3D Scanning

What?

Use in

How?

A process to collect data of a physical object on its shape and possibly its appearance.

The collected data can then be used to construct digital three-dimensional models (CAD model).

Data is in the form of [Point-Cloud.] uploaded image3D Point Cloud Editor

Challenge when converting Point-cloud to "Mesh" format.

The raw mesh data is not very good. All mesh files must be fine tweaked to get a high quality output.

Holes in the mesh must be filled in.

Manual cleaning of the Mesh give a better result.

Computer Aided Inspection

Replicating parts that have no CAD data

Documenting Museum Pieces

Creating digital data of engineering mockups such as clay or wood

Creating 3D data files of the human face or figure

Medical Device fitting

Laser Triangulation Scanning

Create a 3D image through the triangulation mechanism

Link Title uploaded image
Principle of a laser triangulation sensor. Two object positions are shown.

The laser probe projects a line of laser light onto the surface while 2 sensor cameras continuously record the changing distance and shape of the laser line in three dimensions (XYZ) as it sweeps along the object.
