Problems solved by technology

In view of this situation, the current solution is to increase the similarity threshold between the spectral data of the sample in the database and the spectral data of the substance to be tested. Due to the influence of various factors, only by increasing the similarity threshold of matching, the substance to be tested that originally belonged to the known sample in the database is often misjudged as an unknown substance

Abstract

The present application relates to the field of substance detection, and in particular to a method, device and terminal for substance detection and a readable storage medium. The method for substancedetection comprises: obtaining the spectral data of a substance to be tested; determining a matching result of the substance to be tested and matching samples in a database according to the spectral similarity of the spectral data of the substance to be tested and the spectral data of each sample in the database, wherein the database includes the spectral data and the attribute information of a known sample, as well as the spectral data and the attribute information of a unknown sample; and determining the detection result of the substance to be tested according to the matching result. The method reduces the probability of misidentification of the substance to be tested.

Description

technical field [0001] The present application relates to the field of substance detection, in particular to a method, device, terminal and readable storage medium for substance detection. Background technique [0002] The current process of identifying the substance to be measured is: obtain the spectral data of the substance to be measured, and match the spectral data of the substance to be measured with the spectral data of the known substance. If the similarity with the spectral data of the known substance exceeds similarity threshold, it is determined that the substance to be tested is a known substance. [0003] The inventor found in the process of studying the prior art that the number of known substances contained in the current database for substance detection is still very small. If the spectral data of a substance to be tested does not exist in the database, but in the database When a substance is tested for a substance, since the spectral data of the substance t...
