Museum Cloud Exhibition Smart Cloud Project Modeling Plan

At present, public demand for cultural experience has transformed from "offline on-site visits" to "in-depth online exploration". Traditional physical exhibitions are increasingly constrained by limitations in time, space and carrying capacity. Meanwhile, the Outline of the 15th Five-Year Plan clearly proposes to "advance digital-intelligent empowerment and informatization transformation for cultural development", listing smart museum development and digitalization of cultural heritage as core development priorities.

Nevertheless, the museum industry still faces multiple challenges: physical exhibition halls are restricted by opening hours and physical space, failing to reach broader audiences; cultural relic display is limited by showcases and exhibition lines, unable to satisfy visitors’ demands for refined viewing of artifact details; museum operation & management lack real-time data support, with environmental monitoring and passenger flow management still relying on conventional means. Against this backdrop, building a museum cloud exhibition hall centered on 3D modeling & VR display and integrated with IoT sensing capabilities becomes a pivotal path to drive smart transformation of museums.

• Digital Twin Platform: Supports 3D model construction, scene rendering and visual interactive operations

• Data Governance Platform: Enables fusion, governance and asset accumulation of multi-source heterogeneous data

• Intelligent Service Platform: Delivers immersive exhibition viewing, intelligent navigation and other application services for visitors

N Types of Applications: Cover diverse business scenarios including smart services, smart management and smart heritage protection.

II. Core Construction Contents

2.1 3D Modeling & VR Cloud Exhibition Hall

2.1.1 3D Digital Recreation of Exhibition Halls

Relying on high-precision 3D modeling, digital twin technology and AI spatial reconstruction algorithms, the layout structure and spatial dimensions of offline exhibition halls are captured accurately. Integrated technologies including laser scanning and panoramic shooting realize mm-level digital reconstruction, completing digital twin replication of the whole museum’s architectural structure, exhibition layouts and surrounding landscapes. Key exhibition area models are refined down to component level to ensure high visual and spatial fidelity of virtual scenes.

2.1.2 3D Digital Modeling of Cultural Relics

High-precision 3D scanning and digital reconstruction are conducted for key museum collections. Technologies such as structured light scanning, 3D photogrammetry and AI 3D Gaussian Splatting are adopted to build μm-level precision digital archives for cultural relics. The 3D artifact models support visitors to perform free interactive operations including 360° rotation and zoom-in via multi-terminals, delivering an immersive experience of "close-up access" to artifact details.

2.1.3 VR Immersive Roaming Experience

Based on 3D digital twin technology and cloud rendering capabilities, physical exhibition halls are fully mapped to cloud exhibition spaces. Visitors can conduct immersive free roaming from a first-person perspective via PC, mobile, tablet and other multi-terminals. The system provides dual modes: autonomous roaming and intelligent guided tour. Autonomous roaming allows users to move freely within cloud exhibition ranges, with auxiliary functions including click-to-view, navigation guidance and digital maps; digital human guides deliver intelligent voice commentary to create an intelligent, companion-style exhibition experience.

2.1.4 Cross-Platform Multi-Terminal Adaptation

Supported by terminal-cloud rendering and lightweight engine technology, the cloud exhibition hall achieves smooth access and display on mobile phones, PCs, tablets and other terminals. The mini-program version features compact size and simple operations to meet mobile access and touch control demands; the PC version satisfies in-depth browsing and large-screen exhibition viewing requirements. The cloud exhibition hall supports free 7×24-hour "cloud exhibition visits", breaking time-space constraints of physical exhibitions.

2.2 IoT Sensing System

2.2.1 Environmental Monitoring

Hardware monitoring sensors for temperature/humidity, illumination and ultraviolet rays are deployed in exhibition halls, showcases and warehouses to real-time monitor cultural heritage safety indicators including temperature, humidity, light and UV radiation across venues, exhibition zones and halls. The system triggers instant alarms upon any abnormality and notifies staff for immediate disposal. Environmental data is synchronized to the cloud exhibition hall management backend to provide data-driven decision support for cultural relic protection.

2.2.2 Passenger Flow Monitoring & Analysis

Passenger flow data of all museum zones is collected in real time via passenger flow cameras, ticket turnstiles, infrared passenger counters and other acquisition devices. The system intuitively presents passenger volume fluctuations and trends via time-series charts, enabling precise daily visitor volume forecasting. Meanwhile, user portrait analysis calculates average visiting duration, age distribution, interest preferences and other visitor metrics, offering data basis for exhibition layout optimization and improved commentary services.

2.2.3 Data Visualization Cockpit

A unified museum data visualization platform is built to dynamically converge multi-source data including environmental monitoring metrics, passenger flow data and equipment operation status, displayed centrally on large screens via visual charts. Managers can "overview the whole museum via one screen and capture trends with one click", gaining real-time control over core indicators including safety status, equipment operation, environmental metrics and passenger flow heatmaps.

2.3 Intelligent Services & Interactive Experiences

2.3.1 Intelligent Navigation & Personalized Recommendation

Based on spatial computing technology and AI algorithms, the system generates personalized visiting routes in real time according to visitors’ interest preferences (e.g., bronze ware or modern history). Combined with high-precision 3D maps and Bluetooth positioning technology, meter-level accurate navigation is realized; visitors can directly navigate to target exhibition zones via voice commands or touch operations with one click.

2.3.2 Cultural Relic Interaction & Knowledge Exploration

Visitors may click any exhibit in the cloud exhibition hall to trigger automatic voice commentary and graphic-text introductions. Key cultural relics support 4× HD zoom function, allowing visitors to examine artifact details remotely anytime. Selected exhibits feature interactive Q&A, knowledge quizzes and other gamified functions to boost visitor engagement and learning experience.

2.3.3 AIGC Intelligent Q&A

An intelligent Q&A system is built upon large language models and museum collection knowledge bases to instantly respond to visitor inquiries regarding artifact specifics, historical backgrounds and other content. The system supports multi-modal interaction via text and voice, delivering efficient and convenient knowledge exploration experiences for visitors.
