Problems solved by technology

[0002] my country's tunnels have ushered in large-scale construction, and tunnel construction has entered a period of rapid development. However, at the same time, the uneven technical capabilities of tunnel construction personnel and the low talent reserve have had a certain impact on the quality of tunnel construction. Learning and mastering the tunnel construction process is slow, making teaching and engineering technology training imminent
During the production practice of students majoring in underground engineering and other majors, due to various problems such as safety and production progress, they just watched the static tunnel construction machinery in the tunnel and understood part of the tunnel construction process, but could not understand the whole process, let alone experience the tunnel construction process. The position and conversion relationship of time and space makes the practice effect half the effort; and because the on-site practice or practice is dangerous and lacks safety guarantees, it also makes the learning and training of tunnel construction technology unsatisfactory. Engineering geological disasters such as water inrush and water gushing have caused huge casualties and property losses, but technical personnel cannot respond to emergencies well due to insufficient training time and quality

Abstract

The invention discloses a tunnel construction virtual teaching system and method based on three-dimensional laser scanning modeling. The three-dimensional laser scanner performs laser scanning to obtain three-dimensional point cloud data on the surface of tunnel objects and transmits them to a computer; the computer performs three-dimensional numerical modeling to This is to obtain a high-precision and high-resolution tunnel space structure model; the virtual reality helmet receives the signal data sent by the computer and displays it on a three-dimensional image. The invention has the advantages of simple equipment, convenient operation and small space occupation, and can simulate and display the tunnel construction process through virtual display technology, which not only eliminates the danger of on-site practice, but also achieves an immersive effect through its good visual effect.
