Drug addict pupil detector with high-precision detection rate

Abstract

The invention provides a drug addict pupil detector with high-precision detection rate. The pupil detector includes a detection device housing, a camera lens cone and a stimulating lens cone. The camera lens cone includes an eye lens, a camera and a control circuit, wherein the camera is installed on the tail portion, and the control circuit is connected with the camera. A weak light emitting device is installed behind the eye lens in the camera lens cone and connected with the control circuit. A light emitting device with a weak light source is installed on the rear portion of the eye lens, weak light appears in a dark detection environment, the instinct of the human eyes is to look at what can be seen, the weak light emitting device makes the eyeballs not move in the dark environment, the steady state of watching is kept, and it is thus ensured that the pupil detection process can be smoothly performed. Weak light does not interfere collection of the pupil characteristics, the special brightness and wavelength of the weak light can not stimulate the mood of a person to be detected and makes the person keep quiet and peaceful, the collection of pupil characteristics is facilitated, and finally the accuracy and reliability of the detection are improved.

Description

technical field [0001] The invention relates to the technology of realizing detection results by means of technical means in the field of medical science, specifically a pupil detector for drug addicts with high detection rate. Background technique [0002] The rapid detection technology of pupil dynamic changes of drug addicts is now mature. The common one is the pupil detection device of drug addicts. After testing and recording the dynamic properties of the pupil in a dark light environment, turn on the light stimulation and record the dynamic change of the pupil within 1 minute, so that it can be judged whether the person under test is a drug addict through record comparison. [0003] However, the current defect of this product is that the detection accuracy is not satisfactory. The reason is that there is a problem with the detection accuracy of the pupil of the tested person, mainly because the tested person's glasses are wrapped in the eyepiece The front is carried o...

Problems solved by technology

[0003] However, the current defect of this product is that the detection accuracy is not satisfactory. The reason is that there is a problem with the detection accuracy of the pupil of the tested person, mainly because the tested person's glasses are wrapped in the eyepiece The front is carried out in a dark and dark environment, and because the human eye cannot focus in a dark environment, the eyeballs of the person under test will move left and right, or move up and down during the detection process, which will have a negative impact on the pupil information collection. Even if the eyeballs of the person being tested remain still, they may be in a squinted state, which will still interfere with the test results, resulting in test failure or inaccurate test results
