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
