Abstract

The invention discloses an inspection interaction control method based on three-dimensional live-action virtual-real mapping, belongs to the technical field of industrial inspection and digital operation and maintenance, and aims to solve the problems of virtual-real space interaction splitting, model updating lagging and control closed loop deficiency in a traditional inspection mode. A system integrating laser scanning and positioning is used for collecting live-action data and constructing a high-fidelity three-dimensional live-action model, then high-precision feature matching and space alignment are carried out on the high-fidelity three-dimensional live-action model and a preset virtual inspection model, a stable virtual-real mapping relation is established, an operator can input a control instruction in a natural interaction mode, and the real-time performance of the system is improved. According to the mapping relation, the instruction is analyzed into specific control parameters for the physical scanning system, the physical scanning system is driven to adjust the scanning posture or path so as to pertinently collect and update data, and the three-dimensional live-action model is fused and updated in real time. According to the method, accurate linkage of virtual and real spaces and dynamic enhancement of the model in the inspection process are realized, and the interactivity, the real-time performance and the intelligent level of inspection are remarkably improved.
