3D Scanning Without Contact
Written by Laser Design   

The process of 3D scanning has an increased number of applications due to astounding advances in technology. Typically, it is used in creating 3D models of items which are then put to use in a variety of ways. It’s also the first step in the process of reverse engineering. Moreover, it has numerous uses in the realms of orthodontics and the medical field.

 

As technology continues to become more advanced, three dimensional scanning will also become more sophisticated in conjunction with the new developments. For instance, it can now be used to scan extremely large objects like bridges or automobiles.
Primarily, 3D scanning is intended to make a point cloud which is a recreation of the surface area of an object. The imagine made by the point cloud relates to the surface are of the item that’s been scanned.

The points on the surface of an object correlate to the points on the point cloud, and the point cloud information is usually used to create NURBS surface models, triangle mesh models or CAD models for a wide array of applications.

Three dimensional scanning can be used in both non-contact and contact measurement. Contact measurement, as the name indicates, means that contact must be made with the item scanned in order to make a replication of its shape. It’s performed by CMM scanners which are typically used in manufacturing procedures.

This scanning method has some drawbacks; for instance, since it comes into contact with the item being scanned, it is not recommended for delicate items. As a result, contact scanning cannot be used in fine art or archeological applications. Non-contact scanning, alternatively, uses lasers to determine the points on the surface area of an item.
Numerous non-contact scanning models are on the market. These kinds of scanners all utilize laser technology to reproduce 3D models of objects. Large bridges and machinery can be scanned with long-range lasers, and objects that have a unique or awkward shape can be scanned with high precision models. Smaller, easy to scan objects can be scanned with portable 3D scanning devices.

If the concept of scanning has piqued your interest but you aren’t ready to commit to purchasing a scanner, you can also rent portable scannesr to use at your convenience. There are scanning procedures available that will give you the results you need regardless of the object you need to scan.
