Stage Anchor Map Standardization for Cross-Device 3D Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing localization systems lack standardization, security, and accuracy in generating stage anchor maps for three-dimensional scenes, particularly in extended reality environments, due to variations in sensor types, operating systems, and captured-image formats.
Innovation Solution
A system that generates a standard-format stage anchor map using image and sensor data, converting data into an intermediate format via an API, and then into a final standardized format like SLAM, without exposing device-specific 3D information, enabling localization of multiple recording devices within a 3D scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If device-specific 3D mapping processes are used to generate stage anchor maps, then localization accuracy for each device is improved, but system standardization and cross-device compatibility deteriorate
Solution Approach 1:
The patent introduces a standardized intermediate representation (stage anchor map) as an intermediary between device-specific 3D mapping processes and the localization system. This intermediate format serves as a universal language that translates diverse device-specific mappings into a common standard, enabling cross-device compatibility while preserving localization accuracy through the mediation of standardized coordinate transformations and reference frames.
Solution Approach 2:
The patent transforms device-specific mapping parameters into standardized parameters through coordinate system transformations. By changing the representation parameters from device-specific coordinate systems to a unified standard format, the system maintains the precision of individual device mappings while achieving interoperability across different devices and platforms.
2Adaptability or versatility
If device-specific 3D information and processes are exposed in stage anchor maps, then device functionality and processing capabilities are improved, but system security and information protection deteriorate
Solution Approach 1:
The patent extracts and separates device-specific 3D mapping processes and information from the final stage anchor map output. By taking out the proprietary processing logic and device-specific data, the system retains only the essential standardized location information needed for localization, thereby protecting device functionality and information while maintaining system security.
Solution Approach 2:
The patent segments the localization system into distinct functional layers: device-specific mapping processes, standardized intermediate representation, and localization services. This segmentation isolates sensitive device information from the shared standardized interface, allowing device functionality to be maintained in isolated modules while preventing information exposure through the standardized boundary.
3Adaptability or versatility
If multiple intermediate format conversions are performed to achieve standardization, then cross-device compatibility is improved, but processing time and system complexity deteriorate
Solution Approach 1:
The patent performs preliminary conversion of device-specific formats into the standardized intermediate representation during the mapping process itself, rather than delaying conversion until needed. By preparing standardized data structures and coordinate transformations in advance, the system reduces real-time processing requirements and minimizes conversion time when localization is performed.

AI summary
Various implementations disclosed herein include devices, systems, and methods that uses image and sensor data to generate a standard-format stage anchor map identifying positions of elements of a 3D scene. For example, an example process may include obtaining image data and camera data from one or more cameras of an electronic device while the electronic device is within a three-dimensional (3D) environment. The process may further include converting the image data and camera data into a first data set having a first format specified by a map-generation process. The process may further include generating a stage anchor map by inputting the first data set into the map-generation process. The stage anchor map may identify positions of anchors corresponding to elements of the 3D environment. Likewise, the stage anchor map may be used to localize a plurality of camera devices capturing images of the 3D environment during a filming session.
