| Online Field Trip Applications of the Web Platform for Real-scene 3D Digital Outcrops |
| Geological research has focused on outcrops. Oblique photogrammetric technology, with the aid of unmanned aerial vehicles, can build 3D digital outcrop models and further help achieve visualization research of outcrops, providing new ideas for solving the problems of low efficiency, high risk, and poor data reusability that exist in traditional geological research methods. This study investigates the key technologies of 3D modeling of oblique images, 3D visualization of digital outcrops, visualization of panoramic models, and the design and implementation of a web platform for real-scene 3D digital outcrops based on the Cesium open-source 3D earth engine. The platform facilitates the visualization of high-precision 3D models of outcrops and combines outcrop-related information such as text, pictures, videos, panoramas, documents, observation stops, and geological plotting with 3D outcrop models, implementing upload and roaming of 3D models of outcrops, and self-supply, sharing, interaction, and visualization of outcrop-related information. Moreover, the applicability and novelty of the platform for online geological field trips are demonstrated through experiments. As the first choice for virtual field trips at the 21st International Congress of Sedimentology, the platform has been successfully applied to 12 of the 15 routes. Compared with traditional geological research methods, the visualization of 3D outcrops enables geologists to acquire a more comprehensive and intuitive understanding of the spatial and temporal distribution of geological phenomena as well as the features of outcrops. This platform also enables the co-construction and dissemination of outcrop resources in a digital environment, saving the time and economic costs associated with geological expeditions. |
