Outline

MaizeField3D is a 3D point cloud dataset of maize plants, designed to address the lack of large-scale and diverse data for AI-based 3D phenotyping research. High-quality 3D point clouds of 1,045 field-grown maize plants were collected using a terrestrial laser scanner (TLS), and 520 of them were individually segmented and annotated into leaves and stems using a graph-based segmentation method. The labeled data are used for procedural modeling to provide a structural parameter representation of maize plants, with leaves represented as NURBS surfaces. The dataset contains metadata on plant morphology and quality, as well as subsampled point cloud data at various resolutions (100k, 50k, and 10k points), and has undergone rigorous manual quality control. MaizeField3D can be used as a foundation dataset for AI-based phenotyping, plant structure analysis, and 3D applications in agricultural research.

Takeaways, Limitations

Takeaways:
Providing a large-scale, high-quality dataset for AI-based corn 3D phenotyping research
Accurately capture structural details of corn plants, such as leaves and stems
Provides data in various resolutions, enabling use in various calculation tasks
Providing structural parameter representation through procedural modeling
Improved data reliability through strict quality control
Limitations:
The dataset size may be limited (1,045 objects)
The diversity of data collection environments may be limited (specific regions, growing conditions)
There is a possibility of bias towards certain breeds.
Possible errors due to limitations of graph-based segmentation methods
