Solution Overview

Problem

Existing object tracking technologies face issues with cumulative error, reduced robustness, and wasteful computing power due to fixed field of view (FoV) settings, which affect tracking accuracy and efficiency.

Innovation Solution

The method dynamically adjusts the FoV based on the target tracking state, using predetermined reference FoVs to optimize the search region size and reduce errors, enhancing accuracy and reducing computational waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a fixed field of view (FoV) is used for object tracking, then the tracking system maintains consistent computational load, but cumulative error increases and tracking accuracy decreases over time

Engineering Contradiction:
Improvetracking accuracyVSAvoiderror accumulation
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies dynamics by transitioning from a fixed FoV to a dynamic FoV that adapts based on target tracking state. The system adjusts the search region size in real-time according to target stability, allowing the tracking window to expand when targets are unstable or move rapidly, and contract when targets are stable. This dynamic adjustment prevents error accumulation by maintaining appropriate search regions throughout the tracking process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the FoV size parameter based on target tracking state. The system changes the search region dimensions dynamically, expanding the FoV when prediction confidence is low or target movement is significant, and reducing the FoV when tracking is stable. This parameter adaptation resolves the contradiction by maintaining measurement precision while preventing error accumulation through state-dependent adjustments.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a fixed field of view (FoV) is used for object tracking, then the system structure remains simple, but computational resources are wasted and tracking robustness is reduced

Engineering Contradiction:
Improvetracking robustnessVSAvoidcomputational power
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial or excessive action by adjusting the FoV size according to actual tracking needs. When targets are stable, the system uses a smaller search region (partial action), reducing computational power consumption. When targets become unstable or move rapidly, the system expands the search region (excessive action) to maintain tracking robustness. This adaptive approach ensures computational resources are allocated efficiently while maintaining reliability.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent implements feedback mechanisms by continuously monitoring target tracking state and using this information to adjust the FoV dynamically. The system evaluates prediction confidence and target stability metrics, then feeds this information back to modify the search region size. This closed-loop control improves tracking robustness by responding to actual tracking conditions while optimizing computational resource usage through state-dependent adjustments.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If a fixed field of view (FoV) is used for object tracking, then the search region remains constant, but tracking adaptability to different target states is reduced

Engineering Contradiction:
Improvetracking adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the search region adaptive rather than static. The system dynamically adjusts the FoV based on real-time target tracking state, including prediction confidence and target stability measurements. This dynamic behavior enables the tracking system to adapt to different target states (stable, unstable, moving rapidly) while maintaining manageable complexity through rule-based adjustment logic.

Inventive Principle:
Principle #15Dynamics

AI summary

A method with object tracking includes: determining a first target tracking state by tracking a target from a first image frame with a first field of view (FoV); determining a second FoV based on the first FoV and the first target tracking state; and generating a second target tracking result by tracking a target from a second image frame with the second FoV.
