Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If key points are detected from captured images using conventional techniques, then key point detection can be performed, but the accuracy of the detected key points is insufficient

Engineering Contradiction:

Improvekey point detection accuracyVSAvoidtracking reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where detection results from multiple captured images are evaluated against appropriacy conditions, and correction parameters are determined based on this evaluation to improve subsequent key point detection accuracy

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary evaluation of detection results to determine appropriacy conditions before finalizing key point detection, using multiple captured images to pre-assess detection quality and determine correction parameters in advance

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If multiple captured images are processed to improve key point accuracy, then detection precision improves, but processing time and computational complexity increase

Engineering Contradiction:

Improvekey point detection accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by selectively processing only those captured images that satisfy predetermined appropriacy conditions, rather than processing all available images, thus reducing computational burden while maintaining accuracy improvements

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A key point correction apparatus detects a plurality of key points of a target object from each of a plurality of captured images. The key point correction apparatus decides whether or not a plurality of key points of the target object detected from the captured image satisfy an appropriacy condition. When the key points of the target object satisfy the appropriacy condition, the key point correction apparatus determines a correction parameter regarding the target object using the key points. When a correction parameter has been determined for the target object detected from the captured image, the key point correction apparatus corrects the key points of the target object using a correction parameter.
