3D Point Cloud
What is 3D Point Cloud Annotation?
3D point cloud annotation is the process of labeling and tagging data collected from three-dimensional point clouds, which are representations of physical objects and environments created through technologies such as LIDAR, laser scanning, or photogrammetry. This specialized annotation involves identifying and marking key features, objects, and spatial relationships within the point cloud to enhance the understanding and interpretation of three-dimensional structures. By providing precise annotations—such as bounding boxes, semantic labels, and key points—3D point cloud annotation supports various applications, including autonomous vehicle navigation, robotics, urban planning, and virtual reality.How we deliver 3d point cloud services

We also perform inter-annotator agreement (IAA) checks to ensure consistency across different annotators, which is essential for maintaining high-quality standards in complex 3D data.
Step 8
Data Preparation and Formatting
Once the annotations have been validated, we prepare the data for integration into your machine learning models. This involves formatting the annotated 3D data according to your specific requirements, such as converting it into compatible formats, organizing it into directories, or labeling it according to your system’s standards. We ensure that the data is clean, well-organized, and ready for immediate use without further processing.
Step 9
Prepare Results for ML Tasks
The finalized annotated 3D point cloud data is now ready to be used in your machine learning tasks. We ensure that the data is structured to maximize its utility in training, testing, and validating your models. This may include organizing the data into training and validation sets, normalizing the annotations, or applying any other preprocessing steps required by your machine learning framework. Our goal is to deliver data that enhances the performance and accuracy of your models, ensuring that it is ready for immediate use in your ML pipeline.
Step 10
Transfer Results to Customer
After thorough validation and preparation, we securely transfer the annotated 3D point cloud data to you. Depending on your preferences and security requirements, this can be done through cloud storage, secure FTP, or direct integration into your systems. We ensure that all files are delivered as agreed and provide any necessary documentation or support to help you integrate the data into your workflows. If needed, we offer post-delivery support to address any issues or questions you might have.

Types of 3d point cloud annotation services
3D Bounding Box Annotation
This type of annotation involves drawing 3D bounding boxes around objects in a point cloud to define their spatial boundaries. Each box captures the height, width, and depth of the object, helping in object detection and classification tasks.
3D Semantic Segmentation
In 3D semantic segmentation, each point in the point cloud is labeled with a class corresponding to the object or surface it represents. This type of annotation is used to classify different parts of the environment or objects within a 3D space.
3D Instance Segmentation
Similar to semantic segmentation, instance segmentation goes further by not only labeling each point but also distinguishing between different instances of the same object class within a point cloud. Each instance is uniquely identified.
3D Object Tracking
3D object tracking involves identifying and following the movement of objects across multiple frames in a sequence of point clouds. This form of annotation tracks the object's position, orientation, and trajectory in 3D space.
3D Keypoint Annotation
3D keypoint annotation involves marking specific points of interest on objects within a point cloud, such as corners, edges, or joints. These keypoints help in understanding the geometry and structure of objects in 3D space.
3D Lane and Road Marking Annotation
This annotation type is specifically used for marking lanes, road boundaries, and other relevant features in point clouds captured by LiDAR or other 3D sensors. It helps autonomous vehicles in navigating roads safely.
3D Plane and Surface Annotation
In this form of annotation, planar surfaces and other geometric shapes within a point cloud are identified and labeled. This can include walls, floors, and other large surfaces within a 3D environment.
3D Volume Annotation
Volume annotation involves labeling volumetric regions within a point cloud. This is particularly useful in applications where understanding the full 3D shape and volume of objects or regions is important.
3D Object Classification
3D object classification involves labeling objects within a point cloud with specific classes. This type of annotation helps in recognizing and categorizing different objects based on their geometric shape and spatial orientation.
3D Environment Mapping
Environment mapping annotation is used to label and map out entire 3D environments within a point cloud, such as indoor spaces, urban areas, or natural landscapes. This helps in creating detailed 3D maps for navigation and simulation.
