[0023] Specifically, a virtual reality implementation method for large-scale power review includes the following steps: Step S101, obtaining the two-dimensional design data of a large substation, performing hierarchical module splitting on the two-dimensional design data to obtain two-dimensional data of multiple module parts, and performing parametric modeling to obtain three-dimensional model data.

[0024] In an embodiment of the present invention, two-dimensional design data of a large substation is obtained, and then the two-dimensional design data is split into modules in the form of primary splitting, secondary splitting, tertiary splitting, etc. according to the terminal level requirements to obtain two-dimensional data of multiple module parts, and multiple module part model data are obtained by parametric modeling of the two-dimensional data of the multiple module parts, and then the multiple module part model data are integrated to obtain three-dimensional model data.

[0033] In an embodiment of the present invention, by receiving a first pointer roaming operation of a user on a handle for a roaming substation model, the handle responds to the first pointer roaming operation, emits a colored light beam at the tail to simulate a laser beam, points to an object patch in the roaming substation model, and determines the position distance of the pointed object, thereby performing a virtual scene teleportation of electric power review in the roaming substation model. A second pointer roaming operation of a user on a miniature substation model can also be received on the handle.
