AI Technical Summary

Technical Problem

The existing integrated pipeline alignment assembly method has problems of poor accuracy and low efficiency in the preliminary alignment and measurement and correction steps, and it is impossible to monitor the construction process in real time to ensure construction quality.

Method used

A digital construction method based on machine vision is adopted, and the initial positioning and precise positioning of the pipe gallery segment is achieved by setting reflective signs and positioning marks on the pipe gallery segment and using multiple cameras for image tracking and comparison. At the same time, the pipe gallery adjustment device is used to automatically adjust according to the camera image data to ensure the accurate alignment of the pipe gallery segments.

Benefits of technology

It has achieved the accuracy and efficiency of the alignment assembly of pipe gallery segments, can quickly complete the alignment assembly, and ensure construction quality through real-time monitoring.

Abstract

The invention discloses a comprehensive pipe gallery digital construction method based on machine vision, and relates to the field of underground or underwater structures, and the comprehensive pipe gallery digital construction method comprises the following steps: respectively arranging a first reflective sign and a second reflective sign at four inner corners of a first pipe gallery section and a second pipe gallery section; four cameras are arranged in the comprehensive pipe gallery, and the installation positions of the cameras are calibrated through first reflective signs; the second pipe gallery section is adjusted, so that in the second image, each second reflective sign and the corresponding first reflective sign coincide with each other, and preliminary positioning is completed; the pipe gallery adjusting device adjusts the position of the second pipe gallery section according to the image data of the camera, so that the positioning marks in the second image are consistent in size; meanwhile, in the third image, the scale line of the positioning mark and the scale line of the lens coincide with each other, and precise positioning is completed. It can be seen that the pipe gallery construction is monitored through the digital image technology, alignment assembly of the pipe gallery sections can be accurately and rapidly completed, and the quality of the pipe gallery construction is improved.
