Image Display System Spatiotemporal Browsing

The patent transitions from two-dimensional map images to three-dimensional virtual globe representation. By displaying geographical information as a 3D globe that can be rotated, zoomed, and explored from multiple angles, the system simultaneously achieves high resolution (through synthetic imagery) and enhanced browsing capability (through spatial manipulation), resolving the contradiction between resolution and adaptability.

The patent implements nested viewing capabilities where users can zoom into specific regions of the virtual globe to explore internal structures and details. The system nests multiple levels of magnification and detail within the overall geographical context, allowing users to maintain awareness of the broader environment while exploring specific areas in depth, thus preserving spatiotemporal information without sacrificing ease of operation.

The patent implements automatic object recognition and annotation systems that autonomously identify, classify, and label geographical features, objects, and phenomena in the virtual globe environment. The system performs self-service by automatically generating informative annotations without requiring manual keyword selection from users, thereby dramatically improving information retrieval efficiency while the annotated interface maintains operational simplicity through automated guidance.

The patent employs pre-processing and caching mechanisms where synthetic high-resolution imagery is generated and stored in advance for frequently accessed regions and time periods. By performing preliminary actions of image synthesis and storage before user requests, the system reduces real-time processing time while maintaining high measurement precision, effectively resolving the contradiction between resolution and processing time.
