Technical Report Overview
Technical reports provide comprehensive assessments of vehicle collisions by analyzing damage patterns, vehicle metadata, and accident context. Our machine learning models process vehicle damage images along with detailed vehicle information (make, model, year, VIN, safety features) to calculate critical crash metrics.
How It Works
- You provide: Vehicle damage photos, vehicle metadata, and accident context
- ML computes: Delta-V, PDOF, impact type, collision type, damage severity
- Report generated: PDF with crash dynamics, damage assessment, and methodology
What You Provide
| Input | Description |
|---|---|
| Damage Photos | Vehicle damage images (1-20 per vehicle) |
| EDR Data | Event Data Recorder file (optional, provides precise measurements) |
| Vehicle Info | Make, model, year, VIN, vehicle type |
| Safety Systems | Seatbelt usage, airbag deployment status |
| Accident Context | Date, time, location, description |
| Occupants | Optional - for integrated biomechanics analysis |
What ML Computes
These values are calculated automatically from your evidence - do not provide them as inputs:
| Computed Field | Description | Source |
|---|---|---|
| Delta-V | Change in velocity during impact (mph) | Damage patterns or EDR |
| PDOF | Principal Direction of Force (0-360°) | Damage location analysis |
| Impact Type | Frontal, rear, side, angular | Derived from PDOF |
| Collision Type | Detailed collision classification | Derived from PDOF |
| Peak Acceleration | Maximum deceleration (g's) | EDR data when available |
| Damage Severity | Zone-based damage scores | Image analysis |
Two-Vehicle Analysis
The API supports both single-vehicle and two-vehicle crash scenarios:
- Plaintiff Vehicle (required): The primary vehicle in the accident reconstruction, typically the client's vehicle
- Defendant Vehicle (optional): The other vehicle involved in the collision - omit for single-vehicle crashes
- Accident Metadata: Contextual information including date, time, location, and description to enrich the analysis
Integrated Biomechanics
Technical reports can include automatic biomechanics analysis by providing occupant data. When occupants are included:
- Crash parameters (Delta-V, PDOF) are automatically used for biomechanics calculations
- Each occupant receives an individual biomechanics report
- No need to create a separate biomechanics request
See Create Report for occupant data structure.
What's Included in a Report
Each technical report contains:
- Delta-V Calculations: Minimum and maximum change in velocity (mph) during impact
- Confidence Score: Statistical confidence level (0-100%) of the analysis based on image quality and damage visibility
- PDOF Analysis: Principal Direction of Force angle (0-360°) indicating the primary impact direction
- Zone-Based Damage Scores: Detailed damage assessment for each vehicle zone (front, rear, sides, roof)
- Calculation Method: The analysis approach used (ML-based, crush depth analysis, or hybrid)
- Analyzed Zones: List of vehicle areas that were successfully assessed from the provided images
Evidence Quality Tips
For best results:
- Multiple angles: Provide 3-5 photos from different angles for each vehicle
- Close-ups: Include close-up shots of damage areas
- Good lighting: Ensure damage is clearly visible
- EDR data: When available, EDR provides the most accurate measurements
