Car Damage Estimation System using Deep Convolutional Neural Network

Turn vehicle images into structured evidence that helps reviewers locate visible damage and assess preliminary severity more quickly and consistently.

Funded · Fiscal year 2023 · One-year project

THE RESEARCH STORY

Begin with the decision—not the model.

A motor claim moves through image collection, component inspection, severity assessment and repair-cost review. Much of this work depends on human inspection and can slow down under high volume. This project studies where computer vision can organize preliminary evidence and improve consistency without replacing accountable review.

RESEARCH INSIGHT

Faster claims should not mean careless claims. A useful system reduces repetitive work, structures the evidence and exposes uncertainty so reviewers can focus attention on cases that genuinely require judgement.

PRIMARY RESEARCH QUESTION

What must the study resolve?

How reliably can a model locate visible damage, identify affected vehicle regions and estimate preliminary severity from images captured under real operating conditions?

OBJECTIVES

  1. 01

    Develop image-based detection and classification of visible exterior damage

  2. 02

    Study preliminary severity assessment that remains traceable to visual evidence

  3. 03

    Design a prototype that prioritizes review and escalates uncertain cases

METHOD ARCHITECTURE

From input to accountable support

The method is organized as an evidence chain. Every transformation should preserve enough context to explain what entered the system, what the model inferred, how confidence was assessed and when a person must review the case.

  1. 01

    Image intake and quality checks

  2. 02

    Vehicle and exterior-part detection

  3. 03

    Damage localization and classification

  4. 04

    Preliminary severity estimation

  5. 05

    Evidence package for human review

WORK PACKAGES

Four connected research responsibilities

Data

Design image collection across viewpoints, lighting, vehicle types and damage severity with traceable annotation rules.

Models

Compare detection, segmentation and classification without relying on unrealistically clean test data.

System

Connect the prototype to mobile or retrospective image workflows and preserve reviewable evidence.

Evaluation

Measure accuracy, time, reviewer consistency and cases that must be escalated to specialists.

EVIDENCE PLAN

What the project should produce

A research project is stronger when its outputs can be inspected independently of the final model score. The dossier therefore separates artifacts from evaluation.

Expected research assets

  • Prototype for external vehicle-damage detection and classification
  • Traceable image-collection and annotation protocol
  • Evaluation suite covering accuracy, speed and uncertainty
  • Escalation workflow for complex cases requiring reviewers
  • Research assets for publication, IP or industry co-development

Evaluation dimensions

  • Detection and segmentation quality
  • Severity agreement with reviewers
  • Calibration and abstention quality
  • Inference and end-to-end review time
  • Performance across lighting, viewpoints and vehicle groups

RESEARCH TRANSLATION

From prototype to a credible working system

Potential users include insurers, repair networks, service centres, inspectors, claim-platform developers and fleet operators. Operational integration still requires defined data access, image standards, audit trails and accountable decision ownership.

LIMITATIONS AND RESPONSIBLE FRAMING

The boundary is part of the research design.

This is a preliminary decision-support system, not an autonomous claim approver. Images may not reveal structural damage, and repair valuation also requires parts, labour, policy conditions and accountable human inspection.

This dossier communicates the documented project design and intended evaluation. It does not convert a proposal, funded status or prototype into a claim of validated operational performance. Numerical results should be cited only from a resulting peer-reviewed publication or verified project report.
