3D laser scanning is a non-contact technology that captures the shape, geometry, and surface details of objects or environments in three-dimensional space using laser beams. It is a highly accurate and efficient method for creating digital representations of real-world objects or spaces.

 

Laser Scanning 101

Scanning: The laser scanner emits laser beams that sweep across the object or space, capturing millions of points on the surface. These points are measured based on the time it takes for the laser beam to bounce back to the scanner (time-of-flight) or by using phase-shift measurement techniques.

3D Model Generation: As the laser scans the object a point cloud is processed, and a 3D model is generated. The software analyzes the point cloud data to create a surface mesh, which can be further refined to create a solid model representation. The resulting 3D model is a digital replica of the scanned object or environment.

3D laser scanning offers numerous advantages:

  • High Accuracy: Laser scanning provides a high level of accuracy and precision, capturing detailed measurements and surface features with submillimeter or even submillimeter-level accuracy.

  • Efficiency: Laser scanning enables rapid data capture, allowing for the quick creation of detailed 3D models. It eliminates the need for manual measurements or physical contact with the object, reducing time and effort.

  • Non-Destructive: Laser scanning is a non-destructive method, as it does not require physical contact with the object being scanned. This makes it suitable for delicate or sensitive objects, preserving their integrity.

  • Versatility: Laser scanning can be applied to various industries and applications, including architecture, engineering, construction, industrial design, cultural heritage preservation, forensics, and more.

  • Data Preservation: By digitally capturing objects or spaces, laser scanning allows for the preservation and archiving of valuable data. The 3D models can be used for analysis, documentation, visualization, and replication purposes.

Overall, 3D laser scanning is a powerful technology that enables accurate and efficient digital representation of real-world objects and environments, opening up a wide range of applications and possibilities.

 

High precision rotary scanning

Structured light 3D scanning offers several advantages, including high accuracy, fast data acquisition, and the ability to capture detailed surface information. It is particularly useful for scanning complex shapes, objects with intricate textures, and scenes that require rapid data capture. 

Environmental scanning

Time-of-Flight (ToF): ToF structured light scanning uses a camera and a light source that emits short pulses of light. The time it takes for the light to travel to the object and back to the camera is measured, allowing the software to determine the distance and create a 3D representation of the object.

Probe scanning

Probe scanning, also known as touch probing or tactile scanning, is a method of capturing three-dimensional data by physically touching a surface with a probing device. It involves using a mechanical probe, typically mounted on a coordinate measuring machine (CMM) or portable measuring arm, to make contact with the object's surface and collect measurements at specific points.
