The following points/questions must be considered if good and solution-oriented lighting is to be designed for a vision system: – Monochrome / color (wavelength) – Diffuse or direct / directional lighting – Angle of incidence – Unpolarized or polarized (linear, circular) – Speed of the application – Size of the illuminated area – Light quantity […]
Most common type of lighting in image processing. Light sources are LEDs. Positive features are an extremely long service life (up to 100,000 h), high mechanical robustness (shock and vibration resistance), wide spectral availability (from UV to IR, white), can be used in many types of lighting, small dimensions, simple electrical controllability, good switching and […]
Light source for image processing systems. Different lighting types and → lighting techniques must be taken into account. Other properties to be considered are: Direction of propagation (diffuse, directional, parallel, telecentric), wavelength / color (UV, VIS, NIR, IR), → illuminance, homogeneity, → polarization, flashed or static. The type of lighting depends on what you want […]
The aim of the various lighting techniques is to achieve the greatest possible contrast of the object features to be detected in order to achieve efficient and reliable results for image processing or image analysis. The interaction of the lighting with the test object and its properties must be taken into account. The roughest subdivision […]
