ATOS – Industrial 3D Scanning Technology
Optical 3D coordinate measuring machines are replacing tactile measuring systems and gages in many areas of industry. They capture more detailed and easily interpretable quality information of an object with significantly shorter measuring times.
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 3D Scanner
ATOS Triple Scan
The industrial optical 3D measuring system captures up to two times 16 million measuring points per scan and is used as a high-end scanning and inspection system for shape and dimension analysis in quality control.
ATOS Capsule
The optical precision measuring machine is designed for full-field digitizing of contoured part geometries. The 3D scanner is used for production quality assurance of small to medium-sized parts and excels by its high precision for fine details.
ATOS Core
The optical 3D scanner provides 3D coordinate measuring data for inspection and adaptive manufacturing. ATOS Core serves as a mobile measuring device and stationary desktop scanner. In addition, it supports automation processes within the ATOS ScanBox.
ATOS Compact Scan
Due to it’s scalable measuring areas, the ATOS compact class offers maximum flexibility: by quickly changing the lenses, the mobile 3D coordinate measuring machine can capture components up to several meters in size.
Optical 3D Measuring Technology in Industrial Quality Control
ATOS systems return full-field data about deviations between the actual 3D coordinates and the CAD data. As this measuring data contains all the object information, in addition to the surface deviations from the CAD, the software also automatically derives detailed information such as GD&T, trimming or hole positions.
The accuracy of optical measuring systems is based on state-of-the-art optoelectronics, precise image processing and mathematic algorithms, ensured by stable precision standards and an automated calibration procedure.
ATOS Technology
Triple Scan Principle
Precise fringe patterns are projected onto the surface of the object and are captured by two cameras based on the stereo camera principle. As the beam paths of both cameras and the projector are known in advance due to calibration, 3D coordinate points from three different ray intersections can be calculated. This triple scan principle offers advantages for measuring reflective surfaces and objects with indentations. The result is complete measuring data without holes or erratic points.
Dynamic Referencing
ATOS’ proven stereo camera technique delivers, for each measurement, an over determined system of equations.
The combination of the stereo camera technology with GOM’s reference point system allows ATOS to guarantee process reliability by:
- Detection of sensor/part movement
- Verification of measurement accuracy and quality
- Identification of environmental changes
- Online tracking of 3D sensor position
Blue Light Technology
GOM’s projection technology works with narrow-band blue light, which means that interfering ambient light can be filtered out during image acquisition. The light sources are so powerful that measuring data is captured even on non-cooperative surfaces. In addition, the LEDs of the Blue Light Technology have a life expectancy of far more than 10,000 hours.
Self-monitoring systems
ATOS sensors are self-monitoring systems. The sensors identify changing ambient conditions during operation. The software of the sensors is continuously monitoring the calibration status, the transformation accuracy, environmental changes and part movements to ensure high-quality measuring data.
Live Tracking
In addition to the full-field scanning, ATOS systems can also be employed for live measuring of movements and deviations. This tracking is based on the stereo camera principle in connection with the GOM reference point system. Single points as well as complete components geometries can be traced in space. The alignment or positional deviation of a component from the nominal position can and also be measured and tracked live by the ATOS. This makes it easier to transfer the virtual alignment of components into reality.
Optically Tracked Touch Probe
The GOM Touch Probe combines full-field and touch probe 3D measurement. The GOM Touch Probe allows quick measurement in difficult to access areas, comparison directly to CAD, measurement of primitives, quick measurement of individual points and online alignment.
ATOS and Touch Probe measurements are carried out with one system and are evaluated with one software package. No extra hardware or tracker is required, enabling quick measurement procedures and easy interchange between surface and single point measurement and analysis.
