侯妙乐：测绘遥感新技术让文化遗产在数字世界永生

Core Viewpoint - The integration of new technologies such as surveying and remote sensing is essential for the digital preservation and utilization of cultural heritage, allowing it to thrive in the digital realm while addressing its historical and contextual significance [1][2]. Group 1: Digital Cultural Heritage - Digital cultural heritage refers to the results of digitizing cultural assets, including images, videos, audio, and models, as well as the comprehensive use of technologies like surveying, geography, and artificial intelligence for information retention, processing, management, and application [1]. - The narrow definition of digital cultural heritage focuses on the digitization outcomes, while the broad definition encompasses integrated technologies for data, analysis, services, and application systems [1]. Group 2: Challenges and Solutions - The current 3D models produced in the cultural heritage digitization industry face challenges such as lack of interactivity, dynamic simulation, and effective spatiotemporal empowerment [2]. - The application of real-scene 3D technology is crucial for creating three-dimensional information products that are spatially, physically, and realistically represented, which can enhance the activation and utilization of cultural heritage [2]. Group 3: Practical Applications - The team led by Hou Miaole has collaborated with various institutions to establish multi-layered semantic models for cave heritage, addressing different needs such as archaeology, protection, and utilization [3]. - The practical work includes the digitalization and virtual restoration of the Dazu Rock Carvings, emphasizing the importance of having spatiotemporal semantic information for intelligent virtual restoration [2][3].
