MOBILE LASER SCANNING

Mobile Laser Scanning (MLS) is a surveying technology that involves the use of a mobile platform equipped with LiDAR (Light Detection and Ranging) sensors to collect detailed, high-precision 3D data of the environment.

Mobile Laser Scanning (MLS) is a surveying technology that involves the use of a mobile platform equipped with LiDAR (Light Detection and Ranging) sensors to collect detailed, high-precision 3D data of the environment. The mobile platform can be a vehicle, such as a car, truck, or even a drone, that moves through a survey area while scanning the surroundings.
  • Road Corridor Mapping (CURB, Slopes, Road Edges, Utility Features, Road Markings)
  • Railway Corridor Mapping
  • Topography Mapping
  • 2D Mapping
  • 3D Mapping
  • Planimetric Collection
  • Power-line Catenary Mapping

Key Components of Mobile Laser Scanning:

  1. LiDAR Sensor:

    • The core of mobile laser scanning, LiDAR emits laser beams and measures the time it takes for the light to return after hitting an object. This process creates a dense “point cloud” of data that represents the scanned environment in 3D.

  2. IMU (Inertial Measurement Unit):

    • This sensor tracks the position and orientation of the scanner during the scan, ensuring the accurate georeferencing of the point cloud data to the correct locations.

  3. GPS/GNSS:

    • To ensure the data is geo-referenced and aligned with real-world coordinates, GPS or GNSS systems are integrated into the mobile scanning system. This is crucial for large-scale mapping projects.

  4. Cameras:

    • Cameras may be mounted alongside the LiDAR system for adding color (texture) to the point cloud data, making it more visually informative and improving interpretation.

  5. Software:

    • Specialized software processes the raw LiDAR data and produces a usable 3D model or map of the scanned area. Some examples include Autodesk ReCap, Leica Cyclone, or Trimble RealWorks.

Applications of Mobile Laser Scanning:

  1. Infrastructure and Asset Management:

    • Used for capturing detailed measurements of roads, bridges, utilities, and buildings, making it easier to manage and maintain public infrastructure.

  2. Urban Planning and Design:

    • MLS provides accurate as-built data for architects, engineers, and urban planners, enabling them to design structures and infrastructure projects with precision.

  3. Transportation and Road Surveys:

    • Mobile scanning is ideal for road surveys, providing data on pavement conditions, road signs, traffic barriers, and other features that need to be mapped for transportation planning or safety assessments.

  4. Heritage Preservation:

    • MLS is used for capturing detailed scans of historical buildings, monuments, and archaeological sites, allowing for digital preservation and restoration.

  5. Forestry and Environmental Monitoring:

    • It can be used to map and monitor vegetation, topography, and landforms in forestry and environmental studies.

  6. Construction and Mining:

    • MLS provides real-time 3D models of construction sites or mines, helping track progress, monitor safety, and improve workflow efficiency.

  7. Flood Modeling and Disaster Management:

    • The technology is also used in flood mapping and disaster relief by creating accurate topographic models for assessing risk zones.

Advantages of Mobile Laser Scanning:

  • High Efficiency: Can cover large areas quickly compared to traditional surveying methods.
  • Accuracy: Offers highly precise, 3D data capture, which is ideal for projects requiring detailed measurements.
  • Non-invasive: Data can be collected without having to disturb the site or block traffic.
  • Flexibility: Can be used in a variety of environments, including urban areas, forests, construction sites, or even remote locations.
  • Real-time Data: Allows for immediate processing of data, which speeds up decision-making.
