Solution Overview

Problem

Existing techniques for identifying vehicle brands and models require frequent retraining when new vehicles are introduced or existing vehicles modify their shapes, logos, or license plates, and consume high computational resources with high latency.

Innovation Solution

A computing system that uses a processor and memory to obtain video frames from video capturing devices, detecting text or logos using convolution neural networks to identify vehicle brands and models, employing image processing and character recognition techniques to accumulate and match recognized text with a mapping table.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing techniques use logo-based identification with convolution neural networks, then brand identification accuracy is improved, but computational resources and processing time increase significantly

Engineering Contradiction:
Improvebrand identification accuracyVSAvoidcomputational resources
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system segments the identification task into two distinct paths: text-based OCR identification and logo-based CNN identification. This segmentation allows the system to choose the more efficient text-based approach when applicable, reducing computational resource usage while maintaining high identification accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the identification parameter from purely visual logo recognition to text-based character recognition when text is present. This parameter change from image-based CNN processing to text-based OCR processing significantly reduces computational complexity and energy consumption while maintaining or improving identification accuracy.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If existing techniques retrain models for new vehicles or modified shapes, then identification accuracy is maintained, but time and computational overhead increase

Engineering Contradiction:
Improveidentification accuracyVSAvoidretraining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The text-based OCR system is inherently adaptable to new vehicles and modifications without requiring retraining. The system automatically adjusts to new brand names, model names, and text formats through its existing character recognition capabilities, eliminating the need for time-consuming retraining processes while maintaining high identification accuracy.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If existing techniques process multiple vehicle features, then comprehensive identification is achieved, but system complexity increases

Engineering Contradiction:
Improveidentification coverageVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically switches between text-based and logo-based identification methods based on the presence of text in the captured image. This dynamic approach simplifies the system architecture by providing a clear decision pathway while maintaining comprehensive identification coverage through the dual-method capability.

Inventive Principle:
Principle #15Dynamics
