Preguntas frecuentes

Why are laser scanners so expensive?

Laser scanners are expensive due to their advanced optical systems, high-precision lasers, strict manufacturing tolerances, and angular accuracy. These components are necessary to achieve millimeter-level accuracy and reliable long-range measurements.

What is a point-cloud survey?

A point-cloud survey is the result of a laser scanning process in which millions of points with XYZ coordinates are collected. Each point represents a measured location on an exposed surface, creating an accurate 3D dataset of existing conditions.

What are LiDAR surveys?

LiDAR surveys are point-cloud surveys performed using LiDAR technology with terrestrial, mobile, or aerial laser scanners. They capture exposed surfaces only and are commonly used for buildings, industrial facilities, infrastructure, and large outdoor areas.

How is a point cloud created?

Point clouds can be obtained through laser scanning (LiDAR), photogrammetry, or echo sounders. Laser scanning uses laser pulses, photogrammetry uses overlapping images, and echo sounders use sound waves for underwater or low-visibility environments. All methods require a consistent coordinate system for integration.

How much does a LiDAR survey cost?

LiDAR survey pricing depends on project size, surface complexity, and equipment selection. Terrestrial LiDAR offers higher accuracy, while mobile LiDAR provides faster data collection with slightly reduced precision.

What is a LiDAR scanner and what is it used for?

A LiDAR scanner is a device that emits laser pulses to measure distances and generate point clouds. It is used to capture accurate 3D representations of existing conditions for engineering, design, construction, and asset management purposes.

Does laser scanning damage the eyes?

No. Modern laser scanners use Class 1 lasers in compliance with IEC 60825-1 standards. These lasers operate below the maximum permissible exposure for eyes and skin and are considered safe during normal operation.

How much does laser scanning cost?

The cost of laser scanning depends on the size of the area, the complexity of the environment, and the type of scanner used. Larger areas generally reduce the cost per square feet, while complex spaces increase field time and data processing requirements.

What is a point cloud?

A point cloud is a collection of millions of 3D points defined by XYZ coordinates and additional attributes such as intensity or color. It is used to digitally represent the geometry of real-world objects and environments.

What is the difference between LiDAR and laser scanning?

LiDAR (Light Detection and Ranging) is the technology used to measure distances with laser pulses, while laser scanning is the practical application of that technology. Laser scanners use LiDAR to capture precise 3D data, known as point clouds, that represent the existing conditions of a space or area.

What is a laser scanning service?

A laser scanning service is a professional data-capture process that uses laser scanners to collect accurate 3D measurements of buildings, facilities, terrain, or industrial environments. The result is a digital representation of existing conditions, typically delivered as point clouds and 360-degree panoramic images.

What can be obtained from a laser scanning service?

A laser scanning service produces point clouds and 360° panoramas as primary deliverables. From this data, secondary outputs such as as-built drawings, 3D models, digital twins, and clash detection analyses can be generated using CAD or BIM software.

What is a point cloud used for?

Point clouds are used for as-built documentation, 3D modeling, digital twins, clash detection, volume calculations, measurements, and verification of existing conditions in engineering, construction, and industrial projects.

Why is laser scanning used?

Laser scanning is used to accurately capture existing conditions when precise measurements and full spatial context are required. It provides a complete three-dimensional representation of an environment, reducing uncertainty, rework, and design errors.
