LiDAR scanner is a remote sensing instrument that uses pulsed laser light to measure distances and create highly accurate 3D models of environments or objects.The main purpose of LiDAR is to obtain precise, three-dimensional spatial information about the shape and surface characteristics of the environment.This detailed 3D data enables a vast range of applications across many industries, including:Autonomous Vehicles (Self-Driving Cars): LiDAR provides real-time, high-resolution 3D maps for obstacle detection, avoidance, and navigation. Surveying and Mapping: Creating highly accurate Digital Elevation Models (DEMs) and topographic maps of large areas from airborne or drone platforms.Construction and Architecture: Generating detailed ''as-built'' documentation of structures for renovation, progress tracking, and ensuring alignment with design plans (like BIM).Forestry and Environmental Science: Measuring vegetation height, canopy density, and tracking changes in land cover or erosion patterns. Archaeology: Uncovering hidden or subtle ancient structures beneath dense vegetation.Robotics: Giving robots and drones the ability to accurately sense their surroundings for navigation and interaction.
