surfaceCONTROL sensors are used for 3D measurements and surface inspections. The sensors use the fringe projection principle to detect diffuse reflecting surface and to generate a 3D point cloud. This point cloud is subsequently evaluated in order to recognize geometry, extremely small defects and discontinuities on the surface. Sensors with different measurement areas are available. This enables the inspection of the finest of structures on components as well as shape deviations on large-area attachments. Powerful software packages are available for evaluation and parameter setting.

surfaceCONTROL DefMap3D for individual surface analysis (Not included in standard scope of delivery) surfaceCONTROL DefMap3D is a comprehensive software solution for the detection and analysis of surface defects. It includes all components and processes required for set up, configuration and evaluation of inspection tasks. The wide range of features equally supports the analysis of individual parts, the measurement of small series as well as the robot-supported inspection of several measuring fields. Sensor control, calculation of the 3D point cloud and defect detection can be automated using macro commands. As part of the surface analysis, the software provides several methods of detecting and objectively evaluating shape errors within the surface data. The targeted use of different filter types can reduce the effects of surface structures (e.g. graining). A report containing the inspection results is generated. surfaceCONTROL DefMap3D is available in different versions whose scope of performance is oriented towards different measurement tasks. Digital shape The 3D data of the surface is described using polynomials. Depending on their degree, the polynomials have the ability to adapt the shape of the surface like an envelope. The 3D data is compared against the calculated envelope and possible deviations in the surface are identified as defects. Digital stone With the 3D data, you can determine the two highest points (point of support) along a line segment in a given direction. Afterwards the gaps between this line and the 3D data are calculated. Digital light tunnel The captured 3D data is given defined properties (color, gloss) and optionally reflected on the screen with a diffuse light or a light bar. This is how even the smallest defects become visible and can be assessed visually. |

| Industrial Surface Inspection |
Requirements High quality finished surfaces are a challenge for many areas of industry. As well as in the automotive industry, these challenges are present in domestic appliances, entertainment devices and living accessories. The perceived quality of smooth, defect-free surfaces is determined by the feel of the surface, the color and a uniform surface appearance. Even the smallest of defects that are visible under special lighting conditions can disturb the overall impression. As well as the visual demands, there are technical needs too, which require an immaculate surface. One example is the evenness of faces, which guarantees a save fit across the entire surface of the components. When inspecting the surfaces, there are two primary challenges:
Bumps - Dents - Pimples - Drag marks - Waves - Pockmarks - Neckings - Edge detection - Impact lines - Cracks - Contraction - Distortion - Evenness - Shape - Completeness |

| Technology |
The surfaceCONTROL product line was designed specifically for the inspection of diffusely reflecting surfaces, e.g. metallic surfaces (uncoated, electroplated, EPD), plastic surfaces and ceramics. The sensor based on the fringe projection principle scans the surface and generates a 3D point cloud of this surface. Therefore a sequence of structured light pattern is projected on the surface. The calibrated cameras use this pattern for searching corresponding points, from which the 3D data is calculated. Sensors with different measurement areas and resolutions are available. The surfaceCONTROL Inspection Tools software offers recognition of the smallest defects and errors on the surface. There are different options to find and evaluate the deviations in the 3Dpoint cloud, from which the optimal process is chosen according to the corresponding inspection tasks. The calculation of the 3D data and the data analysis is made with an industrial PC. Advantages of the INB systems

| Measuring Principle | The surfaceCONTROL 3D 3500 works according to the principle of optical triangulation based on fringe projection. Using a matrix projector, a sequence of patterns is projected onto the test object surface. The light of the patterns diffusely reflected by the test object surface is recorded by two cameras. The three-dimensional surface of the test object is then calculated from the recorded image sequence and the knowledge of the arrangement of the two cameras to each other. | The surfaceCONTROL 3D 3500 works according to the principle of optical triangulation based on fringe projection.

| Evaluation Process |
Digital Master In the first step, the parts are chosen, which are accepted as OK by the customer. The surfaces of these components are captured with the surfaceCONTROL 3D sensor. The parameters of acceptable surface forms are calculated via the generated 3D-data and archived in an associative memory. Behind this is a neuronal network, which is trained with the data. In the inspection process the surface data of the object to be inspected is first captured with the sensor. Afterwards the software reconstructs the object based on the trained data and calculates an individual master. Then it is compared against this master. When there are no differences between the calculated master and the part that is controlled, the part is flawless. Deviations are shown in a DefectMap. This process is ideally suited to series control. Digital shape The 3D data of the surface is described by a set of mathematical functions using two dimensional polynomial approximation. Depending on their degree, the polynomials have the ability to adapt the shape of the surface like an envelope. The 3D data is compared against the calculated envelope and possible deviations in the surface are identified as defects. The digital shape evaluation is suited for fast analysis of flat and slightly curved surfaces. Digital stone The digital stone is used on the previously captured 3D data directly. During this process the software is looking for the two highest points (point of support) along a line segment. Afterwards the gaps between the line segment and the 3D-data are calculated. It is mainly used in the analysis of defects in the toolmaking process as well as in pre-production series. Digital light tunnel It can be very difficult to detect very small local deviations on tested components, in particular on matt surfaces. It is common practice, for example, to paint vehicle body parts in glossy black and inspect under special lighting, such as a light pipe, in order to get a visual impression of a defect's geometric form. This process cannot be used for all surfaces, it requires additional time and material, and the components cannot be used afterwards. This is why surfaceCONTROL offers the possibility to impose defined characteristics (color, glossy finish) onto the captured 3D surfaces and inspect them on the monitor either under diffuse lighting or with a light bar. So without any additional material even the smallest defects become visible and can be assessed visually. |

Inspection of car body components One of the main application fields of surface inspection system is the identification and analysis of deformations and discontinuity in automotive body shell parts. In modern stamping lines, automotive body shell parts are produced in a cycle time of a few seconds. The processes which have to be controlled are very complex and require lots of experience. Because of the different fouling, material tolerances or variations in the process, unwanted shape defects such as pimples, bumps, dents and neckings may appear. A visual recognition of these defects on metallic surfaces is almost impossible. For production release and after defined time intervals (0.5 - 1 h) such components are chosen, whose surface is completely checked by physically feeling or pulling with a stone. This process is highly complex and contains the risk of not recognizing failures. With every step in the manufacturing process the value of the components and the effort involved in reconditioning increases. In-process detection and retraction of the failures helps to minimize quality costs. With the surfaceCONTROL product line INB has developed a system that scans the surface of the car body components with a 3D sensor in a few seconds and offers the detection and evaluation of local defects. A digital stone, for example, is used for the analysis. This block is moved over the 3D-data of the surface like a physical block. The length and direction of the block is adjusted according to the shape of the surface. The result is the DefectMap; a graphical representation of the defect with exact information about the height and depth. The determined values can be used for an automatic OK/NOK-decision. All body shell parts made of metal are inspected; beginning with the pressing machine to the assembly line, the body in white to the EPD coating. The sensor can be mounted to a robot for the inspection of body components. Inspection of exterior plastic parts In recent years, the use of plastics has increased in vehicle design, as is the case with the outer skin. Examples:
These systems recognize relevant deviations from 5 ... 50 µm (depending on the surface) typically within a few seconds (0.5 ... 2.0 s), and evaluate them objectively. Even the slide marks of the bolt with a height of about 1µm can be recognized. The surfaceCONTROL inspection systems can be used in different stages:
The overall impression of a vehicle's quality is strongly influenced by its interior. This is why high quality materials, tight manufacturing tolerances and the perfect assembly of interior components are critical. One key aspect is the control panel and dashboard, which can always be seen by the front seat passengers. As well as the visual requirements, functional and security requirements also have to be fulfilled. For this reason, the passenger airbag has a predetermined breaking line which is generated using a laser. This "weak point" ensures the safe opening of the airbag at the predetermined breaking line. Due to the heat input when fixing the airbag in place, or because of the mechanical pressure of the control panel, sink marks may appear, which can be recognized under certain light conditions. Furthermore, welded components on the bottom side of the control panel such as the ventilation duct, airbag module, glove compartment etc. may lead to visible undulations on the surface. The surfaceCONTROL systems enable fast, objective evaluations to be made of the characteristics of any shape deviations, both on grained and smooth surfaces. |
