AR Template Environment Map for Cross-Environment Display

The patent segments the environment map into multiple regions with different degrees of freedom. The template environment map is divided into a first region with six degrees of freedom and a second region with three degrees of freedom. This segmentation allows the system to maintain high display accuracy in the primary viewing area while enabling adaptability to different environments through the simplified secondary region, resolving the contradiction between precision and versatility.

The patent creates a template environment map that can be universally applied to multiple different real environments. By extracting common structural features and creating a reusable template with defined regions of freedom, the same template can be adapted to various scenes without requiring separate three-dimensional measurements for each environment, thus achieving both accuracy and adaptability.

The patent performs preliminary action by pre-generating a template environment map that captures essential spatial relationships and structures. This template serves as a reusable foundation that can be quickly adapted to different environments through region-based transformations, eliminating the need to perform complete three-dimensional shape measurements for each new environment and significantly improving content generation efficiency.

The patent uses copying by creating a template environment map that can be replicated and adapted across multiple environments. Instead of generating unique content for each scene, the system copies the template structure and modifies it through region-based transformations, maintaining accuracy while dramatically improving productivity through reusable templates.
