A Point Cloud contains a large collection of 3D points (X, Y, Z coordinates) that laser scanners capture from real world surfaces and environment.
Laser scanners use LiDAR (Light Detection and Ranging) technology to generate these points.
A laser scanner:
-
Emits laser pulses toward surfaces.
-
Measures the time the light takes to return (Time of Flight).
-
Computes the exact 3D position of each point.
-
Captures millions or billions of points.
Each point can also include:
-
RGB color
-
Intensity
-
Reflectivity
Together, these points create a 3D digital representation of physical environments.
