Molecular recognition method and system

The invention provides a molecular recognition method and system, and relates to the technical field of molecular detection.The method comprises the steps that an STM image of a to-be-detected sample is obtained; the STM image is input into a trained first model to obtain first identification information, and the first identification information represents the position and the morphological category of each molecule in the to-be-tested sample; obtaining a target TERS spectrum of each molecule in the sample to be detected; the target TERS spectrum is input into a trained second model, second identification information is obtained, and the second identification information represents a spectrum classification result of the target TERS spectrum; and according to the first identification information and the second identification information, analyzing to obtain the molecular species of the to-be-detected sample. 本公开提供一种分子识别方法及系统，涉及分子检测的技术领域，该方法包括：获取待测样品的STM图像；将STM图像输入已训练的第一模型中，得到第一识别信息，其中，第一识别信息表征待测样品中每个分子的位置和形态类
