Now most engineering, industrial units or process use the 3 dimensional scanning services (or 3D Scanning) for obtaining various kinds of data through other ways and means. 3D laser scanning services has only recently made its entry in the technical, engineering, industrial and other spheres of modern technology. Today most customers requires that the data obtained through 3D scan be post processed for obtaining better results, though most are pleased with the typical data obtained.

 

For the scanning process you can find no set rules because of its use, because the info obtained by this process greatly benefits us and can also be useful in many cases. The key characteristics of 3D laser scanning services are as follows: Obtaining high definition 3D surface information of any physical part or object. These laser scanners can effectively and accurately capture the parts of varied shapes, sizes and the material within a fraction of the time. This results in detailed inspection productivity and accuracy of the process.

 

Additionally with the use of 3D laser scanning it is possible to obtain an incredible number of points across the whole geometrical figure of the scanned object, thus making it easy for the investigator to accurately describe the free form surfaces as well digitalize it completely. The top information that's obtained is employed for making part to CAD inspection and for reverse engineering the CAD models from the initial physical objects.

 

Obtaining a complete digital type of the test specimen enables us to ensure almost any feature or surface inspection can be done whenever required and never having to redo the measurement.

 

Additionally laser scanning is performed through entirely non contact process compared to the traditional touch probes process which was earlier used. Potential scratches to the fragile components or pressing of flexible parts are avoided through the laser scanning process, whereas in the sooner process there is always the likelihood of the same.

 

Whilst in use, the 3D laser scanners beam an extensive laser stripe on top of the object or part that is usually to be scanned. An inbuilt camera captures the projected laser stripe and then converts it into 1000s of 3 D measurement points by the usage of triangulation and digital imaging methods. The scanner is attached to a localizer which enables to ascertain the particular position of the scanner in the 3D space. The accurate 3 D coordinate points of the scanned surface is decided by combining the scanner measurements that's been obtained with the scanner position that comes out of the localizer. Localizers vary from articulated arms to the traditional coordinate measuring machines (also referred to as the CMMs) and also to the latest industrial robots which can be being used today.

A propos de l'auteur

With the evolution of the digital capability of the scanners that's recently been introduced, the scanned surfaces are displayed on a screen on realtime basis and dynamically adapt sensor performance are used based on the varying surface material, color and its reflection. Today 3d laser scanning services and solutions can be found in different measurement volumes, accuracy classes and also in handheld models, CMM models and robotic configurations as well to match the operator's needs.
