It holds an extremely important position. Traditional fault detection methods are operator-based. 15 This results in low productivity and high error rates. In the textile industry, the difficulties encountered in detecting fabric defects... One issue is the inadequacy of lighting and display systems. One-way lighting, It ignores the effect of light reflecting off the fabric from different angles, and this Therefore, detecting defects that are difficult to distinguish, such as stains, knots, fold marks, etc., is crucial. This makes it more difficult. Furthermore, the fabric color creates additional challenges in fault detection. These problems make the fault detection process time-consuming and inefficient. In known technology, lighting is used to detect defects on the fabric surface. In the invention using this system, light is emitted towards the fabric and a light sensing unit is used. It detects the rays reflected from the fabric. In addition, the system has 25 rays emitting light of different colors. There is at least one second light source. In this system, the light source is at a fixed angle. And detection is done using light coming from only one side of the fabric. To flatten circular knitted fabric, use a cylinder and the flattened fabric. In another invention, which features a cylinder located at the bottom for the winding process, the system The knitted textile fabric is tracked synchronously with a digital camera, while the front and 30 Different sides of the fabric are illuminated using backlight sources. Here too... Again, the light sources are positioned in fixed locations and are only visible on both sides of the fabric. Lighting is provided on this side. In addition, during production, the fabric surface is illuminated. Surface deformations such as wrinkles are not encountered. However, storage and 2 Fabrics can be deformed during the production transfer process. Therefore, The system is unable to help solve these types of problems. Using a known technique, the fabric is imaged using an image acquisition module and a light source. A system has been defined to detect errors on it. The system has multiple fields. The fabric is continuously monitored with a scanning camera and a ring-shaped light source, and 5 This system enables the analysis of light at a single wavelength. The light sources are dynamically distributed to optimize the entire surface of the fabric. It is not set as such. Another invention involves automatically detecting and classifying fabric defects. A system is presented for this. Here, an image of the fabric to be examined is taken, and nerve 10 The defect type and dimensions are determined using a network model. In this system, too, digital The fabric surface is examined by monitoring changes in light using cameras. As can be seen, the known technique used in quality control of materials Different methods and systems related to lighting and display technologies However, the light sources are adjustable in angle and 15 adjustable heights, light frequency according to the color of the material optimization and detection of hard-to-detect defects on the material Systems are needed that make this clear.

Optical-based imaging system (1), adjustable angle and adjustable 20 lighting system including high lights (3) top light (8) and a bottom light (2) by using flexible materials in fabric and fabric structure in a synchronized manner and performs surface inspection of inflexible materials such as packaging and glass (7). While examining the surface of this material (7) with the camera (4), firstly, an adjustable angle and Adjustable height lights (3) and top light (8) are activated, making it flexible and pliable. by positioning the surface of the non-existent material (7) at different angles and heights It illuminates. Adjustable angle and height lights (3) and top light (8) After the sources are switched off, the lower light (2) comes on. It enables illumination of the bottom surface of the material (7) and detection of defects. First, the edge detection of flexible and inflexible materials (7) is determined by precise measurement. With the system (9), the width is determined in millimeters. This precise width measurement determines the edge. The system (9) accurately detects the edges of the material (7), thus identifying the materials (7) allows for precise determination of its position. Then the material (7), 4 defects such as wrinkles and folds on the material surface conditioner (5) It is corrected and then enters the viewing area. In order to make the defects on the material (7) more apparent adjustable angle and adjustable height lights (3) at different angles and different It is positioned at heights. The light is adjusted according to the color of the material being controlled (7). By changing the frequency, the lights with adjustable angle and adjustable height (3) and above light (8) sources to the saturation point at which the material (7) can be examined most clearly It is made possible to reach. Adjustable angle and adjustable height lights (3) and The frequencies of the top light (8) sources vary depending on the color of the material (7). The surface of the material (7) has adjustable angle and adjustable height lights (3) and 10 Viewing with camera (4) using top light (8) sources, a fixed light source a more homogeneous image than the surface image of a material examined with (7) It offers the feature that if the light hits the material (7) only at a right angle and from a fixed position. If present, surface defects that are difficult to distinguish, such as stains, knots, fold marks, etc., are usually noticeable. It cannot be done. The fact that the light angles and heights are adjustable makes the material (7) 15 light reflections and shadows on the small irregularities on it This creates a situation where errors become apparent, or what isn't actually an error becomes apparent. It allows the visualization of surface irregularities that might appear as defects. It recognizes the adjustable light angles, the material's (7) various surfaces. By better illuminating their characteristics, it facilitates the detection of errors. Furthermore, 20 The width and position of the material (7) by the precise edge detection system (9) It is constantly monitored and reported on an instant basis. Material surface regulator (5) to correct defects such as folding and wrinkling in a flexible material It is used. Material surface regulator (5), folding in flexible materials, It plays a critical role in correcting defects such as deformation.
