3D Annotation
What is 3D Annotation?
3D annotation is the process of labeling and tagging three-dimensional data to facilitate the training and development of machine learning models, particularly in applications involving computer vision, robotics, and augmented reality. This specialized form of annotation involves identifying and marking objects, features, and spatial relationships within 3D models or point clouds. By providing precise annotations, such as bounding boxes, key points, and semantic labels, 3D annotation enables AI systems to understand and interpret complex spatial environments. These annotations are crucial in various industries, including autonomous vehicles, gaming, medical imaging, and industrial automation, where accurate 3D modeling and analysis are essential for effective decision-making.How we deliver 3D point cloud services

Types of 3D point cloud annotation services
3D Bounding Box Annotation
3D bounding boxes are drawn around objects in a 3D space, capturing their height, width, and depth. This type of annotation is used to define the spatial boundaries of objects within a 3D environment.
3D Point Cloud Annotation
Point cloud annotation involves labeling data points within a 3D point cloud, which represents the external surface of objects in three-dimensional space. This type of annotation is used to classify and segment different objects or regions within the point cloud.
3D Semantic Segmentation
Similar to 2D semantic segmentation, 3D semantic segmentation involves labeling each point or voxel (a point in 3D space) within a 3D model according to the object or class it belongs to. This provides a detailed understanding of the scene by categorizing every part of the 3D space.
3D Object Tracking
3D object tracking involves identifying and following the movement of objects through a 3D space over time. This type of annotation tracks the object’s position, orientation, and trajectory within the 3D environment.
3D Keypoint Annotation
In 3D keypoint annotation, specific keypoints on an object are marked in a 3D space. These keypoints could be joints, facial landmarks, or other significant points on an object or human figure.
3D Polygon Annotation
3D polygon annotation involves outlining the precise shape of objects in 3D space using polygons. This method captures the exact contours and surface areas of objects, providing a high level of detail.
3D LiDAR Annotation
LiDAR annotation involves labeling and classifying objects within LiDAR-generated 3D point clouds. This type of annotation is critical for interpreting LiDAR data, which is often used in autonomous vehicles and geographic information systems (GIS).
3D Mesh Annotation
3D mesh annotation involves labeling and segmenting the surfaces of a 3D mesh model. A mesh is made up of vertices, edges, and faces, which are annotated to define the structure and classification of objects within the 3D model.
3D Volume Annotation
3D volume annotation is used to label and segment volumetric data, such as medical scans (CT, MRI). This involves annotating specific regions within the 3D volume, such as organs or tissues, to assist in diagnosis or research.
3D Instance Segmentation
3D instance segmentation is similar to semantic segmentation but focuses on distinguishing between different instances of the same object class in a 3D space. Each instance is labeled separately, even if they belong to the same category.
3D Lane and Road Marking Annotation
This type of annotation involves labeling lanes, road markings, and other relevant features within a 3D space. It’s specifically used for training autonomous vehicles to navigate roads safely.
