Automating Dent and Scratch Detection

A Revolutionary Approach to Quality Control in Automotive Manufacturing

Get Started

The Challenge: Traditional Quality Inspections

In a leading automotive manufacturing facility, the quality assurance (QA) team has been responsible for manually inspecting newly manufactured vehicles to identify dents and scratches. This process, while critical to ensuring high-quality standards, has several limitations.

  • Manual Inspection Process:QA team members visually inspect the exterior of each vehicle, marking any detected defects.
  • Challenges:Time-consuming and labor-intensive.
  • Inconsistent results due to human error and subjective judgment. ○ Limited documentation, leading to delayed feedback for production teams.
  • Difficulty in detecting minor or subtle imperfections, which often go unnoticed.

With the increasing volume of vehicles being produced and the need for precision, the current inspection process became a bottleneck in the production line, affecting both speed and accuracy.

The Vision: Automating the Detection Process

Pixl was tasked with proving the feasibility of automating the dent and scratch detection process. The goal was clear: to implement a system that uses high-resolution cameras and AI-driven detection techniques to automate quality inspections on the production line.

  • Pixl’s vision was to demonstrate an automated solution capable of detecting and classifying dents and scratches in real-time, as vehicles moved through the production line, improving both efficiency and accuracy.

    • Solution: Automated Dent and Scratch Detection System

    Pixl introduced an innovative, AI-based solution designed to revolutionize the way vehicle quality inspections are carried out.

    High-Resolution Cameras:

    • Positioned strategically along the production line, these cameras cover all sides of the vehicle.
    • Challenges:Time-consuming and labor-intensive.
    • The cameras capture minute details and surface defects at high speed, ensuring no imperfection goes unnoticed as the vehicle moves along the conveyor belt.

    AI-Based Image Processing:

    • The captured images are processed by advanced AI algorithms designed to detect and classify defects into specific categories such as dents or scratches.
    • The system analyzes the images in real-time, providing precise feedback to the QA team, including the exact location and severity of each defect.

    Automated Reporting:

    • Real-time reports are generated, complete with image evidence and detailed defect locations.
    • These reports are automatically shared with the QA team, significantly reducing the time needed for manual documentation and ensuring faster, more informed decision-making.

    The Process: Phases of Implementation

    The implementation of this automated system followed a structured and phased approach to ensure feasibility and smooth integration into the production environment:

    • 1. Discovery Phase:Understanding the current process, identifying key pain points, and setting project goals.
    • 2. Model and Algorithm Development:Developing AI models and algorithms to accurately detect and classify dents and scratches on vehicle surfaces.
    • 3. Model Training with Sample Datasets:Training the AI models using sample datasets to improve the system's accuracy and ability to identify defects of various sizes and types.
    • 4. Site Visit and Testing:Conducting site visits to test the system in real-world conditions, ensuring its ability to handle high-speed production environments and deliver real-time results.

    The Benefits: Unlocking the Future of Quality Control
