Positioning Data Mapping for Reduced-Bandwidth Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronization of large amounts of positioning information from numerous smart devices in a space scene creates significant bandwidth pressure due to the large data volume of position and orientation information, which is typically represented by 32-bit floating-point data.
Innovation Solution
A data synchronization method that maps positioning information into number data with a smaller data amount, such as area position and orientation area numbers, using pre-configured mapping algorithms to reduce the data volume before transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning information (32-bit floating-point data) is transmitted directly from smart devices, then positioning accuracy is maintained, but bandwidth pressure increases significantly
Solution Approach 1:
The patent changes the data representation parameters by mapping continuous 32-bit floating-point positioning data to discrete integer grid coordinates. This parameter transformation reduces data precision requirements while maintaining sufficient positioning accuracy for the application scenario, thereby decreasing data volume without completely sacrificing positioning precision
Solution Approach 2:
The patent creates a simplified copy of the positioning information by mapping real-world coordinates to a virtual grid system. Instead of transmitting the original high-precision floating-point coordinates, the system transmits integer grid coordinates that represent the same spatial location, reducing data size while preserving essential positioning information
2Measurement precision
If large amounts of positioning data are synchronized in real-time, then synchronization accuracy is improved, but bandwidth pressure increases
Solution Approach 1:
The patent transforms the data parameters from high-precision floating-point format to low-precision integer format through grid mapping. This parameter change enables efficient real-time synchronization with reduced data transmission requirements, maintaining synchronization accuracy while significantly reducing bandwidth consumption
Solution Approach 2:
The patent segments the continuous space into discrete grid cells, allowing positioning information to be represented by integer coordinates rather than continuous floating-point values. This segmentation enables efficient real-time synchronization by reducing the data transmission burden while maintaining sufficient spatial resolution
