WebJul 23, 2024 · K-means Clustering. K-means algorithm is is one of the simplest and popular unsupervised machine learning algorithms, that solve the well-known clustering problem, with no pre-determined labels defined, meaning that we don’t have any target variable as in the case of supervised learning. It is often referred to as Lloyd’s algorithm. WebDec 3, 2024 · 3D point clustering is important for the LiDAR perception system involved applications in tracking, 3D detection, etc. With the development of high-resolution LiDAR, each LiDAR frame perceives richer detail information of the surrounding environment but highly enlarges the point data volume, which brings a challenge for clustering …
