Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement space information processing systems face challenges in managing processing loads due to frequent vehicle changes, leading to inefficient data traffic and inadequate flexibility in obtaining information from other vehicles, which is not limited to vehicles but can occur with other moving bodies as well.
Innovation Solution
A movement space information processing system that includes multiple moving bodies and an information processing device, where each moving body has a communication unit, image acquisition unit, and control unit to extract and transmit probe information, and the information processing device determines representative moving bodies based on the development of spatial information within a predetermined movement range to adjust data traffic and improve spatial information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If probe information is collected from all moving bodies, then the completeness of spatial information is improved, but the processing load and data traffic increase significantly
Solution Approach 1:
Multiple moving bodies are merged into a single representative moving body for information collection purposes. The identification unit determines one representative moving body from multiple moving bodies in the same region, and only this representative transmits probe information to the information processing device. This combining approach maintains spatial information completeness while significantly reducing the number of data sources and processing load.
Solution Approach 2:
The patent extracts only the essential function of information collection by selecting a single representative moving body from the group. Instead of processing information from all moving bodies, the system extracts and utilizes only the probe information from the identified representative, thereby reducing data traffic and processing complexity while maintaining the necessary spatial information coverage.
2Measurement precision
If probe information is collected from all moving bodies, then the accuracy of spatial information is improved, but the data traffic increases
Solution Approach 1:
The patent combines multiple moving bodies into a single representative information source. By merging the information collection function across multiple bodies into one representative moving body, the system reduces data traffic volume while maintaining spatial information accuracy through strategic selection of the representative based on development degree of spatial information.
3Adaptability or versatility
If the system identifies representative moving bodies based on development degree of spatial information, then the flexibility in obtaining information is improved, but the complexity of determination increases
Solution Approach 1:
The identification unit performs preliminary determination of the representative moving body based on the development degree of spatial information before actual probe information collection. By pre-identifying which moving body should serve as the representative in each region, the system enables flexible information acquisition without requiring complex real-time decisions during data collection, thus balancing adaptability with determination complexity.

AI summary
A movement space information processing system includes moving bodies and an information processing device. The information processing device determines one or more moving bodies that are movably located within a predetermined movement range in the space from the moving bodies, and performs an identification task of identifying, from the determined one or more moving bodies, at least one moving body to accordingly perform a setting task of setting the identified at least one moving body as the at least one representative moving body. At least one moving body identified as the at least one representative moving body acquires an image of the space and extracts, from the image, probe information related to the space. The information processing transmits device The moving-body information item including the probe information and performs development of the spatial information based on the probe information.
