Intelligent acceptance method of steel mesh binding wire binding quality based on computer vision

Abstract

The invention discloses an intelligent acceptance method for the quality of steel mesh wire binding based on computer vision. It includes the following steps: first, train a target detection model that can identify the steel bar segments and node binding status between steel mesh nodes; second, design a computational geometry algorithm and use the recognition object to analyze the geometric characteristics of the steel mesh; finally, compare the standard binding schemes of the steel mesh, Find out the missing nodes, calculate the pass rate index, and intelligently evaluate the binding quality of the steel mesh. The present invention aims at the problems of low efficiency and poor accuracy in the current acceptance method of using manual observation, judgment, counting the number of missing reinforced steel nodes and evaluating the binding quality after preparing the concrete pouring warehouse. Based on the target detection technology in computer vision and the method theory of computational geometry, an intelligent evaluation method for the quality of steel mesh binding in the preparation and acceptance of concrete pouring warehouses was established, which has great application and promotion value in the field of civil engineering.

Description

technical field [0001] The invention relates to the field of construction information of civil and water conservancy projects, in particular to a method for intelligently checking and accepting the binding quality of steel mesh binding wires based on computer vision. Background technique [0002] In the construction of civil and water conservancy projects in my country, the preparation of the concrete pouring warehouse needs to bind the nodes of the steel mesh with wire as required. The quality of the binding directly affects the quality of the finished building after the concrete is poured. Therefore, it is an important part of the quality control of concrete pouring warehouse to check and accept the binding quality of steel mesh binding wires to ensure that the binding conforms to the specifications. [0003] In the process of warehouse preparation, the nodes of the steel mesh need to be fixed with binding wires according to the corresponding regulations. There are general...

AI Technical Summary

Problems solved by technology

The current quality acceptance of steel mesh binding wire binding is mainly through the on-site observation of the acceptance personnel to find out and raise binding problems. Faced with hundreds of binding nodes, the acceptance personnel take a long time to check and accept, which affects the construction progress; points that do not meet the specifications are easily missed. , the quality of acceptance is difficult to control; checking a large number of simple and repetitive things for a long time is easy to form irritability and affect the mental health of workers

Therefore, the current technical means are difficult to meet the requirements of engineering site automation and high-efficiency steel mesh storage bundling quality control and acceptance
