Moving Object Position Estimation Across Manufacturing Steps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for estimating the location or position of a moving object, such as a vehicle, during manufacturing face challenges due to changes in the object's appearance as manufacturing progresses, leading to incorrect estimation results.
Innovation Solution
A system comprising sensors to acquire appearance information, a step information acquisition unit to track manufacturing progress, a comparison information acquisition unit to retrieve relevant comparison information based on the manufacturing step, and an estimation unit to accurately estimate the location or position of the moving object by comparing the acquired information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If appearance information is compared using fixed comparison data, then the system is simple to operate, but estimation accuracy deteriorates as manufacturing progresses
Solution Approach 1:
The system dynamically selects comparison information based on the current manufacturing step rather than using fixed comparison data. The estimation unit acquires step information indicating the current manufacturing step and selects comparison information corresponding to that step, allowing the system to adapt to appearance changes as manufacturing progresses while maintaining operational simplicity
Solution Approach 2:
The system changes the parameter of comparison information selection based on manufacturing step progression. By linking comparison information to specific manufacturing steps, the system adjusts which comparison data is used according to the current state of the moving object, thereby maintaining estimation accuracy throughout the manufacturing process
2Measurement precision
If comparison information is acquired for every manufacturing step, then estimation accuracy is maintained, but processing burden increases
Solution Approach 1:
The comparison information acquisition unit automatically determines whether to acquire new comparison information by checking if the current manufacturing step differs from the previous step. When the step is the same, it reuses existing comparison information without additional acquisition, thereby reducing processing burden while maintaining accuracy when needed

AI summary
A system comprises: a sensor that acquires appearance information containing the appearance of a moving object movable by unmanned driving; a step information acquisition unit that acquires step information about progress of a step of manufacturing the moving object; a comparison information acquisition unit that acquires comparison information representing the appearance of the moving object responsive to the step information; and an estimation unit that estimates at least one of the location and position of the moving object by making a comparison between the comparison information and the appearance information.
