Three methods and four applications of 3D point cloud annotation


What is a 3D point cloud? 3D point cloud is a method of representing the three-dimensional world with point cloud. It can be imagined as materializing three-dimensional objects and using multiple data points to represent an object. Point cloud data is generally obtained by 3D scanning equipment such as lidar to obtain information of several … Read more

What is best 3D point cloud annotation and what are the annotation methods


The perception algorithm based on 3D point cloud data is the core technology path of some autonomous driving companies, and has created a large-scale demand for 3D point cloud data labeling. So, what is 3D point cloud annotation? What are the methods for 3D point cloud annotation? Let’s introduce it below.

How to label 3D point cloud data, 3D point cloud data labeling method


3D label point cloud data annotation includes: feature extraction, 3D reconstruction and matching, and point cloud model extraction. Feature extraction: It refers to measuring the target surface or internal point cloud, obtaining the target surface or internal data, and comparing it with the original point cloud to determine whether there is similarity between the points. Three-dimensional … Read more
