Solution Overview

Problem

Existing image detection methods fail to accurately characterize target structures in high-resolution images, as they ignore width information of line segments, leading to ineffective feature representation.

Innovation Solution

An image detection method that establishes a data model using mark point information of strip-like line segments, including length, width, direction, and center coordinates, and a priori model based on the distribution and number of line segments, employing probability density functions and sampling techniques to obtain a globally optimal solution for target model detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If width information of line segments is ignored to simplify the detection model, then the model construction is easier and faster, but the detection accuracy deteriorates in high-resolution images

Engineering Contradiction:
Improvemodel construction simplicityVSAvoiddetection accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent transforms the line segment representation from 1D (ignoring width) to 2D strip-like structures by introducing width as a new parameter. This parameter change enables the model to accurately represent target structures in high-resolution images while maintaining computational feasibility through probabilistic modeling approaches.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent adds the width dimension to line segments, transforming them from simple 1D elements into 2D strip-like structures. This dimensional expansion allows the model to capture the full geometric characteristics of target structures, resolving the contradiction between model simplicity and detection accuracy.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If strip-like line segments with width information are used to improve feature representation, then detection accuracy improves, but the data model complexity increases

Engineering Contradiction:
Improvefeature representation accuracyVSAvoiddata model complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional deterministic geometric modeling with probabilistic modeling using point process theory. This substitution allows the complex strip-like line segment data to be handled through probability density functions and statistical methods, simplifying the overall model while maintaining high detection accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces probability density functions as an intermediary layer between the raw strip-like line segment data and the detection algorithm. This intermediary transforms complex geometric information into probabilistic representations, making the data more manageable and the model less complex while preserving feature representation accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If traditional line segment models are used for low-resolution images, then the detection process is efficient, but the model fails to characterize target structures accurately in high-resolution images

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent creates a dynamic modeling approach where the line segment representation adapts to image resolution requirements. For low-resolution images, the model can operate with simplified representations, while for high-resolution images, it automatically utilizes the full strip-like structure with width information, maintaining both efficiency and reliability across different scenarios.
