UAV3DCrop

UAV3DCrop is a multi-year UAV crop dataset containing field imagery and associated reconstruction metadata for agricultural research.

Project page: UAV3DCrop

Paper: UAV3DCrop: Benchmarking 3D Reconstruction in Repeated Multi-Angle UAV Crop Surveys

Code: GitHub

Companion depth dataset: UAV3DCrop Depth

Repository Contents

The dataset is organized by year and acquisition day. A scene may include:

• RGB images in an images/ directory;
• camera parameters and image references in transforms.json;
• a sparse point cloud in sparse_pc.ply.

Coordinate Frames

Canonical JSON/PLY coordinate release (2026-08-15)

For all 93 released scenes, the camera translations in transforms.json and the XYZ coordinates in sparse_pc.ply are expressed in the same synchronized metric coordinate frame. Scenes in the same year/crop group share a local origin; coordinate frames from different groups should not be combined without explicit alignment.

• The 2023 JSON and PLY coordinates were converted together from their legacy normalized storage representation using the verified per-scene normalization.
• The 2024 and 2025 JSON and PLY coordinates remain in metre-scale local coordinates.
• Canonical JSON files use identity normalization metadata (scale = 1.0 and avg_pos = "0 0 0"); do not apply a legacy scale or average-position transform again.
• Camera rotations, image references, PLY vertex order, and PLY vertex colors are unchanged by the coordinate-frame update.
• No absolute projected-coordinate shift or geolocation offset is included in the public files.

Files at older repository revisions may use the earlier coordinate representation. Download the current default revision for the canonical paired JSON/PLY release.
