Three dimensional Scanning Mechanical Parts with Different Dimensional Sizes
Atra Company’s 3D scanner is an industrial type scanner and can be used for industrial parts with a high level of accuracy.
Specialized Lenses for Parts with Different Dimensions
Also, equipping this scanner with specialized lenses for different dimensions has made it extremely flexible in the variety of scanning areas. Also, along with high-resolution lenses, this device is among the most reliable and capable 3D scanners in the country.
Three dimensional scanning without dimensional limit
Most of the other scanners have a certain range of dimensional sizes for accurate scanning so that for larger or smaller parts of the range, scanning will be with a large error and significant details will be lost. One of the advantages of the Atra Company’s scanner is the availability of specialized lenses and the ability to adjust lenses in different situations on the scanner. This feature allows the operator to scan parts of different sizes with high precision and detail.
Powerful Software (Scan with or without Markers)
The powerful software of this scanner is one of its advantages. The ability to scan with or without markers (Target) is another benefit. However, to achieve higher levels of accuracy, markers can be used.
In this software, the positioning can be done with high precision by Auto Alignment ability and without the intervention of the operator. In some scanners merging different shots must be done by the operator. Therefore this procedure causes a significant error. The software has a special Merge component, which integrates all shots optimally with a unique algorithm to enhance the accuracy and quality of the 3D model.

Providing a high level of details
The Atra Company’s scanner, due to its high resolution, specialized lenses, has the ability to provide details in all kind of parts such as wood, furniture, turbomachinery and accurate industrial components. In this industries, details and sharp lines in the scan file are very important features and should not be deleted or softened. Because softening of the edges will reduce the quality of the final product.
For example, the lack of accuracy for the blade of a pump, a turbine or a compressor, leads to an error that will decrease the efficiency and performance of the part compared with the original one. Also, the camera's resolution and the scanner interface also plays an important role in this procedure.
Portability of the 3D scanner is an essential feature to scan in different environments and different types of parts. Some of the parts are heavy, or due to the sensitivity of the work or the lack of time, cannot be carried, and the scanning procedure must be done in site. The Atra Scanner, due to its portability and its low weight, can be present at the site and in a short time scan the mechanical part. Unlike scanners or Arm type CMMs, the Atra scanner does not have any limitation on the size of a piece or working space, as shown below.

The Atra scanner provides excellent accuracy and quality in 3D models due to the use of innovative algorithms based on structured light. The special calibration method used in this scanner improves the quality of the scan. Also, the combination of the new special techniques used in the projector ensures the accuracy and high quality of the scanner.
The Astra scanner provides excellent accuracy and quality in 3D models due to the use of innovative algorithms based on structured light. The special calibration method used in this scanner improves the quality of the scan. Also, the combination of the new special techniques used in the projector ensures the accuracy and high quality of the scanner.
The total scanning process takes between 5 and 7 seconds for each shot. Each shot contains one million and three hundred thousand coordinate points from the surface of the work piece.

Possibility to connect to a photogrammetry camera
To accurately scan large parts (car body, ship, aircraft, etc.) and reduce error, the scanner must have the following two capabilities:
- The scanner must have the ability to scan large pieces accurately.
- The software must have the ability to support and connect to the photogrammetry cameras.
Scanners for scanning very large parts have the ability to support and connect photogrammetry camera’s data to the software. The Atra Company’s scanner, with both features listed, is capable of scanning large parts as well as small pieces.

Ability to connect to Geomagic Studio software with the least error
To edit point cloud, the operator can import the scanner software output into the Geomagic software space. Due to the type of the used mesh by the scanner software, the output file has less error. So, with the professional editing done in Geomagic Studio, the operator can import the point cloud to the Catia software environment or generate the G-code for the CNC machines.
