ATOS Triple Scan - Industrial Optical 3D Digitizer
ATOS Triple Scan is a high resolution, optical digitizer that delivers rapid and precise three-dimensional measuring data by measuring millions of points per single scan. It is effectively applied for the optimization of design processes, thereby improving industrial production processes.
The ATOS Triple Scan can measure shiny surfaces as well as complex components with deep pockets or fine edges (i.e. airfoils, turbine blades, etc). The Triple Scan functionality reduces the number of individual scans required resulting in faster measurement times with high detailed feature capture for various part sizes, surfaces, finishes, and geometries, regardless of environmental lighting conditions.
ATOS sensors are used in many industries for the inspection of parts such as sheet metals, tools and dies, turbine blades, prototypes and injection molded and pressure die-cast parts.
ATOS TRIPLE SCAN TECHNOLOGY
The ATOS Triple Scan operates as 3 sensors in 1 system. Each high quality optical camera works independently from one another thus capturing accurate 3D scans from the left, right, and both cameras with high resolution feature detail. This advanced functionality maximizes data collection and improves scanning of shiny surfaces. Additionally, it minimizes the number of scans, thus reducing the overall measurement time.
TRIPLE SCAN PRINCIPLE
Together with both cameras, the projection unit operates according to the triple scan principle. During the measurement, precise fringe patterns are projected onto the surface of the object and are recorded by two cameras, based on the stereo camera principle. This automatic principle offers advantages in measuring reflective surfaces or objects with complex indentations.
BLUE LIGHT TECHNOLOGY
The ATOS Triple Scan is also equipped with blue light technology. The narrowband blue light enables precise measurements to be carried out independently of environmental lighting conditions.
In GOM’s automated measuring machines, ATOS sensors can be operated together with the Plus Box. The latter is a photogrammetric add-on sensor which can be directly attached to the ATOS system. This enables fully automated measuring of reference point markers with a deviation of 3 μm to 30 μm. These reference point markers create a 3D volume, into which the detailed individual measurements of the ATOS sensors are transformed automatically. This is how the overall accuracy of the overarching photogrammetric measurement is achieved.
SELF - MONITORING SYSTEM
The sensor recognizes changing ambient conditions during operation and is able to compensate these changes. To do so, the software of the sensor is continuously monitoring the calibration status, the transformation accuracy, environmental changes and part movements to ensure the quality of the measuring data.
VIRTUAL MEASURING ROOM
The virtual measuring room (VMR) is the central control station and measurement planning software for all elements of the ATOS measuring cells. It offers the functional representation of a real measurement environment in a virtual simulation. Due to the VMR, the user can work with the system without the requirement for specific robot programming skills. All robot movements are simulated and checked for safety before being performed in the virtual measuring room.
The ATOS Professional evaluation software provides all necessary tools for a comprehensive analysis of parts and components. Using parametric inspection, all actions and evaluation steps are completely traceable and interlinked. Thus, changes and modifications are possible at any time.
High Resolution 3D Scanner for small to large objects
ATOS uses high resolution measuring cameras with up to 16 megapixel resolution and specially developed optics for precise measurement. The accuracy, resolution, and measuring area can be all modified to suit the application requirements. Measuring volumes range from 38mm to 2m. This flexibility allows measurement of a large part spectrum with the same sensor head, and when used in combination with TRITOP, the ATOS System is capable of scanning parts of over 30m with detailed resolution and high data quality.
ATOS TRIPLE SCAN IN USE
AUTOMATED 3D METROLOTRY
ATOS Triple Scan can be extended with a Plus Box photogrammetry add-on in the ATOS ScanBox models of series 5, 6, 7 and 8.. This allows bigger components or multiple parts to be measured.
MOBILE 3D METROLOGY
Manually, ATOS Triple Scan is used with a studio stand or a desk stand. For the semi-automatic use, a 3-axis motorization kit, including a lift module for the sensor and a Tilt and Swivel Unit for the fixture, is available. Mobile rotation tables enable simple automated measurement of small to medium objects. Furthermore the GOM Touch Probe allows point-based measurement of areas that are difficult to access optically.
