Description

Technical Field

[0001] The utility model belongs to the technical field of optics and relates to an accurate and portable RGB extraction device based on a smart phone. Background Art

[0002] In the fields of optical detection and image processing, the extraction of RGB color information is crucial for subsequent color analysis, image reconstruction and other processing steps. However, the human eye has different sensitivities to the three color components, and directly using the Euclidean distance to measure the similarity of colors may produce large deviations. Compared with traditional analysis methods of visual observation and complex instruments, smartphones have the advantages of fast analysis speed, portability, and real-time detection, which provide a certain impetus for the extraction of different colors. However, smartphone photography is affected by environmental conditions. Light conditions, shooting angles, and different background colors will affect the detection results. For example, in the environment, as long as the brightness of the light changes, the three color components (R, G, B) will change accordingly, which increases the complexity of color recognition. Therefore, the combination of a light-shielding device and a smartphone not only helps to reduce the impact of the external environment, but also can identify and capture the color changes of the material to be tested through the smartphone and convert them into RGB values. This device that can efficiently and accurately extract RGB color information in the environment is of great significance for improving the efficiency and accuracy of optical detection and image processing.
