Optical 3D measurement and sensor technology#

All-around 3D shape measurement of transparent objects with thermal fringe projection

In many industrial manufacturing processes, there is a need to measure on optically »uncooperative« surfaces. These transparent, reflective or jet-black surfaces are difficult or impossible to detect with conventional sensor technology. A novel 3D measurement technique, awarded as »inVISION Top Innovation 2021«, offers a solution to these limitations. Surfaces are detected via the radiated heat and not via the reflected light. With the »Glass360Dgree« system, Fraunhofer IOF demonstrates for the first time the automatic fast all-around 3D shape measurement of uncooperative objects without surface treatment.

Interactive, robot-guided 3D sensor technology for rapid inspection of large and complex workpieces

In order to automatically scan large and complex shaped workpieces, such as car body or cast parts, sensors are integrated into robot arms during the inspection processes. Each automated measuring sequence must be specifically planned for each workpiece. This teach-in is complex and time-consuming and can therefore only be carried out for a few workpieces. For this reason, a robot-guided sensor system was developed at Fraunhofer IOF that can be interactively controlled by simple gestures of the operator. The gestures are recognized by a 3D interaction sensor and automatically translated into commands for the collaborative robot system. Without having any specialized knowledge, the operator can thus instruct measurement tasks in real time. This new type of human-robot interaction allows human skills and sensor technology to complement each other in quality assurance processes.

Monocular 3D cameras

Fraunhofer IOF has developed a novel camera system for passive, optical 3D object detection. The acquisition principle is based on the integration of a micro-optical phase element within a conventional camera lens. The imaging properties of the lens are modified so that the 3D information of the object field is directly encoded in the captured raw image distribution. Adapted image post-processing can then be used to reconstruct the depth profile of the object on the one hand and the high-resolution lateral object distribution on the other. Possible applications range from human-machine interaction and quality control in manufacturing processes to the field of virtual and augmented reality.

Non-destructive testing with optical coherence tomography#

High-resolution optical coherence tomography for the measurement of thin films

The Fraunhofer IPT, Aachen, is engaged in the development of product-accompanying measurement production-related metrology technology for the automotive industry, mechanical and plant engineering companies, the aerospace industry, medical technology and biotechnology. A large number of industrial applications require high-resolution, non-destructive measurement technology in order to record coating thicknesses in real time and thus regulate the dosage or application quantity during the process. For such applications, which include the measurement of coating layer thickness on a substrate, the Fraunhofer IPT has developed an ultra- high-resolution optical coherence tomography system (ultra high resolution OCT, UHR-OCT), which generates non-destructive cross-sectional images and allows the differentiation of layers in the range of one micrometer.

Non-destructive testing with heat flow thermography#

Automated inspection of forged parts for surface defects with eddy-current excited thermography and machine learning

Despite continuous improvements in manufacturing processes, defects can occur in manufactured forged components, either due to defects in the raw material or deviations from the ideal process parameters. Widely used methods of non-destructive testing are magnetic particle crack detection or dye penetrant testing. With the robot-assisted eddy-current thermography system »ForgeCheckTherm« developed at Fraunhofer IZFP, increased testing reliability can be achieved, among other advantages.

Acoustic monitoring for quality assurance#

IDMT-ISAAC Software for AI-based Acoustic Quality Assurance

Fraunhofer IDMT develops intelligent acoustic monitoring applications based on the latest AI technologies for use in industrial quality assurance. Acoustic methods can provide reliable results where, for example, optical methods reach their limits. At the virtual Control Fraunhofer IDMT presents the latest developments of the prototypical software IDMT-ISAAC for AI-based, acoustic quality assurance - also for users without AI expert knowledge.

Tracking and tracing of objects#

Image based anomaly detection with artificial intelligence

Manufacturing companies face the challenge of further raising this quality standard in order to be able to compete on the global market. To ensure functional and aesthetic properties of a product, Fraunhofer IPK is developing novel approaches for data-reduced AI applications. Thus, it is possible to integrate the advantage of AI-based image processing into the inspection process without having to accept the resulting large effort of training data collection. This is possible by reformulating the inspection task: instead of explicitly detecting learned defects in images, any deviation (anomaly) from a defined quality standard is detected (anomaly). For this purpose, the AI is trained only with defect-free products, which naturally exist in significantly larger numbers than defective products.

Logic. Making AI-based image processing usable

With the Logic. project, Fraunhofer IPK is pursuing the goal of supporting companies in the use of AI technologies. Logic. is based on a modular, service-based platform for solving problems in the field of industrial image processing based on artificial intelligence and offers interfaces to acquisition devices. The assistance system provides suggestions and can thus optimize the industrial process together with the users.

Mobile and marker-free tracing of components (Track & Trace Fingerprint mobile)

Anyone who wants to trace production data back to an individual component or check the authenticity of a component must be able to identify it unambiguously. With »Track & Trace«, the Fraunhofer Institute for Physical Measurement Techniques IPM in Freiburg has developed a system for tracing mass-produced components that recognizes workpieces without any additional markings - solely on the basis of the individual component surface, which provides an almost unique »fingerprint« for each component. The system has now been expanded to include the »Track & Trace Fingerprint mobile« variant. With this portable reading system, users can thus check the condition and history of components throughout the production hall, for example.

Inline optical spectroscopy#

SmartSpectrometer - Intelligent Process Analytics for Industry 4.0

The modular and intelligent spectrometer system »SmartSpectrometer« developed by Fraunhofer IOSB enables the monitoring of quality-relevant material parameters in real-time. Individual solutions for quality and process control can be implemented easily and cost-effectively using various modules. The evaluation of the spectroscopic measurement data is performed by embedded AI (artificial intelligence) at the sensor level so that calibrated quality and material parameters can be transferred directly to programmable logic controllers. Areas of application can be found in the food industry, agriculture or the chemical and pharmaceutical industries. This technology can also be used in the recycling of plastics and textiles.

High-speed image processing for quality assurance#

High-speed image processing using Vision-System-on-Chip

Industrial image processing is considered a key technology for the automation of production processes and is therefore an essential prerequisite for developments in the area of Industry 4.0. In order to live up to the continuously rising requirements on machine vision with minimal latency, further innovations are essential. Fraunhofer Institute for Integrated Circuits IIS, Division Engineering of Adaptive Systems EAS is therefore working on software-programmable image sensors (Vision-Systems-on-Chip or VSoC) based on a new type of processing architecture. The system ist implemented at vosla GmH for the quality assurance of light bulbs. At a testing station for the 360° final inspection very small defects on the glass bodies as well as in the paint application can be localized and measured.

5G technology as the basis for quality assurance#

5G Industry Campus Europe: Infrastructure as an enabler for machine learning applications in production

The Aachen campus will be the first location in Europe to be equipped with an area-wide 5G network in order to fully research and demonstrate the new mobile technology in production.

At the 5G-Industry Campus Europe, the project partners are investigating eight different application scenarios - from 5G sensor technology for monitoring and controlling highly complex manufacturing processes to mobile robotics and logistics to production chains spanning multiple locations. The Aachen scientists also want to test the use of modern edge cloud systems for fast processing of data in order to exploit the potential of 5G in networked, adaptive production.

The indoor and outdoor network of the 5G Industry Campus Europe in Aachen covers an outdoor area of about one square kilometer as well as nearly 7000 m2 in the machine halls of the participating partners, representing all fields of production technology. To ensure direct transferability of the research results to real industrial applications, the 5G-Industry Campus Europe network will be built in the industry-relevant frequency range of 3.7 to 3.8 GHz.

For the application scenarios, a flexible sensor-cloud communication structure is being developed in parallel within the framework of Fraunhofer projects, which will significantly increase the potential for the development of complex machine learning applications for quality assurance.

Surface inspection#

Automated view planning for complex surface inspection

Fraunhofer ITWM has developed a robot-based surface inspection system for the complete inspection of industrial components. The focus is on the objective and complete acquisition and evaluation of the surface. The special feature of the system: it has several interfaces for image acquisition, examines the component, and performs the comparison with the CAD model as well as the visualization of this CAD model; furthermore, it contains the algorithms for the automatic calculation of viewpoints. The visualization of the CAD model is successively modified according to the viewpoint of the robot, so that the regions of the part that have already been inspected are visibly marked

Fast, optical 3D measurement of microstructures and defects on plate-sized surfaces

For fast and highly accurate measurements of surfaces, Fraunhofer IPM uses, among other things, the method of digital multi-wave holography, which enables measurements in the sub-micrometer range with very short measurement times. Whereas previous applications were mainly limited to small, matchbox-sized workpieces, a new development is now available that can also be used to measure components with surfaces up to 190 mm x 150 mm in size. One example of this is the quality control of high-current circuit boards for use in wind turbines. With the new holography system, these can be inspected over their entire surface for micrometer-sized defects with just one image and a measurement time of less than one second.

System for 100 percent control of oil application on metal sheets - F-Scanner 1D

Before sheet metal is formed, the exact dosage of the oil quantity is crucial: If too little oil is applied, the metal could crack later, while overcompensation could significantly impair the next processing steps (e.g. joining processes). With the F-Scanner 1D, Fraunhofer IPM is presenting a fluorescence system that can check 100 percent of the oil applied to a sheet during the production cycle. Integrated in an oiling system, a workpiece can be selectively re-oiled in the event of a shortage.

Inspection of specular surfaces with deflectometry

At Fraunhofer IOSB, the deflectometry method is used to inspect flat or slightly curved reflective surfaces. It can be used to examine embossed, polished, painted or glazed surfaces made of plastic, metal, glass and other materials, and the result is information about the position, size and type of aesthetic defects, as well as the shape and waviness of the surface if required. Possible areas of application for the method can be found in metal, plastic and glass processing or surface finishing and coating.

Fast, precise and non-destructive process monitoring with laser speckle photometry

Laser speckle photometry (LSP) developed at Fraunhofer IKTS is a novel method for inline monitoring of industrial processes. Systems based on LSP can analyze surface properties and draw conclusions about geometry, porosity or surface defects. The applications are manifold and range from monitoring industrial processes (additive manufacturing, biotechnology, welding processes, roll-to-roll processes, etc.) to determining material data (such as porosity or density, stress state, roughness or defect density or impurities) for many material classes, including ceramics.

Optical 3D Measurement#

Model-supported digital quality control from batch size 1

In the manufacturing of individualized products with a large number of variants, more flexible and adaptive optical measuring and inspection systems are increasingly needed for inline quality inspection. The Fraunhofer IFF develops such customized and flexible 3D measuring systems for dimensional and form inspection as well as for assembly and completeness inspection. In addition, individual function modules are offered as software libraries, such as geometric evaluation of 3D scan data, simulation of optical sensors to generate synthetic target data or calibration and calibration of optical sensors.

Hyperspectral Image Processing#

Ultra-compact multispectral cameras based on micro-optics

The special requirement for multispectral camera systems is the simultaneous recording of high-resolution spectral and spatial information. Classical solutions are often based on scanning methods with bulky setups. The new multispectral camera from Fraunhofer IOF, which is based on a multi-aperture system approach with a specifically adapted microlens array in combination with an oblique linear variable spectral filter, can overcome these limitations. The system is only 60 x 60 x 28 mm³, yet offers a large field of view of 68° and spatial sampling of 400 x 400 pixels per channel. Potential applications include environmental and agricultural monitoring, industrial production control and sorting, and biomedical imaging.

NDT 4.0 - Digital transformation and its impact on NDT

At Fraunhofer IZFP, the term »NDT 4.0« or »NextGen NDT« is used to address tasks that will be faced by the »NDT of the future« in the age of Industry 4.0. The goal is to further develop NDT 4.0 into intelligent and IIoT-capable NDT sensor systems based on eddy current, ultrasound and 3MA. The focus is on interfaces using OPC-UA as well as modern documentation options by connecting the systems to DICONDE servers, enabling their integration into existing IIoT networks. It is also possible to combine both technologies to solve an inspection task.

Material characterization with 3MA

Components in mechanical, automotive and plant engineering are heat treated and machined in order to adjust the service properties in a desired manner. With the 3MA testing method developed at Fraunhofer IZFP, it is possible above all to characterize the characteristics of the surface layers, which cannot be satisfactorily tested non-destructively using conventional methods. The method can be fully automated and can be integrated into the manufacturing process. Its high inspection speed allows 100 percent inspection in most applications. The method allows rapid and simultaneous evaluation of several relevant quality characteristics of the surface layer (0 mm to 8 mm component depth).

OPC UA-enabled Screening Check

At Fraunhofer IZFP Saarbrücken, OPC UA is used in the context of Industry 4.0 to ensure the reliable collaboration of different test systems and their integration into existing IIoT networks. The OPC UA (Open Platform Communications Unified Architecture) interface standard is a platform-independent, service-oriented structure for data exchange with mainly meta data – such as date, component type, batch, etc. – and a qualitative statement of material characteristics (OK, NOK) being transmitted. A showcase application in this concept is the inspECT-PRO eddy current screening inspection system for the seamless inspection and documentation of mass-produced parts. In addition to its established use for defect inspection and material characterization for materials such as steel, copper or aluminum, eddy current technology is also very well suited for the inspection of materials with weak electrical conductivity, such as carbon fibers (CFRP).

Terahertz layer thickness measurement in industrial environments

At the Fraunhofer ITWM in Kaiserslautern, terahertz measurement systems are developed which can be used, among other things, to measure layer thicknesses in an industrial environment. As the latest version of the terahertz layer thickness measurement system, a robot-assisted variant is now available, i. e., a collaborative robot, or "cobot" for short, is used for simplified integration into the working environment. The Fraunhofer ITWM system is particularly suitable for the thickness measurement of individual layers within a multilayer system, where the coating can be applied to any material. In addition, moist, sticky, and soft coatings and layers on curved surfaces can also be measured.

Solutions for mobile non-destructive terahertz testing  

Fraunhofer ITWM has developed solutions for the mobile use of non-destructive terahertz testing. Since in many cases the sensor is brought to the component and not vice versa, the mobile solutions allow higher flexibility with respect to the location of the measurement. In addition, mobile systems can also be better adapted to the component geometry and are thus flexible with regard to the measurement arrangement. Potential applications can be found in areas such as maintenance, service and repair, especially on fixed, non-transportable objects. Typical materials are plastics, fiber composites or ceramics in industries such as automotive, rail vehicles or pipe manufacturers.

Intelligent quality assurance through AI-supported analysis of acoustic signals

In the context of Industry 4.0, more and more diverse inspection tasks are emerging, generating larger volumes of data that are often not easy to interpret. Artificial intelligence (AI) can assign meaning to these measured values and assess the overall situation. The systems for acoustic diagnosis from Fraunhofer IKTS, Dresden, can detect errors in manufacturing and operating processes. This is because defective components and critical plant and operating processes exhibit special noise patterns that are used for quality assurance.
