Camera equipment layout: arrange the camera equipment in the exhibition hall to ensure that the required scene can be fully captured. If you use a laser scanner, you need to consider the scanning angle and density.
Data collection: actual data collection, taking photos or laser scanning to obtain detailed records of the exhibition hall.
Second, data processing and reconstruction: image processing: if you use a camera to shoot, you need to process the image, including color correction and denoising.
Point Cloud Generation: If a laser scanner is used, point cloud data is generated, which is a set of three-dimensional coordinates of points, representing the surface of the exhibition hall.
Three-dimensional reconstruction: use professional three-dimensional reconstruction software to convert the collected images or point clouds into three-dimensional models. This may involve dense matching, multi-view stereo matching and other algorithms.
3. Environment modeling and design: Import 3D model: Import the generated 3D model into the development platform of virtual environment.
Refine the model: refine the model to ensure that the model accurately reflects the appearance and structure of the actual exhibition hall.
Add details: according to needs, add some details, such as furniture, decoration, etc., to enhance the realism of the virtual exhibition hall.
Fourth, user interaction and function addition: interaction design: design the interaction mode of users in the virtual exhibition hall, including navigation and information viewing.
Function addition: according to the needs of the exhibition, add some functions, such as information display of exhibits, navigation system, etc.
V. Release and display: Release the application: package the virtual exhibition hall into an application suitable for VR or AR platform.
Display and promotion: display the virtual exhibition hall in a suitable occasion, which can be displayed by VR head display, tablet computer and other equipment. At the same time, it is promoted online or offline.
