Context
This article will introduce the definition, ways of generating and use in the built world of a point cloud. A point cloud is a digital representation in 3D of a physical object or space, composed of numerous individual measurement points, each defined by coordinates in x, y, and z axes. Depending on the capturing method and sensors used, these points may also include RGB colour data or intensity information, reflecting the laser pulse’s strength that generated each point.
Evidence
Pending intelligence enrichment.

(btw.media) Also read: 3 key impacts of cloud computing on security operations (btw.media) There are two primary tools you can use to capture a point cloud: laser scanners and photogrammetry. A laser scanner is a survey-grade system that includes a number of different sensors and technologies. A laser scanner is a high-precision system incorporating various sensors and technologies , with a lidar sensor being central. This sensor uses rapid laser pulses to collect hundreds of thousands of highly accurate measurements per second. Additionally, most laser scanners feature an RGB camera to add colour to the point cloud and an inertial measurement unit (IMU), akin to the accelerometer found in smartphones but designed for professional-grade use.
