3D Annotation
Elevate your models with precision 3D annotations. Tailored for diverse industries, our service enhances spatial accuracy in AI and computer vision applications.
Defining 3D Annotation
Annotation in three-dimensional data, such as point clouds, incorporates depth, distance, and volume considerations. While cuboids are commonly utilized, alternative methods involve the use of voxels (3D pixels) for semantic segmentation.
Where is 3D Annotation Commonly Applied?
Medical: Analyze 3D scans, including CTs and MRIs, for detailed medical imaging.
Geospatial: Detect 3D structures on Synthetic-Aperture Radar imagery for precise environmental analysis.
Automotive: Track vehicles using LiDAR point cloud data for advanced driver-assistance systems.
Industrial: Identify anomalies on 3D scans of products for quality control in manufacturing.
Agriculture: Enable harvesting robots for fruit picking through annotated 3D data.
Retail: Detect gestures and poses for VR and AR applications, enhancing the shopping experience.
Advantages & Disadvantages
Advantages:
Rich Information from Additional Dimensions:
- 3D annotation provides richer insights by considering additional dimensions, particularly valuable in challenging 2D conditions like fog or darkness.
Adaptability to 2D Data:
- Offers versatility by allowing 3D annotations to be approximated on 2D data, enabling tasks like segmentation of DICOM slices or cuboid estimation based on perspective.
Disadvantages:
Time-Consuming Process:
- 3D annotation is a time-intensive task, requiring advanced tools capable of efficiently handling large volumes of data.
LiDAR Precision Challenges:
- LiDAR data precision diminishes with distance, impacting annotation quality due to point dispersion as objects move away from the source.
