Vehicle Road Data Acquisition Selective Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for acquiring road information from moving vehicles collect excessive data, making it difficult to process and store, as they capture images and sensor values from all vehicles, rather than selectively acquiring relevant information based on the type of road and vehicle.
Innovation Solution
An information acquisition apparatus equipped with a storage unit, determination unit, and identifying unit in a moving vehicle that records and analyzes road information based on the vehicle's movement, determining the type of road and associating it with the vehicle type to selectively acquire and store relevant data.

1Area of stationary object
If images and sensor values are collected from all general vehicles, then the coverage of road information collection is improved, but the amount of data becomes enormous making it difficult to process and store
Solution Approach 1:
The patent segments the data collection process by dividing vehicles into different types (first type vehicles and second type vehicles) and assigning different collection rules to each segment. First type vehicles collect road surface images continuously, while second type vehicles only collect images when specific conditions are met (crack detection by sound sensor or vehicle stopping). This segmentation reduces overall data volume while maintaining comprehensive road coverage.
Solution Approach 2:
The patent applies local quality by making the data collection strategy adaptive to local conditions - the collection behavior changes based on the vehicle type, road section characteristics, and real-time sensor readings. Instead of uniform collection from all vehicles, each vehicle type has optimized collection parameters suited to its characteristics and operating context.
2Measurement precision
If dedicated vehicles travel to collect road surface images, then the quality and completeness of road information is improved, but the time and effort required for collection increases
Solution Approach 1:
The patent makes general vehicles serve multiple functions - they continue their normal transportation role while simultaneously performing road inspection duties. This eliminates the need for dedicated inspection vehicles and the time loss associated with separate collection trips. The same vehicles that transport passengers or goods also capture road surface images and sensor data during their regular operations.
Solution Approach 2:
The system enables vehicles to self-select when and what to collect based on their own sensor readings and operational state. Second type vehicles autonomously determine whether to collect images based on crack detection by sound sensors or stopping status, without requiring external coordination or dedicated collection schedules, thereby reducing time loss while maintaining data quality.

AI summary
An information acquisition apparatus provided in a moving object (vehicle) that moves on a road includes: a storage unit that records therein information about the road that is acquired based on movement of the moving object on the road; a determination unit that determines the type of the road on which the moving object moves and determines whether the road is of a predetermined type defined in association with the type of the moving object; and an identifying unit that identifies the information about the road acquired based on the movement of the moving object on the road of the predetermined type and recorded in the storage unit.
