Multi-Object State Correction Using Shared Relative Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to achieve precise and consistent determination of the state of multiple objects in an association, particularly in dynamic environments where absolute and relative state values are necessary for accurate navigation and control.
Innovation Solution
A method involving each object in the association recording its own absolute and relative states, exchanging these values, and calculating a correction value to ensure consistent and precise absolute state estimation by applying the correction value to its own state, either locally or centrally through a central unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If absolute navigation methods are used to determine state values of objects in an association, then the absolute position can be obtained, but the precision and consistency of relative state determination deteriorates
Solution Approach 1:
The patent implements feedback by using recorded relative state values to calculate correction values that are applied to absolute state values. Each object in the association records its own absolute state and relative state to other objects, then uses this feedback information to correct its absolute state determination, thereby improving the consistency and precision of relative state determination while maintaining absolute position accuracy.
2Measurement precision
If correction values are calculated and applied to all objects in the association, then the absolute state determination precision is improved, but the data processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the correction calculation process into individual object-level operations. Each object independently calculates its own correction value based on its recorded absolute and relative state values, rather than requiring centralized processing for all objects. This segmentation reduces overall data processing complexity while maintaining improved precision across the entire association.
3Loss of information
If all objects exchange their recorded states via data connections, then the uniform information status is achieved, but the communication overhead and time consumption increase
Solution Approach 1:
The patent merges the information exchange process by having all objects in the association share their recorded absolute and relative state values through data connections. This consolidation of information allows each object to achieve a uniform information status, enabling accurate correction value calculation while optimizing the balance between information uniformity and communication efficiency.

AI summary
A method for determining a correction value of a state of an object in an association with a plurality of objects. The method includes: each object in the association recording its own absolute state in an existing coordinate system; a first object in the association recording a relative state of the first object in relation to one or more other objects in the association; the first object transmitting the recorded relative state and its own recorded absolute state via a data connection to one or more of the other objects in the association; exchanging recorded relative states and recorded absolute states in the association of objects so that all objects have the same uniform information status; each object calculating a correction value for all objects in the association based on the uniform information status; an object applying its own correction value to its own recorded absolute state.
