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 information obtained through 3D scan be post processed for obtaining better results, though the majority are pleased with the overall data obtained.
For the scanning process there are no set rules for its use, because the information obtained by this method greatly benefits us and is also useful in most cases. The main characteristics of 3D laser scanning services are as follows: Obtaining high res 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 in just a fraction of the time. This results in detailed inspection productivity and accuracy of the process.
Additionally with the usage of 3D laser scanning it is possible to acquire an incredible number of points across the entire geometrical figure of the scanned object, thus which makes it easy for the investigator to accurately describe the free form surfaces as well digitalize it completely. The surface information that is obtained is useful for making part to CAD inspection and for reverse engineering the CAD models from the first physical objects.
Obtaining a full digital style of the test specimen enables us to ensure any type of feature or surface inspection can be done whenever required without having to redo the measurement.
Additionally laser scanning is completed through entirely non contact process compared to the traditional touch probes process that has been 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.
While in use, the 3D laser scanners beam a wide laser stripe at first glance of the thing or part that is usually to be scanned. An inbuilt camera captures the projected laser stripe and then converts it into thousands of 3 D measurement points by the use of triangulation and digital imaging methods. The scanner is installed on a localizer which enables to ascertain the actual 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 right out of the localizer. Localizers range from articulated arms to the standard coordinate measuring machines (also referred to as the CMMs) and and also to the newest industrial robots that are in use today.
With the evolution of the digital convenience of the scanners that's been recently introduced, the scanned surfaces are displayed on a screen on realtime basis and dynamically adapt sensor performance are employed on the basis of the varying surface material, color and its reflection. Today 3D laser scanning services and solutions are available in different measurement volumes, accuracy classes and also in handheld models, CMM models and robotic configurations as well to suit the operator's needs.
