Description

Technical Field

[0001] The present invention relates to the technical field of digital intelligent tourism, and in particular, to a digital tour guide device and system for tourist scenes based on virtual reality. Background Art

[0002] Digital tourism and intelligent tourism are the two core directions of the digital transformation of the tourism industry. Digital tourism focuses on using technologies such as virtual reality (VR / AR), big data, and 5G to digitally reconstruct tourist scenes and services. For example, virtual scenic spot tours can be realized without leaving home through VR, or digital twin technology can be used to optimize scenic spot management. Its core lies in breaking physical limitations and providing an integrated online and offline experience, such as electronic ticketing, digital map navigation, and digital protection of cultural heritage. Intelligent tourism is based on technologies such as artificial intelligence (AI), the Internet of Things (IoT), and big data analysis, aiming to achieve the automation and personalization of tourism services. For example, AI can generate itinerary plans according to user preferences, IoT devices can monitor the scenic spot environment in real time, and big data can dynamically regulate the tourist flow. Its core is to improve service efficiency through intelligent technologies, such as intelligent guided tours, personalized recommendations, and smart scenic spot management.

[0003] The two are deeply integrated in practice. Digital tourism provides a data foundation for intelligent tourism, such as tourist behavior portraits, and intelligent technologies further optimize the digital experience, such as AR navigation with AI voice commentary.

[0004] The existing intelligent digital tour experience mainly includes the following technical problems: the information presentation dimension is single. Traditional guided tours rely on voice explanations, graphic display boards, or simple AR overlays, and it is difficult to achieve multi-modal information fusion, such as the three-dimensional restoration of historical scenes and the perspective of the internal structure of cultural relics. Tourists cannot obtain a time-travel experience, and their understanding of abstract cultural connotations (such as architectural techniques and historical events) remains on the surface; the passivity and inefficiency of interaction. Fixed-route guided tours limit the freedom of exploration, and tourists cannot interact deeply according to their interests. Technical fragmentation and experience fragmentation; insufficient coordination between AR / VR devices and physical scenes. Mobile phone AR needs to be aligned with markers, there is a displacement error between the content of MR glasses and the real scene, and data interconnection has not been achieved for naked-eye 3D projections, handheld terminals, and wearable devices, resulting in redundant operations; the lack of barrier-free guided tours. Existing systems lack multi-sensory interaction channels. Visually impaired groups cannot perceive the contours of exhibits through tactile vibrations, and hearing-impaired groups lack real-time sign language translation overlays. Summary of the Invention

This flexibility ensures the precise matching of the projection content with the physical scene. For example, in complex terrains or dynamic scenes, such as moving tourists or changing lighting conditions, the clarity and stability of the projection can still be maintained. The protection and occlusion component is movably installed at the laser projection component and can automatically occlude or protect the projection device according to environmental conditions. This not only improves the durability of the device but also reduces device damage or failures caused by environmental factors and lowers the maintenance cost. The measurement and sensing component is installed within the projection range of the laser projection component, monitors the projection effect in real time, and through the communication connection with the laser projection component, feeds back data for optimized calibration. This real-time feedback mechanism ensures the high-quality presentation of the projection content. For example, in the case of light changes or tourist movement, the projection parameters can be quickly adjusted to maintain the best effect. The measurement and sensing component can also sense changes in the surrounding environment and feed the data back to the laser projection component and the alignment control component to dynamically adjust the projection parameters. This adaptability enables the projection content to better blend into the physical scene. For example, it can automatically enhance the projection brightness at night or in a dimly lit environment, or adjust the contrast under strong light conditions to ensure that tourists always obtain a clear visual experience.

[0066] The laser projector blows air towards the side away from the device through a cooling fan, quickly removing the heat generated during the operation of the device. This cooling design effectively avoids the performance degradation or damage of the device caused by overheating, ensuring the stability and reliability of the laser projector during long-term operation. The focusing lens is installed at the front end of the laser projector and can dynamically adjust the focal length according to the projection distance and scene requirements to ensure the clarity and detail presentation of the projected content. The moving track is fixedly installed on the facilities of the tourism physical scene, and the moving frame moves along the track. The rotating frame and the swinging frame are combined and installed on the moving frame, providing the laser projector with multi-dimensional flexible adjustment capabilities. This design enables the projected content to accurately match the physical scene. Through the combination of the moving frame, the rotating frame and the swinging frame, the laser projector can achieve high-precision positioning and dynamic tracking, ensuring that the projected content is always perfectly integrated with the physical scene. The protective shell is sleeved around the laser projector, and the lens cover is movably installed on the protective shell and can block the projection lens of the laser projector as needed to prevent damage to the device caused by dust, rain or other environmental factors. The protective cover covers the moving frame, the rotating frame and the swinging frame to further protect the mechanical components of the device and extend its service life. The protection and shielding component can be adjusted automatically or manually according to environmental conditions. The protective shell and the protective cover provide additional protection. This design not only improves the adaptability of the device, but also reduces the maintenance difficulty and cost. The laser distance measuring head is installed at the front end of the laser projector and detects the distance towards the projection direction to ensure the accurate positioning of the projected content. The infrared sensor head detects towards the side of the laser projector and can sense the changes in the surrounding environment, providing real-time data for the system. The point cloud recognition head detects towards the projection direction to identify the scene features and further optimize the matching degree and fusion degree of the projected content. The measurement and sensing component dynamically adjusts the position, angle and focal length of the laser projector by detecting and feeding back data in real time to ensure the perfect integration of the projected content with the physical scene and maintain the clarity and stability of the projection. The coordinated work of the laser distance measuring head, the infrared sensor head and the point cloud recognition head provides the system with comprehensive environmental perception capabilities. This intelligent optimization function not only improves the projection effect, but also enhances the adaptability and reliability of the system, providing tourists with a higher-quality immersive experience.
