Abstract

The present invention discloses a cloud measurement method for a hydraulic support group based on AR calibration and matching, which includes a physical system, a remote cloud data processing system and a VR system. In the physical system, AR glasses provide an interactive interface for virtual-reality interaction and data display, and the inspection worker completes the inspection by manually matching and dragging the MRTK toolkit. In the remote cloud data processing system, the cloud service computing system performs data storage and preliminary analysis, and the centralized control worker and the GPT decision system send the mixed decision results to the AR glasses after secondary data processing to request additional inspection data, and finally the on-site inspection worker completes the measurement. In the VR system, a twin hydraulic support group model is constructed and corrected, the overall workspace is constructed, and the posture reconstruction accuracy is verified, thereby realizing real-time measurement of the virtual posture of the hydraulic support group.
