s standout feature is its close alignment with DJI’s ecosystem. It supports enterprise drone models like the Matrice 4E and Matrice 400, along with payloads such as the Zenmuse P1 camera and Zenmuse L2 LiDAR sensor. This integration reduces the compatibility headaches often found when mixing hardware and software from different vendors.
Main Features and Functions
DJI Terra excels in advanced reconstruction techniques, including 3D Gaussian Splatting. This method significantly improves how complex elements - like fine details, transparent surfaces, reflective objects, or vegetation - are represented compared to traditional photogrammetry methods using visible light.
The software is designed for efficiency, processing up to 500 photos per hour for smaller tasks and scaling up to 2,000 photos per hour for larger projects. It also merges LiDAR and visible-light data to create precise point clouds, 2D maps, and 3D mesh models, achieving centimeter-level accuracy without requiring ground control points.
For large datasets, DJI Terra employs cluster reconstruction technology. For instance, it can handle 6,000 photos with just 1 GB of RAM or process 30,000 photos in just 21 hours using five worker devices. This makes it a robust option for managing extensive mapping projects.
Field operations are simplified with automated mission planning. The software generates waypoints and flight paths based on selected points in a 3D reality model or point cloud, which is especially useful for repeat surveys and monitoring tasks. Additional features include built-in PPK (Post-Processing Kinematic) capabilities for high-precision surveys, support for control and check point calibration, and compatibility with over 8,500 coordinate systems.
In practice, DJI Terra has proven its capabilities. For example, researchers in Central America processed over 700 GB of LiDAR data in a single day to create dense digital terrain and elevation models. The software’s point cloud classification tools allowed them to strip away jungle canopies, focusing on ground data to investigate ancient Maya ruins.
While DJI Terra is optimized for users within the DJI ecosystem, this focus can limit its appeal to those relying on a mix of drone platforms.
