Drawing on comprehensive research into the defect detection methods used by OEMs and end-users, the TVDM system utilizes a human-like imaging mechanism. By simulating the standard "chevron" lighting pattern common in automotive paint inspection and employing a striped light source combined with multi-angle observation, the system produces high-visibility images of paint defects that align with human visual perception.

Two Existing Visual Inspection Solutions for Paint Film Quality in the Industry:

Overview of the TVDM Detection System Architecture:

Defect lifecycle and full-process production management chain covering detection, display, editing, and statistical analysis.

Detection: uses visual imaging and defect recognition technology to identify coating or surface defects.
Display: defects are visualized and classified by vehicle body zones for intuitive analysis.
Editing: supports inspection line result review, modification, and confirmation.
Statistics: automatically generates reports and electronic statistical records for quality traceability and process optimization.

High-Precision Real-Time Positioning Defect Enhancement Display System

In addition to conventional screen-based visualization methods, a high-precision projection tracking display system can also be adopted. The system is equipped with 2–4 projection units, which project defect information onto the corresponding positions of the moving vehicle body based on their exact spatial coordinates, enabling intuitive and position-synchronized defect visualization.

TVDM Visual Inspection System Interface Display：

The system integrates multiple modules including optics, mechanics, electronics, software, and algorithms to achieve accurate defect detection.

Structured light field analysis technology: modulates structured light fields to enhance defect feature visibility and improve detection clarity.

Flexible workshop adaptation technology: distributed intelligent system supporting defect result display, editing, statistical analysis, and review functions.

Multi-view imaging technology: high-resolution multi-angle imaging enables clear large-area field-of-view inspection.

Human-like intelligent inspection technology: AI-based human-simulated detection and analysis algorithms for accurate defect identification and classification.
