Abstract

The invention discloses a tunnel construction virtual teaching system and method based on three-dimensional laser scanning modeling. The tunnel construction virtual teaching system comprises a three-dimensional laser scanner, a computer and a virtual reality helmet, wherein the three-dimensional laser scanner conducts laser scanning, acquires three-dimensional point cloud data of tunnel object surfaces and transmits the data to the computer; the computer conducts three-dimensional numerical modeling to acquire a tunnel spatial structure model with a high precision and resolution ratio; the virtual reality helmet receives signal data sent by the computer and conducts three-dimensional image display. According to the tunnel construction virtual teaching system and method based on three-dimensional laser scanning modeling, equipment is simple, operation is convenient, occupied space is small, a tunnel construction process can be simulated and displayed through a virtual display technology, not only are the dangers of field practice removed, but also a good visual effect and an immersive effect are achieved.

Description

technical field [0001] The invention relates to the technical field of virtual teaching, in particular to a tunnel construction virtual teaching system based on three-dimensional laser scanning modeling technology. Background technique [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...
