Mobile Terminal Still-Image Selection for Road Defect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies face inefficiencies in determining road defects from captured videos and issues with image rights and compensation for image providers and users.
Innovation Solution
A mobile terminal equipped with a position obtainer, image capturer, determination unit, and image transmitter that selects and transmits still images satisfying specific conditions, along with a centralized information processing device for accumulation and reward processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all still images in captured video are analyzed to determine road defects, then comprehensive defect detection is achieved, but processing efficiency deteriorates
Solution Approach 1:
The determination unit performs defect determination on only a selectively extracted subset of still images from the video rather than all images. This partial action approach maintains reliable defect detection for critical images while significantly improving processing efficiency by skipping unnecessary image analysis.
2Quantity of substance
If images are collected from drive recorders for defect analysis, then defect data is obtained, but rights processing issues arise for image providers and users
Solution Approach 1:
The mobile terminal automatically performs image selection, defect determination, and data transmission without requiring manual rights negotiation. The system self-manages the image collection and submission process, reducing the complexity of rights processing while maintaining defect data availability.
3Measurement precision
If multiple selection conditions are applied to filter still images, then image selection precision is improved, but determination process complexity increases
Solution Approach 1:
The determination unit divides the image selection process into multiple independent evaluation stages, each checking specific conditions (e.g., defect presence, image quality, relevance criteria). This segmentation allows precise multi-condition filtering while managing complexity through modular, stepwise decision-making.

AI summary
A mobile terminal including: a position obtainer configured to obtain a positional information; an image capturer configured to obtain a video including a still image during a movement, the video being associated with the positional information; a determination unit configured to determine whether or not the still image included in the video obtained by the image capturer satisfies a selection condition; and an image transmitter configured to transmit the still image which is determined to satisfy the selection condition by the determination unit while being associated with the positional information obtained by the position obtainer, wherein the determination unit is configured to obtain one or more attribute values associated with the still image, determine whether or not the one or more attribute values satisfies an inspection condition, and determine whether or not the still image determined to satisfy the inspection condition satisfies the selection condition.
