LiDAR Point Clouds
LiDAR point clouds are three-dimensional datasets generated by Light Detection and Ranging (LiDAR) sensors, consisting of millions of points that represent the surfaces of objects in a scanned environment. Each point contains spatial coordinates (x, y, z) and often additional attributes like intensity, color, or classification. They are widely used for creating high-resolution digital models of terrain, buildings, and other structures.
Developers should learn about LiDAR point clouds when working in fields like geospatial analysis, autonomous vehicles, robotics, or 3D modeling, as they provide precise environmental data for applications such as mapping, obstacle detection, and simulation. Understanding point cloud processing is essential for tasks like data filtering, segmentation, and feature extraction using libraries like PCL or Open3D.
