AI Technical Summary
Existing technologies cannot effectively solve the problems of accurate positioning and synchronous alignment of prefabricated components in the composite side wall structure of prefabricated subway stations, especially the challenges of hoisting accuracy and safety for large-sized and heavy components.
The system combines a hole positioning device, a camera, and an intelligent lifting device. The target is brought into the camera's field of view through the hole positioning device, and machine vision technology is used to calculate the pose correction of the reinforcing bar, so as to achieve the alignment and insertion of the reinforcing bar and the corrugated pipe.
It has enabled unmanned assembly and hoisting processes, improved assembly accuracy and construction quality, and solved the problems of accurate positioning of invisible holes and coordinated assembly of multiple holes.
