Embodiment 1

[0018] Embodiment 1: a non-contact rapid detection system for drug addicts, including a camera device arranged on the security inspection machine or in front of the security inspection machine and the access control system, and a processor connected to the camera device. The processor includes a face recognition function, which can be used according to The image information acquired by the camera equipment recognizes and detects the human face, locates the position of the eyes of the detected person, and obtains the eye information of the detected person and the face information of the detected person. The eye information includes orbital size data and Pupil size data, the face information includes face size data, the processor is used to calculate the pupil size value based on the orbital size data, pupil size data and face size data, and compare the calculated pupil size value with the preset Comparing the pupil size with a good standard value, calculate the size of the pupil...

Embodiment 2

[0019] Embodiment 2: On the basis of Embodiment 1, further, the face information of the detected person is static image information, and the eye information of the detected person is dynamic image information within 1-2 seconds. An infrared luminous tube device and an illuminance meter connected to the processor, the infrared luminous tube device and the illuminance meter are installed at the same position as the imaging equipment or are integrated with the imaging equipment, and the infrared light wavelength emitted by the infrared luminous tube device is at the corresponding Within the wavelength range that is harmless to the human body, the illuminance meter is used to obtain light intensity detection in the current environment.

[0020]The processor is used to receive the infrared light image data emitted by the infrared light-emitting tube device through the camera equipment, and is used to calculate the red-eye effect value of the pupil of the detected person through the ...

Embodiment 3

[0024] Embodiment 3: A non-contact rapid detection method for drug addicts, comprising the following steps: S1, collecting the face image data of the person to be detected in front of the security inspection machine and the camera equipment installed in front of the access control system, and transmitting to Processor; S2. The processor receives the face image data of the person to be detected, and obtains the eye information and face information of the person to be detected, and obtains orbital size data, pupil size data and face size data; S3. Based on Calculate the pupil size value from the orbital size data, pupil size data and face size data, and compare the calculated pupil size value with the preset standard value, calculate the size of the pupil size value and the standard value, if it is greater than , or less than, it is judged that the detected person is a suspected drug addict, if it is the standard value, it is judged as a non-drug addict; S4, if the detected perso...

Abstract

The invention provides a non-contact rapid detection system and method for drug addicts. The detection system comprises a camera device and a processing apparatus connected with the camera device, wherein the camera device is arranged on a security inspection machine or in front of the security inspection machine and an access control system, and the detection system can also be used as a portablehandheld device. The human face can be identified and detected according to image information acquired by the camera device, the eye positions of a detected person can be located, pupil dynamic imagedata is collected for a period of time (1-2 seconds) to obtain various data such as the pupil P value, the R value, the T value and the Q value to be compared with data of normal people and drug addicts, and whether or not the detected person is a non-drug user is judged. According to the system and the method, identification and detection can be completed efficiently without contact, networkingreporting can be achieved, and a comprehensive technical support is provided for supervising, controlling and screening drug-related person of relevant departments. The detection rate is high, the detection can be completed within 2-3 seconds, the equipment cost is low, the equipment structure is small and exquisite, and detection and identification results are precise and reliable.

Description

technical field [0001] The invention relates to a rapid detection device or system equipment technology for drug addicts, in particular to a non-contact rapid detection system and method for drug addicts. 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. The applicant has been engaged in the research and development and production of portable drug addict detection equipment for a long time, and has applied for a number of patents on fast and portable detection equipment, such as the Chinese invention patent of CN201811050371.5, a high-precision detection rate drug addict pupil detector The technology disclosed in ...
