Punktipilvi

Punktipilvi, or point cloud, is a collection of data points in a three-dimensional coordinate system. Each point typically represents a location on the surface of an object or environment. Punktipilvi are generated by various technologies, most commonly 3D scanners, lidar, and photogrammetry. These data sets can contain millions or even billions of points, providing a highly detailed representation of physical space.

The individual points in a punktipilvi often have associated attributes, such as color (RGB values), intensity, or normal vectors. These attributes enhance the information contained within the point cloud, allowing for richer analysis and visualization. For example, color information can make a punktipilvi more visually intuitive and aid in object recognition.

Punktipilvi find applications across numerous fields. In architecture, engineering, and construction (AEC), they are used for site surveying, as-built documentation, and progress monitoring. In manufacturing, punktipilvi can assist with quality control and reverse engineering. The gaming and entertainment industries utilize them for creating realistic virtual environments and assets. Furthermore, in fields like archaeology and cultural heritage preservation, punktipilvi help in documenting and analyzing historical sites and artifacts. Autonomous systems, such as self-driving cars, rely on punktipilvi from lidar sensors for environmental perception and navigation. The processing and analysis of punktipilvi often involve specialized software for filtering, meshing, segmentation, and feature extraction.
