Engineering test piece rapid identification method and system

Abstract

The invention relates to an engineering test piece rapid identification method and system, and belongs to the technical field of the electronic communication technology and engineering identification.The method comprises the steps that a test piece is marked and identified, the surface of the test piece is directly scanned, surface identification features are extracted, stored, transmitted and shared with other networked terminals, and the networked terminals scan the test piece and are matched with image attributes of the test piece to identify the test piece. The system comprises a mobile terminal which is carried with a technician conducting engineering activities and used for scanning the surface of the engineering test piece in the detection and maintenance processes in the construction and operation stages of highway and water transportation engineering projects, extracting the surface identification features of the test piece, storing, transmitting and sharing the surface identification features with other networked terminals, and the networked terminals scan the test piece and are matched with image attributes of the test piece. The system further comprises a server connected with the mobile terminal and used for receiving and storing the identification feature data of the engineering test piece. By means of the method and system, attribute information of the test piece can be accurately obtained, more labeling information on the test piece is not needed, and the method and system are suitable for wide application.

Description

technical field [0001] The invention belongs to the technical fields of electronic communication technology and engineering identification, and relates to a method and system for quickly identifying engineering test pieces. Background technique [0002] During the construction and operation stages of highways, water conservancy and other projects, physical cores are often produced or sampled. The traditional method is to mark the test piece with a marker pen or paste an information label. There are risks such as unclear erasure of the mark, loss of the information label, and damage. , the lack of information causes confusion, the source cannot be judged, and a one-to-one correspondence is formed, which is not conducive to blind sample management. [0003] In the prior art, the location is usually scanned by scanning a barcode or a two-dimensional code, which is more accurate and can transmit information in one direction. However, it is necessary to paste the two-dimensional...

Problems solved by technology

However, it is necessary to paste the two-dimensional code information on the test piece in advance, and after maintenance, the barcode or two-dimensional code has been damaged and dropped after a long period of transportation, and cannot be scanned and identified

Radio frequency identification technology, although it can identify specific targets and read and write related data through radio signals, it also needs to paste labels on the test pieces
