Transportation, passenger and freight traffic (road, railway, sea) and logistics:
PSI Technics image processing systems enable the recording and structuring of vast amounts of data that in turn translates into technological, safety-related or economic benefit for customers. For instance, data mining can be used to identify creeping wear at an early stage to schedule preventive maintenance, to prevent downtimes and to increase machine availability.
Our engineers developed the camera-based automated train inspection to enable an automated, condition-based maintenance for trains. The system records roof, side and underbody damages of any train that passes the system, for example, when it enters a depot or drives through a dedicated "inspection tunnel". The recorded data is sent directly to the Inspect software.
Deep Learning algorithms enable a fast and efficient classification of recorded pictures. Using taught-in templates of acceptable/unacceptable parts, a deep learning system automatically recognizes any deviations to ensure that damaged manufacturing parts can be automatically identified and removed from production.
Artificial intelligence (AI) algorithms enable camera systems to learn from samples. Based on large volumes of recorded and analyzed data modern machine learning algorithms help to continuously improve the evaluation of quality-related properties. The obtained data can subsequently be used for further processing and analysis.
PSI Technics uses sophisticated systems and processes to provide customized solutions, for example: We help you find the perfect camera system for your application. Volkswagen uses PSI Technics' image processing system (Inline Control System) with 2D or 3D cameras to monitor the trolley wheels of a Power & Free vehicle assembly line.
The system is used for quality and molding inspections during production. 2D and 3D cameras inspect pressed parts, drawn parts and semi-finished products for the smallest cracks, scratches or coating thickness. The inspection can take place at the supplier end or during production. Camera systems are also used to automatically check for the physical presence of components, such as screws, oil filter caps, etc.
Hyperspectral imaging helps to precisely identify changes in material structure and enable the unmistakable identification of uneven paint layers, coating damages or contaminations. Leather applications or different plastics, such as PVC, PETE, PP and PS, can reliably be inspected with this method. Even seal-tight tests for fats or oils don't represent any challenges.
The quality of coated surfaces can be examined for the smallest scratches and dull spots using deflectometry or photometric stereo.
Wherever conventional image processing systems are unable to provide detailed material analyses, hyperspectral imaging offers an entire range of new possibilities.
Organic substances, particularly water, lipids or proteins, can be easily distinguished using Chemical Color Imaging (CCI). The composition of meat products, for example, can be measured using hyperspectral imaging without touching or destroying meat samples. The same method can be applied to identify unripe, overripe or spoiled food in the food industry.
Foreign substances like plastic, shards of glass, metal or machine oil are easily identified at an early stage to prevent costly product recalls and loss of product reputation. Hyperspectral imaging can be used to examine a wide variety of food packagings, for instance, cheese or cold cut packagings, for air tightness or quality issues, since the smallest packaging leaks or tears can contaminate or spoil the contents.
Hyperspectral imaging is also used to identify the quality, purity, composition and contents of various foods and formulations: Ready-made foods, pizza, cereal, instant meals, seasoning mixes, baked goods, cheese, milk products, sausages and cold cuts/meats, fruits and vegetables, etc.
Pharmaceutical agents that seem almost identical to the human eye can have distinctly different properties. Hyperspectral imaging enables a clear distinction of those agents based on their chemical composition.
Metal and metalworking industries and foundries:
Deflectometry and photometric stereo are two different methods of creating analyzable images of shiny or reflective surfaces for the purpose of evaluating the surface quality of metals during production. The method used depends on the task at hand and the process parameters.
Recycling / waste disposal:
The efficiency and productivity of recycling processes can be increased by automatically sorting or filtering out materials using hyperspectral imaging methods. Plastics can be inspected for purity, among others.
Humidity can have a significant impact on the quality of wood. Hyperspectral imaging is used to measure the moisture content and to increase product quality.
Mining and raw materials industry / commodities industry:
Camera technology has proven especially beneficial for process tasks in demanding work environments. Hyperspectral imaging can also be used in the mining industry and in the production of raw materials to differentiate between and identify the quality of various minerals, salts, quartz, earths, clays, ores and types of rock.
Those industries often rely on outdated technologies, such as x-ray technology. Hyperspectral cameras record over 100 different wavelengths, covering a much broader color spectrum when it comes to evaluating the purity of a wide variety of substances. Clays used in the ceramics industry can, for example, be checked on a conveyor belt or sorter for their humidity content prior to firing to help prevent breakage and save energy and costs.
Consumer goods industry:
The quality and purity of plastics – in granular form and in the form of finished products – can be perfectly evaluated using hyperspectral imaging, which works even for transparent materials.
Deflectometry and photometric stereo are used to reveal the smallest scratches, irregularities and dull spots on shiny metallic or plastic surfaces. Products that are inspected with these methods include kitchen appliances, vacuum cleaners, casings and much more.
