In addition, traditional survey results are usually presented in the form of plane drawings or two-dimensional data, which makes it difficult to intuitively reflect the three-dimensional information of the terrain, which poses a considerable challenge to engineering design and construction. With the rapid development of virtual reality technology, VR technology has gradually been applied to various fields, especially in the fields of engineering design and construction surveys. VR technology has demonstrated its unique advantages.
