Tracking Device Spatial Map Segmentation for Memory Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking devices face a significant memory resource burden due to the need to store large spatial map information, which reduces their operational efficiency.
Innovation Solution
The tracking system separates spatial map information into sub-regions based on the operating range of each tracking device, allowing only the relevant sub-regions to be loaded into memory, reducing the overall memory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all spatial map information is loaded into the tracking device memory, then positioning accuracy is improved, but memory resource burden increases
Solution Approach 1:
The patent divides the complete spatial map information into multiple sub-regions based on spatial coordinates. Each tracking device is assigned to load only the sub-regions relevant to its operating area, rather than loading the entire map. This segmentation reduces memory consumption while maintaining positioning accuracy in the device's specific operational context.
Solution Approach 2:
The patent implements local quality by tailoring the spatial map data loaded into each tracking device according to its specific role configuration and operating range. Different devices receive different subsets of spatial sub-regions optimized for their local operational needs, rather than uniformly loading all map data. This ensures each device has sufficient data for its specific positioning requirements without unnecessary memory burden.
2Measurement precision
If complete spatial map information is stored in the tracking device, then coordinate alignment accuracy is improved, but operation efficiency decreases
Solution Approach 1:
The spatial map is segmented into multiple sub-regions, and each tracking device loads only the necessary sub-regions for its operating area. This reduces the total data volume that needs to be processed, thereby improving operation efficiency while maintaining coordinate alignment accuracy within the device's specific operational context through selective data loading.
3Weight of moving object
If lightweight tracking devices are used, then device portability is improved, but memory capacity is reduced
Solution Approach 1:
The patent enables lightweight tracking devices with limited memory capacity to function effectively by segmenting the spatial map into sub-regions. Each device loads only the necessary sub-regions for its operating area, reducing the memory requirement from the full map size to a manageable subset that fits within the constraints of portable, lightweight device hardware.
Solution Approach 2:
The system optimizes for local quality by providing each lightweight device with precisely the spatial data it needs for its specific operating range and role configuration. This targeted approach ensures that devices with limited memory capacity can perform accurate tracking without requiring large memory allocations, thus maintaining portability while achieving functional requirements.
