If the review and verification fails, the first BIM model needs to be remodeled.

[0069] On the basis of the above embodiment, the VR-based technology, according to the first BIM model, the first VR virtual space includes:

[0070] Input the first BIM model into Fuzor software to generate a first VR virtual space.

[0071] In the embodiment of the present invention, the first BIM model is input into the Fuzor software, and further design changes are made to the first BIM model through the Fuzor software, components can be added and deleted, and components can be accurately moved and placed to achieve the best design The lighting conditions can also be adjusted to compare the impact of different lighting on different design schemes, and these changes can be reverse-synchronized into the BIM software. In the embodiment of the present invention, by designing in a VR environment, space awareness can be integrated into the decoration design scheme. This sense of space opens up a new design workflow that is different from traditional two-dimensional design, so as to achieve the best space Utilization and design effects.

The sign is verified, and if the verification is passed, a second BIM model is obtained.

[0074]In the embodiment of the present invention, after the VR file is generated by the Fuzor software, the VR file can be opened through the VR terminal for scheme comparison, and a variety of decoration schemes can be compared and selected in the virtual scene, so as to truly restore the reality and facilitate comparison and decision-making. For example, in the virtual scene, adjust the ceiling style, color matching, style, ambient color and lighting effect matching in the subway station. Further, the VR terminal is used to simulate the subway station's guide signs, fire evacuation signs, emergency equipment signs, station nameplates, signs, etc. in the virtual reality space, so as to verify the guide sign system and signage. In the embodiment of the present invention, since the clarity of the sign has a great relationship with the color used, the same size of the sign is viewed at the same viewing distance, and the larger the sign at the same viewing distance, the shorter the recognition time of people, and the shorter the identification time. The length and size settings depend on how long it is expected to take to complete the identification. Depending on the background color of the sign and the color of the text symbols on it, visibility and how long it takes to identify it can make a big difference. Generally speaking, the higher the warning level, the brighter the colors used and the greater the color contrast. Therefore, in the virtual scene, the identification sign can be better verified.
