Portable Iris Drugs Detector With High Efficiency Results
Ⅰ The Introduction of Iris Toxicology Scan
The iris drugs detector uses AI automatic learning training
algorithm to detect whether a person uses drugs or not by the
changes of iris (pigment, texture) and pupil (pupil enlargement and
reduction values based on spectral mapping principle). After a
large number of repeated training and correction of data, the
recognition accuracy was improved, and the innovation of iris drugs
detection algorithm was first achieved.
The instrument detector can quickly and accurately determine
whether a person takes drugs through the detection and analysis of
the iris sample. It is easy to carry and operate. Put the detector
on the tested person’s eyes to collect and identify the iris, and
analyzes whether the tested person takes drugs through the built-in
iris AI drugs detection algorithm. The detection can be completed
within 10s, with high efficiency and accurate results, which can be
widely used in the screening of various anti drug sites.
Ⅱ Technical Principles of Iris Toxicology Scan
The structure of human eye consists of sclera, iris and pupil. The
sclera is the white part around the eyeball, accounting for about
30% of the total area; The center of the eye is the pupil,
accounting for about 5%; The iris is located between the sclera and
the pupil and contains the richest texture information, accounting
for 65%. Through spectral mapping, the pupil constriction occurs
when the pupilary sphincter in the iris contracts; When the light
becomes weak, the dilator muscle of iris contracts, and the pupil
becomes larger.
After encountering light stimulation, the physiological
characteristics curve of the eyes of a long-term drug user is
inconsistent with that of a normal people. As the intensity of
light changes, the changes of drug users’ pupil and iris, and the
specific presentation of iris texture also differ from that of
normal people. According to the comprehensive physiological
characteristics of the eyes, the detector calculates the
physiological curve to analyze whether there is drug use.
Ⅲ Core Functions of Iris Toxicology Scan
1.One click quick screening
Detect 99% of the drugs on the market, including traditional drugs,
new drugs and mixed drugs.
The operation is simple, one person can complete it alone, and the
whole process of detection only takes 10s.
2. Verification of face and ID card consistency
Built in second-generation ID card reader and face acquisition
module, which can verify the consistency of face and ID card at any
time .
3.Print test results
Support GPS positioning, and automatically lock the address during
detection .
Support the printing of test results. The Bluetooth connected
portable printer can print test results anytime and anywhere .
Ⅳ Product Advantages of Iris Toxicology Scan
1.Quick preliminary screening
People of any gender, age and nationality can be accurately
detected, and wearing contact lenses does not affect the accuracy
of the detection. It can be used for mass detection of a large
number of people in public places and entertainment places, and the
recognition result of each person can be completed within 15
seconds from the collection.
2. Complementary to the traditional methods
The detector can be used to quickly screen a small number of
suspicious persons from a large number of people, and then use the
traditional test method for secondary confirmation, which forms
complementary advantages with the traditional tests, such as urine
test, blood test, saliva test, and hair test.
Advantages compared to urine test, saliva test, and hair test
Project Method | Iris Drugs Detector | Saliva Test | Urine Test | Hair Test |
Sample Size | Non | Less Small | More Large | More Large |
Intrusive sampling or not | Non-intrusive | Non-intrusive ( Hard to adapt physically) | Non-intrusive (Privacy Violation) | Non-intrusive |
Whether the sample is infectious | No | Yes | Yes | No |
Sampling efficiency | Very fast and easy | Fast and easy | Slow, labor consuming and easily mixed with, or replaced by fake
samples | Very slow, professional sampling required |
Detection time(Including sampling time) | 10s(Sampling 5s) | mins | mins | mins |
Whether there is cross-reactivity of the detected substances | No | Yes | Yes | No |
Whether chronic drug use can be detected | Both ongoing and chronic drug use can be detected | Only ongoing drug use can be detected | Only ongoing drug use can be detected | Both ongoing and chronic drug use can be detected |
Whether it can be used for on-site screening | Yes | Yes | No | No |
Whether there are secondary discards causing pollution | No | Yes | Yes | Yes |
Sample preservation | Easy | Hard | Hard | Hard |
3.Strong identity authentication
At the same time of rapid screening, the detector can obtain the
information of face, iris and ID card to carry out online
verification of face and certificate consistency through multiple
public security systems, and identify the identity information of
personnel accurately in multiple dimensions to avoid illegal and
criminal acts such as one person with multiple certificates and one
certificate with multiple certificates.
4. Deep learning
The detection and screening system is integrated with the latest
in-depth learning technology, embedded with an efficient in-depth
neural network framework to continuously improve the identification
accuracy. The data is synchronized for training and verification,
and the algorithm is optimized based on the data training results.
5. Safety and environmental protection
The use of pupil detection avoids contact with the saliva and urine
of the tested person. The testers do not have to worry about
infection from COVID-19, AIDS or STDs, and no contaminants are
produced during the detection process.
6. Prospective
The detection and screening system is relatively independent from
other public security systems. It can provide standard interfaces
for other public security systems to meet the flexible access of
various business systems.
