Problems solved by technology

[0003] 1) The operation of ensuring the accuracy of the sample during urine extraction is also relatively cumbersome, requiring special equipment, locations and specially trained technicians to operate, and the operator is concerned about the possible HIV infection of urine and other issues. Reluctance to operate due to high psychological pressure, so the application of this technology is limited
[0004] 2) When drug addicts are being checked, they often adopt the method of stealing the beam and changing the post, replacing their own urine sample with a normal person's urine sample or tap water, which reduces the reliability of the test
[0006] Up to now, do not find the public report identical with technical scheme of the present invention

Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with accompanying drawing: the infrared sensitive camera head (3) that is fixed on the light-shielding eye mask (1) picks up the pupil image illuminated by infrared light-emitting diodes (2, 4), and passes through the video signal cable ( 11) Send the signal to the input end of the video capture card (10). After the converted signal is processed in the computer (12), it is judged whether the subject has taken heroin. The red light emitting diodes (5, 6, 7) are connected to the battery (9) through the control switch (8), and when the control switch (8) is closed, the red light emitting diodes (5, 6, 7) are bright to stimulate the pupil. The battery (9) also supplies electric energy to the infrared sensitive camera (3) and infrared light-emitting diodes (2, 4).

[0042]In data processing, the signal first passes through the threshold window, and after spatial filtering, pupil features are extr...

Abstract

This invention relates to a quick test method for testing the dynamic changes of pupils of drug-dependents and its device, which transmits the image data of the pupil to a video signal collecting card on a computer in the mode of video signals to be converted to digital signals via video modulus for further image process to be compared with database to judge if the tested one takes drugs. The device is composed of glasses and a computer, among which, a plastic cover blade is set on the glasses, an infrared micro-camera head is fixed on the cover blade, infrared light sources composed of LED are set at both sides and three LED at the right of the blade, data collection and a software are put in the computer.

Description

Technical field: [0001] The invention relates to a rapid detection method and device for pupil dynamic changes of drug addicts, belonging to a neurobiological detection device. Background technique: [0002] At present, the detection of drug addicts in our country is mainly based on the routine bioanalysis of the urine or blood of the test object. This detection method requires a laboratory with certain conditions, a long detection time, and high detection costs. When extracting body fluids, it is necessary to ensure that the samples are The reliability operation is also more cumbersome. At present, my country has developed and produced testing boxes for urine testing of suspected drug addicts. Although the urine testing box has made great technological progress, there are many problems in the practical application of urine testing: [0003] 1) The operation of ensuring the accuracy of the sample during urine extraction is also relatively cumbersome, requiring special equip...
