Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire inspection methods are manual, time-consuming, prone to errors, and limited in providing comprehensive information about tire condition, especially regarding wear and damage beyond tire pressure.
Innovation Solution
A computerized method and system for automatic tire inspection using image acquisition, segmentation, text detection, and deep learning models to analyze tire images for condition assessment, including pressure monitoring and anomaly detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection is performed, then inspection can be conducted with simple equipment, but inspection is time-consuming and prone to human error
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical inspection system using image acquisition devices, deep learning models, and computer processing. The system captures images of tires, processes them through segmentation and text recognition modules, and automatically determines tire conditions, eliminating human manual inspection while improving both speed and accuracy.
2Productivity
If tire inspection is automated with TPMS, then inspection speed increases, but only partial information (tire pressure) is provided
Solution Approach 1:
The patent creates a multi-functional inspection system that goes beyond单一 tire pressure monitoring. The system performs multiple functions including tire pressure assessment, tread depth measurement, tire condition evaluation, and text recognition (DOT codes, manufacturing dates). By integrating these diverse inspection capabilities into one system, it provides comprehensive tire information while maintaining high automation and speed.
3Loss of information
If comprehensive tire inspection is performed manually, then complete tire information is obtained, but the process becomes more time-consuming and complex
Solution Approach 1:
The patent implements continuous automated inspection processing where image acquisition, segmentation, text recognition, and analysis occur in an uninterrupted automated sequence. The system continuously captures tire images, processes them through deep learning models in real-time, and generates comprehensive inspection reports without human intervention, thereby obtaining complete tire information much faster than manual methods while maintaining continuous operational flow.

AI summary
There are provided a system and a method of automatic tire inspection, the method comprising: obtaining at least one image capturing a wheel of a vehicle; segmenting the at least one image into image segments including a tire image segment corresponding to a tire of the wheel; straightening the tire image segment from a curved shape to a straight shape, giving rise to a straight tire segment; identifying text marked on the tire from the straight tire segment, comprising: detecting locations of a plurality of text portions on the straight tire segment, and recognizing text content for each of the text portions; and analyzing the recognized text content based on one or more predefined rules indicative of association between text content of different text portions at given relative locations, giving rise to a text analysis result indicative of condition of the tire.
