Assist the digital transformation of scenic spots. Use WebGL technology to create scenic pictures with complex 3D structures, which can also be easily loaded on the browser.

The buildings in the Forbidden City in Beijing are divided into two parts: the outer court and the inner court. The center of the Outer Dynasty is the Hall of Supreme Harmony, the Hall of Zhonghe, and the Hall of Preserving Harmony. The center of the inner court is Qianqing Palace, Jiaotai Palace and Kunning Palace. Based on the layout of the Forbidden City, a 3D antique scene is built, and magpies and flying white cranes are used to set off the classical style, reflecting the harmonious coexistence of man and nature. Combined with sci-fi color matching, the Forbidden City with red bricks and yellow tiles is used to describe the long history of China. Accessing VR devices for tours can achieve an immersive effect and bring an immersive experience.

System analysis

General Information

The "net" icon in the 3D scene can be clicked to drill down to the people flow interface of the public toilet to display the number of people in line. Tupu software HT supports model rendering in various ways, adopts lightweight 3D modeling technology, based on 3D scenes, supplemented by 2D data panels, and counts the number of users of men's toilets, women's toilets, and barrier-free public toilets; the public toilet load in each area ; Environmental scoring history; Nitrogen, temperature, humidity, PM2.5 and other environmental data; Realize digital management of scenic spots.

Admission Statistics

The online ticket booking, on-site ticket purchase, and the number of people leaving the park are separately counted, and the data of intelligent monitoring equipment and face recognition are connected to the Tupu software visualization system to realize active security. Operation and maintenance can always pay attention to the tourist data in the visualization system, and control the number of tourists in the park within a reasonable range, which is convenient for epidemic prevention and control. As a component library based on HTML5 standard, Tupu software HT can seamlessly integrate various multimedia functions of HTML5, supports the integration of various video resources to form a unified video stream, and can mark camera objects on 2D and 3D situation maps and associate their video signals The corresponding monitoring video is retrieved through scene interaction to meet the monitoring needs of operation and maintenance personnel for real-time situational awareness of the scene, retrospective comparison of historical data, and emergency response plans.

The actual number of admissions

The historical gradient-colored triangular bar chart realizes the year-on-year, month-on-month and real-time data display of the average daily admissions. Tupu uses graphical means to interpret and convey data information clearly and effectively, helping us to discover the laws and characteristics and to mine the value behind the data.

clean hand load

The green progress bar shows the load rate percentage of Shenwumen East, Shenwumen West, Qianqing Palace East, and Yuyuan Garden. When the load exceeds 80%, the progress bar turns yellow, and when the load exceeds 90%, the progress bar turns red. Through the combination of HT for web and GIS, operation and maintenance can use the large visual screen of Tupu software to view the crowded location, and transmit the location information to security personnel through wearable devices such as smart bracelets.

Nearby parking lot pressure

There is no parking lot in the Forbidden City, and the surrounding public parking lots are also far away, so it is not recommended to drive there. If you come by car, you can park at the parking lot of Xihuamen, the National Grand Theater, the parking lot of Zhongshan Park, and the parking lot of Beijing Hotel. The parking status of the parking lot is displayed in the form of a good seal, which can be combined with the ticket booking system to send the parking information to the tourists who have booked tickets through the applet.

Bus pressure near each door

Statistics on the bus conditions of Meridian Gate, Shenwu Gate, Donghua Gate and Xihua Gate are convenient for tourists to travel.

Today's event handling

Statistics of events that have been processed, to be dispatched, found, and to be dispatched to the police can evaluate the performance of scenic spot management personnel and optimize personnel management.

Analysis of the reasons for complaints

The dynamic radar chart shows the number of tour guide services, tour guide violations, traffic problems, facility problems, and tour group violations. Tupu software HT visualization uses rich charts, graphics and design elements to display relatively complex and abstract data in a more intuitive and understandable form in a visual way, which is convenient for scenic spot management.

Heatmap

The crowd density in the scenic spot is getting higher and higher, the mass incidents are increasing day by day, and the dense flow of people has increased the difficulties in the management of security and services. Through the image recognition analysis of multiple smart cameras, a complete thermal map of the park can be formed. It shows the concentration of people and the degree of crowding in a certain part of the park. People gather in the red area, and there are fewer tourists in the green area. Crowd density analysis uses advanced target detection, identification, tracking and other technologies to count the number and density of crowds and other characteristic indicators, to monitor the safety of crowds in public places, and to help us grasp the correct crowd density data and trends, so as to carry out reasonable security management . By monitoring passenger flow through Hightopo, managers can establish a passenger flow early warning mechanism, effectively guide and evacuate the passenger flow that exceeds the carrying capacity of the scenic spot, and consider crowd evacuation routes in advance.

Evacuation Simulation

The dynamic arrow points to the direction of the escape exit, which can simulate multiple evacuation routes and predict the time to calculate the best escape route. The scenic spot has the characteristics of high density of people and complex terrain, so the length of evacuation time is directly related to the safety of personnel. By combining HT for Web and BIM, with the help of sensor equipment and radio frequency identification technology, the escape data of personnel is determined, and the three-dimensional data of Hightopo is used to determine the escape data of personnel. The visualization features restore the real evacuation environment and evacuation situation, which is highly in line with the real situation of the scenic spot. Therefore, in the actual disaster escape, the escape efficiency of tourists can be effectively improved.

GIS switch

The combination of HT for Web and GIS can make the ground objects in the 3D scenic spot show more details. The 3D scene data can be acquired through aerial photography modeling or artificial modeling. Aerial photography modeling is three-dimensional oblique photography. Using aircraft or drones to carry multiple sensors, the objects are photographed and collected from five directions, front, rear, left, right, and vertical. The 3D model is obtained by processing operations such as correction, adjustment, and multi-view image matching. Manual modeling is mainly based on a certain range of scene graphs or CAD drawings combined with real photos for artificial modeling.

The result data of aerial photography modeling has geographic coordinate system information, which can be accurately matched with GIS. To match the artificial modeling with GIS, manual spatial correction and registration is required. The .osgb model data of aerial photography modeling has multiple levels of detail (LOD). The system can display LOD level models with different precisions according to the distance between the user and the scene, which improves the efficiency of data display and rendering.

Aerial photography modeling is not as precise as manual modeling. If it is necessary to query, analyze and edit simple models, the aerial photography needs to be processed individually, but the restoration requires a longer period and higher cost. Therefore, the single processing is applied to key buildings or monuments.

The HT for Web GIS product supports the loading of different map tile services or data, 3DTiles format data of aerial oblique photography real scenes, and different GIS data such as urban buildings. With the technical advantages of seamless integration and other technical advantages, the massive POI data, traffic flow data, planning data, current situation data, etc. HT for Web GIS can also assist in urban flood control management and build smart cities.

Summarize

The epidemic has accelerated the digital transformation of the cultural tourism industry, and cloud tourism, cloud exhibitions, immersive performances, and immersive entertainment have become a trend. Parks and scenic spots can make full use of artificial intelligence, virtual reality and other technologies to digitize cultural tourism resources, so that tourists can have an immersive and interactive experience before and during travel. For the cultural tourism industry, Metaverse is a medium that breaks the concept of time and space in tourism, and is more like a virtual experience place for themed culture.
