What is LiDAR scanning and how does it work?

LiDAR (Light Detection and Ranging) technology has revolutionised the digitisation of building environments. In this article, we look at what LiDAR scanning is, how it is used in building and the three main types of LiDAR scanners: static, drone and mobile.

Applications of LiDAR scanning in the building industry

LiDAR scanning allows architects, engineers and interior designers to create accurate three-dimensional models of buildings and interior spaces. These digital models are used for a variety of purposes, such as retrofit design, interior planning, analysis of existing structures and interference detection.

Types of LiDAR scanners and their advantages

Static LiDAR scanner: This type of scanner is used when accuracy is crucial, reaching up to 2 mm accuracy. They are placed on a tripod or fixed position and capture data with high resolution and detail, although their scanning time is longer than other systems.
 

Drone LiDAR scanner: Mounted on drones, these scanners offer flexibility and mobility to capture data in outdoor environments. They can fly at different altitudes and angles, covering large areas quickly. They are ideal for digital terrain models, topographic mapping and geospatial surveys, with accuracy down to 5 cm.

Mobile or slam LiDAR scanners: Designed to capture data on the move, these scanners are mounted on vehicles or in the technician’s hand. Equipped with precise positioning technology and motion data capture systems, they are ideal for digital models of roads, linear infrastructure and urban environments.

Advantages of LiDAR scanning in the building industry
Accuracy: LiDAR scanners capture highly accurate three-dimensional data, resulting in detailed and reliable digital models.
Efficiency: LiDAR data capture is faster and more efficient than conventional methods, saving time and resources on building projects.
Full coverage: LiDAR scanning allows full coverage of the environment, capturing minute details and complex shapes of objects and spaces.

LiDAR scanning has transformed digitisation in building. With static, drone and mobile LiDAR scanners, building professionals have powerful tools for accurate and efficient digitisation.
