Product Principle
Pupil changes are primarily influenced by the central nervous system. After drug use, the central nervous system is impaired, leading to abnormal pupil responses to light. The pupil detection device applies a light stimulus to the eye (based on the principle of the pupillary light reflex). This stimulus inevitably causes changes in the pupil, which are then analyzed to determine whether the subject is suspected of drug use. Our approach combines pupil feature detection with traditional methods for detecting eyeball lesions (e.g., identifying concave spots, speckles, radial patterns, pigmentation, ciliary features, and other detailed characteristics), significantly enhancing accuracy.
