In this embodiment, as shown in fig. 5, the step of evaluating the garbage classification quality is to distinguish the type of the garbage can 2 according to the identified tag, call different anomaly characteristic code libraries to identify the picture according to different types, and finally generate an evaluation value of the classification quality according to the number of objects matched by the anomaly code libraries; in order to improve the recognition efficiency, the abnormal code library is stored in the memory of the control main board 8, and the control main board 8 performs local matching operation in an edge calculation mode, so that the efficiency is improved, and the analysis processing pressure can be distributed to each system, so that the operation pressure of the server is reduced. The abnormal object feature code library is synchronized with the latest feature code library of the server at regular time, and the feature code library of the server can perform image recognition training according to pictures transmitted by using field Jing Zhongshang, so that feature codes are continuously perfected, and the evaluation capability accuracy is higher and higher. The accuracy rate of garbage classification and identification depends on the establishment perfection of the feature library, and the system adopts a manual labeling and machine learning mode to continuously supplement the feature code library so as to achieve the effect of improving the identification rate. In the continuous operation process of the system, equipment can upload identification pictures of weighing operation each time to a server, the system can collect a large number of identification samples, workers can identify the samples and label the identification results, such as pericarps, material belts, glass bottles and the like, and meanwhile, the misidentification results are corrected, and a more accurate feature code library is finally obtained through label learning work of a large number of samples. And the feature code library is updated in the background at the non-working time of the system, so that the recognition capability of the system is ensured.
