PointCloud2

PointCloud2 is a data format used in 3D sensing technologies, like LiDAR or 3D cameras, to represent the shape and layout of objects and environments. It captures millions of individual points in three-dimensional space, each with precise coordinates, creating a "point cloud" that visualizes real-world surroundings. This detailed spatial information is essential for applications such as robotics, autonomous vehicles, and mapping, enabling machines to understand and interact with their environment accurately. Essentially, PointCloud2 is a structured way to organize and share complex 3D spatial data for analysis and processing.
