How does laser triangulation 3D scanning technology improve manufacturing processes?

Laser Triangulation 3D scanning technology relies on a?simple yet ingenious principle using a metrology scanner that takes 3-dimensional measurements of any object by scanning with laser light.

What is Laser Triangulation 3D scanning technology?

The laser triangulation principle functions with the combination of a laser and a camera. A beam of laser is projected onto the surface of the object and using a camera it captures the reflected light.

By knowing the angles and the distance between the laser and the camera, the system calculates the exact coordinates on the object’s surface using a trigonometric relationship.

The term "triangulation" in the context of 3D scanning originates from two main aspects:

1. System Configuration: The components of the system, which include the laser source (1), the camera (2), and the laser line (3) on the object being digitized, are arranged in such a way that they form the three points of a triangle.
2. Mathematical Principle: The method uses principles based on similar triangles. This involves using the relationships and ratios from triangles, with trigonometric calculation, to convert the 2D information captured in the digital image into real-world 3D coordinates.

How does the?laser triangulation principle function with a scanner

1. A laser line is projected vertically onto the object to be digitalised.
2. A camera, inclined at an angle (?) relative to the laser plane, films the scene for the object’s position.
3. The digitised line is transformed into a?series of 2D points with a common abscissa.
4. When the?camera moves, it records and overlaps the laser line being formed to form the entire 3D shape.

Applications of laser triangulation scanning across various manufacturing industries

Laser scanning offers significant benefits across various industries. In manufacturing, it ensures micron-level precision for quality control, detecting defects and verifying complex geometries.

The automotive industry uses laser scanners for part validation and tooling inspection, supporting the development of more reliable and safer vehicles.

Aerospace engineers rely on laser scanning for non-destructive and non-contact testing to capture from intricate details to large assemblies without damaging sensitive components.

Conclusion

Advanced 3D laser scanners like Kreon scanners are built with laser triangulation 3D scanning technology making them incredibly precise and helping industries to be accurate, work faster, and analyse and implement reliable data.
