Problems solved by technology

[0003] However, there are still many shortcomings in the actual application of the above-mentioned technical solutions. When using hyperspectral imaging to detect methamphetamine, heroin and marijuana, due to the similarity of itself and the influence of surrounding environmental factors, it cannot be effectively detected. Lead to less accurate detection results, reducing its practicability

Abstract

The invention discloses a hyperspectrum-based methamphetamine, heroin and hemp detection method and belongs to the field of drug detection. According to the method, a central processing module is adopted; the input end of the central processing module is connected with an image acquisition module; the output end of the central processing module is connected with an information display module; theconnecting end of the central processing module is connected with an image storage module and a model establishing module; and the output end of the central processing module is connected with an intelligent analysis module. According to the method of the invention, based on overall design, a series of operations such as impurity removal, correction and brightness adjustment are performed on an image through the central processing module, so that a comprehensive hyperspectrum image can be formed, and a model is built; the built model is optimized with an image optimization unit, so that the built model is more perfect. The method can be used for more accurately and effectively detecting objects such as methamphetamine, heroin and hemp on the whole, so that more comprehensive detection information is obtained.

Description

Technical field [0001] The present invention relates to the technical field of drug detection. More specifically, the present invention relates to a method for detecting methamphetamine, heroin and marijuana based on hyperspectral. Background technique [0002] At present, drugs are the most harmful to people. Drugs generally refer to drugs that make people addicted. The term drug here is a broad concept. It mainly refers to opium, heroin, methamphetamine, marijuana, etc. abused by drug users, and also includes dependents. Sexual natural plants, tobacco, alcohol, and solvents are different concepts from medical drugs. Generally, hyperspectral imaging is required for the detection of methamphetamine, heroin, and marijuana. [0003] However, the above technical solutions still have many shortcomings in actual application. When using hyperspectral imaging to detect methamphetamine, heroin and marijuana, due to their own similarity and the influence of surrounding environmental factors...
