AI Technical Summary
Existing methods for detecting the color of anti-counterfeiting films are inefficient and have a high risk of missing or wasting materials, making it impossible to achieve real-time and efficient detection.
By employing a combination of a fixed unit, a light source, a calibration plate, and a hyperspectral camera, and controlling the activation of the light source and the state of the calibration plate, the light source spectrum, reflection spectrum, and dark field spectrum are acquired. The reflectivity of the anti-counterfeiting film in each band is calculated. The reflectivity is calculated using the light source spectrum, reflection spectrum, and dark field spectrum, taking into account the influence of ambient light, thus achieving efficient detection of the anti-counterfeiting film.
This improved the accuracy of test results, reduced the risk of waste leakage, and enhanced the production efficiency and product quality control level of anti-counterfeiting film.
