Understanding The Importance of Point Cloud Laser Scanner

Point cloud scanning uses a 3D laser scanner to capture various points to measure an area. You can generate a point cloud at speed with a mobile mapping device, static-based Lidar, or Lidar enabled mobile phones.

Point cloud laser scanner uses LiDAR technology, offer numerous advantages, including:

• Enhanced Visualization: Color laser scans allow for easier visualization of construction materials and structural elements, helping in project planning and management.
• Precision Data Collection: They capture millions of data points, resulting in extremely correct and comprehensive 3D models of the scanned environment.
• Digital Records: The scanned data serves as a digital record for facility management, future modifications, and reference all through the lifecycle of a project.

3D laser scanning is a well-known term in architecture, construction, engineering, industrial and infrastructural projects, cultural heritage preservation, as well as other activities that require accurate 3D visualization of spaces and spatial objects. Using the latest 3D laser scanning technologies, the laser scanner sends beams towards the objects to measure its reflection, making data gathering and creating BIM models correct, fast and competent. The process offers us with a quantifiable 3D model in the form of point cloud, where each point has its precise organizes that allow us to determine the geometry and the type of objects in query quickly.

• Processing and registration of point cloud 

Once the field work is done, people move into the office and transfer the raw data from the scanner onto the computer where the processing and registration is done in special software. The first step is automatic pre-processing, where raw point clouds are filtered and colored, and the meta is searched. All of this is done to set up the scans for further use. The term “registration” stands for connection the recorded point clouds (each individual position) into one unit with the goal of receiving the real image of area in question. Depending on the field work method and the evaluation of operators, certain automatic methods of point cloud registration are applied, and the entire process is hand-searched to avoid eventual errors.

• Field work

During the field work part of the process, operators look at the field of interest with the objective of creating a plan for the scanning procedure. Based on the level of detail necessary, projects are made and the settings in the scanner are defined to complete the job as competently as possible. 3D laser scanners are set on definite positions from which the points of areas / objects are gathered. It is tremendously important to set the scanners on locations that allow a sufficient amount of overlapping points between neighboring positions. This way the processing becomes more winning and the end result is of top quality.
